Numbuzin No. 1 Clear Filter Sun Essence SPF 50+ PA++++ squeeze tube
Good choice for Sensitivity
What Makes This Different

Nearly 50% of this formula is functional botanical extracts (licorice root water, centella asiatica, houttuynia cordata) rather than plain water — creating a calming, treatment-level base for the UV filters. Combined with a modern European-Korean photostable filter system (Tinosorb S, Uvinul T 150, DHHB) and an eight-type hyaluronic acid complex, this treats sunscreen as a skincare step rather than just UV protection.

K-Beauty Sunscreen Star
sunscreen essence k beauty Paraben Free Cruelty Free

A genuinely impressive K-beauty sunscreen that replaces nearly half its water base with calming botanical extracts, pairs modern photostable UV filters with an eight-type hyaluronic acid complex, and somehow manages to feel like a lightweight skincare serum rather than sun protection.

Review

Full Review

The idea is deceptively simple: if a sunscreen's base is mostly water anyway, why not replace that water with something that actually does something for the skin? Numbuzin's No. 1 Clear Filter Sun Essence takes this premise and runs with it, using 20.55% licorice root water, 15% centella asiatica extract, and 14.25% houttuynia cordata extract as the foundational liquid base. That is nearly fifty percent of the formula dedicated to calming, anti-inflammatory botanicals before you even get to the UV filters.

This is not merely a marketing gimmick. These are three of the most well-studied anti-inflammatory plant extracts in Asian skincare science, each with documented mechanisms of action. Licorice root provides glabridin, a tyrosinase inhibitor that addresses hyperpigmentation. Centella asiatica delivers madecassoside and asiaticoside, compounds shown to promote collagen synthesis and reduce redness. Houttuynia cordata, sometimes called heartleaf, offers antioxidant and anti-inflammatory properties that Korean dermatology has valued for decades. Together, they create a base that actively works to calm and protect the skin rather than simply holding the UV filters in suspension. Behind them sits a long tail of hanbang botanicals — astragalus, goji berry, eclipta, polygonum, ophiopogon, kelp, aloe — that reads like a herbal apothecary and functions, realistically, as a supporting chorus rather than a second act.

The UV filter system itself is thoroughly modern. Ethylhexyl Triazone, Terephthalylidene Dicamphor Sulfonic Acid (Mexoryl SX), Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB), Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S), and Polysilicone-15 — this is a five-filter cocktail that covers both UVA and UVB with excellent photostability. Unlike formulas built around avobenzone, which degrades under UV exposure and needs to be stabilized, these newer-generation filters maintain their protective capacity throughout the day. The PA++++ rating, the highest possible under the Japanese/Korean system, confirms robust UVA protection — the wavelengths that drive photoaging and pigment rather than the ones that burn. It also puts a hole in the assumption that chemical filters are inherently harsh: this generation of molecules is far better tolerated than the ones that gave the category its reputation, and here they are suspended in a base engineered to calm.

The texture is where this sunscreen earns its devoted following. It is genuinely essence-like — watery, almost weightless, with a slight greenish tint that vanishes on contact with skin. There is no drag during application, no white cast afterward, no greasy residue that announces to the world that you are wearing sunscreen. Within seconds of application, the finish settles into a natural, dewy glow that looks like good skin rather than a protective layer. Butyloctyl salicylate and dibutyl adipate are doing the invisible work here, dissolving the filters into a liquid thin enough to disappear, while polymethylsilsesquioxane adds a whisper of soft focus. For anyone who has struggled to find a sunscreen that does not compromise the look and feel of their morning skincare routine, this is a revelation.

Niacinamide makes an appearance mid-formula, adding brightening and barrier-supporting properties that complement the botanical base. An eight-type hyaluronic acid complex provides layered hydration at different molecular weights — standard sodium hyaluronate for surface moisture, hydrolyzed forms for deeper penetration, and a crosspolymer that creates a sustained-release moisture depot. For a sunscreen, this is an unusually generous hydration system, and it is the reason the essence never leaves that faint tightness most chemical formulas do by mid-afternoon.

The lightness invites a fair question — does something this thin really deliver SPF 50+? It does, but only on the same terms as any other sunscreen. SPF is measured at a standardized two milligrams per square centimeter, which for a face translates to roughly two finger-lengths of product. Texture has nothing to do with protection; dose does. A thick sunscreen applied sparingly protects worse than a thin one applied properly, and the pleasure of this texture is precisely what makes the honest dose easy to apply.

Under makeup, the performance is excellent. The essence absorbs cleanly without leaving a tacky layer, so primers and foundations apply smoothly on top. Users report no pilling or separation throughout the day, though there is a caveat — applying the sunscreen immediately over heavier serums or oils without allowing absorption time can cause some balling. The solution is simple: let your skincare settle for a minute or two before applying, and give the sunscreen itself ten minutes before makeup. Reapplication every couple of hours still applies outdoors, which the slim flip-cap tube at least makes portable.

The limitations here are logistical, not chemical. Fifty milliliters is not a lot of sunscreen, especially when you are applying the recommended two-finger-length amount daily. At roughly eighteen dollars, you are looking at a monthly repurchase, which adds up over time. This is typical of Korean sunscreens — elegant texture comes at the cost of smaller packaging — but it is worth factoring into the value calculation.

For very dry skin in winter, this sunscreen alone may not provide enough moisture. It layers well over a richer moisturizer, but by itself, it is better suited to combination, normal, and oily skin types that appreciate the lightweight feel. In warmer months, it is a perfect standalone option for all but the driest skin. Anyone managing fungal acne should note the silicones and fatty alcohols and proceed accordingly.

Numbuzin is still a young brand — founded in 2019, with this product launching around 2023. There is no decades-long track record to point to, no body of independent clinical research on the specific formula, and the several hundred reviews that exist are enthusiastic but early. What exists is a smart, well-constructed product built with ingredients that are individually well-validated, packaged in a texture that makes daily sunscreen use feel like a pleasure rather than a chore. The formula itself speaks to a team that understands modern sunscreen chemistry and is not cutting corners on either the UV protection or the skincare components.

For anyone in the market for an elegant daily sunscreen that calms sensitive skin, leaves no white cast, plays nicely under makeup, and treats the UV protection step as an opportunity to deliver skincare benefits — this is one of the strongest options currently available in the K-beauty space.

Formula

Key Ingredients

The hero actives that drive this product's performance.

IngredientFunctionEvidence
Centella Asiatica Extract (15%) (15%) At a generous 15% concentration, centella asiatica provides the backbone of this sunscreen's calming claims. Working alongside the 20.55% licorice root water and 14.25% houttuynia cordata extract, it creates a soothing botanical base that helps mitigate the irritation potential of chemical UV filters — particularly relevant for sensitive and redness-prone skin that needs daily sun protection. Limited for Rosacea
Licorice Root Water (20.55%) (20.55%) The single highest concentration ingredient in the formula, licorice root water contributes anti-inflammatory and skin-brightening properties through its glabridin and glycyrrhizin content. As the primary solvent base alongside water, it replaces a significant portion of plain water with a functional botanical that supports the anti-redness positioning of this sunscreen. Limited for Hyperpigmentation
Niacinamide Positioned mid-list, niacinamide adds brightening and barrier-supporting properties to the sunscreen base. In this formulation rich with botanical extracts, it contributes to the post-application glow and helps maintain skin barrier integrity under chemical UV filter exposure throughout the day. Emerging for Hyperpigmentation
Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S) A photostable broad-spectrum UV filter that absorbs both UVA and UVB radiation. Part of the multi-filter system alongside Ethylhexyl Triazone (Uvinul T 150) and Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB/Uvinul A Plus). This modern European-Korean UV filter combination provides robust, photostable protection without the instability issues of older filters like avobenzone. Regulator-approved for Sun Damage · limited certainty
8 Types of Hyaluronic Acid Complex An extensive multi-weight hyaluronic acid complex including sodium hyaluronate, hydrolyzed variants, and crosspolymer forms. Different molecular weights penetrate to different depths, providing layered hydration that prevents the dehydrating effect many chemical sunscreens produce. The crosspolymer form creates a sustained-release moisture reservoir on the skin surface. Plausible mechanism for Dullness

Science & Expert Perspective

The Science

The botanical base of this sunscreen draws on well-established research. Centella asiatica at 15% brings madecassoside and asiaticoside, triterpenoid saponins that have been studied extensively for their wound-healing and anti-inflammatory effects. A 2012 study in the International Journal of Molecular Sciences demonstrated that madecassoside inhibits the NF-kB inflammatory pathway and promotes type I collagen synthesis — relevant for a product designed to calm irritation while protecting against UV-induced collagen degradation.

Glycyrrhiza glabra (licorice) root water at 20.55% provides glabridin, which inhibits tyrosinase activity and melanin transfer. A study reported in the Journal of Agricultural and Food Chemistry (2003) confirmed glabridin's ability to inhibit UVB-induced pigmentation in vivo at concentrations as low as 0.1%, making it a particularly appropriate ingredient in a sunscreen context where UV-induced hyperpigmentation prevention is the goal.

The UV filter system combines five modern organic filters. Tinosorb S (Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine) is a broad-spectrum filter that absorbs across the UVA and UVB range and also stabilizes other less photostable filters in the system. DHHB (Diethylamino Hydroxybenzoyl Hexyl Benzoate) provides dedicated UVA I protection (340-400nm), the most damaging wavelength range for photoaging. A 2007 study in Photochemical & Photobiological Sciences confirmed that combinations of Tinosorb S with complementary filters achieve synergistic photoprotection, meaning the combined SPF exceeds what each filter would achieve alone.

The eight-type hyaluronic acid complex represents current best practice in hydration technology, with different molecular weights targeting different skin layers. Hydrolyzed hyaluronic acid (low MW, <10 kDa) penetrates deeper into the epidermis, while sodium hyaluronate crosspolymer forms a sustained-release reservoir on the surface.

Dermatologist Perspective

Dermatologists increasingly recognize that sunscreen compliance is driven as much by cosmetic elegance as by SPF numbers — patients are far more likely to use a sunscreen they enjoy wearing daily. As a matter of routine clinical guidance, this formulation addresses the two most common reasons patients skip sunscreen: discomfort (white cast, heaviness, stinging) and irritation on sensitive skin. The modern UV filter system is photostable and well-tolerated, the calming botanical base is appropriate for redness-prone and post-procedure skin, and the fragrance-free formulation reduces sensitization risk. Dermatologists would note the one caveat that PA++++ ratings are measured under controlled laboratory conditions and that real-world protection depends heavily on adequate application amount and reapplication frequency.

Guidance

Usage & Recommendations

How to Use

Apply generously as the final step in your morning skincare routine, after moisturizer and before makeup. Use approximately two finger-lengths of product for the face alone, and don't forget the neck and ears. Allow 5-10 minutes for the sunscreen to set before applying makeup or heading outside. Reapply every 2 hours during extended outdoor sun exposure, or immediately after swimming or heavy perspiration. For office days with minimal sun exposure, a single morning application with a midday touch-up before going outside is generally sufficient.

Value Assessment

At approximately $18 for 50 ml, this sunscreen costs roughly $10.60 per fluid ounce — significantly more than drugstore options but competitive within the K-beauty premium sunscreen category. The generous botanical extract concentrations, modern UV filter system, and eight-type HA complex represent genuine formulation investment that justifies the positioning. However, the 50 ml size means monthly repurchasing at proper application amounts, so the annual cost approaches $200+ for daily use. For users who prioritize elegant texture and skin-calming benefits in their sunscreen, the value is strong. For those simply seeking adequate UV protection, more affordable options exist in larger formats.

Who Should Buy

Anyone seeking an elegant daily sunscreen that doesn't feel like sunscreen — particularly those with sensitive, redness-prone, or combination skin who have struggled with white cast, heaviness, or irritation from other formulas. Ideal for K-beauty enthusiasts who view sun protection as a skincare step, makeup wearers who need a smooth base, and anyone with hyperpigmentation concerns who wants both treatment and protection in one product.

Who Should Skip

Budget-conscious users who need a high-volume daily sunscreen — the 50 ml format makes this expensive for body application or frequent reapplication during outdoor activities. Those who prefer mineral/physical sunscreens for philosophical or regulatory preference reasons. Users in climates with extreme heat and humidity who need a fully matte, sweat-resistant sport sunscreen.

Background

The Story Behind This Product

Numbuzin's No. 1 line focuses on calming and soothing, and this sun essence brings that philosophy to daily UV protection. Developed for the Korean market where elegant sunscreen textures are the baseline expectation, it addresses the common complaint that chemical sunscreens irritate sensitive skin by replacing much of the water base with proven anti-inflammatory botanicals. It quickly became an Olive Young bestseller, validating the approach.

About Numbuzin Established Brand (5–20 years)

Numbuzin launched in 2019 from Korean beauty startup Benow (founded 2018). The brand has rapidly gained traction on Olive Young and global K-beauty platforms with its numbered product system. While it uses well-studied ingredients, independent clinical validation of its specific formulations is limited given its short market history.

Myth vs. Reality

Common Myths

Myth

Chemical sunscreens are always irritating for sensitive skin.

Reality

Modern chemical filters like Tinosorb S and DHHB are generally well-tolerated and significantly less irritating than older filters like oxybenzone. This formula further reduces irritation potential by embedding those filters in a base of calming centella, licorice root, and houttuynia cordata extracts.

Myth

The light texture means this sunscreen provides less protection than thicker formulas.

Reality

SPF is measured at a standardized application density (2mg/cm²) regardless of texture. This essence-type sunscreen provides SPF 50+ PA++++ protection when applied at the recommended amount. Thicker texture does not equal better protection — application amount does.

FAQ

Frequently Asked Questions

Does Numbuzin No. 1 Sun Essence leave a white cast?

No, this is a purely chemical (organic) sunscreen with no mineral filters like zinc oxide or titanium dioxide, so it leaves absolutely no white cast. The formula has a faint greenish tint that disappears upon application, leaving a natural dewy finish suitable for all skin tones.

Is Numbuzin sunscreen good for sensitive skin?

Yes, this formula is specifically designed for sensitive skin. Nearly 50% of the base consists of calming botanical extracts — 20.55% licorice root water, 15% centella asiatica, and 14.25% houttuynia cordata. These anti-inflammatory ingredients help buffer the chemical UV filters, and the formula is fragrance-free and alcohol-free.

Can I wear makeup over Numbuzin No. 1 Sun Essence?

Yes, the lightweight essence texture is specifically formulated to layer well under makeup. Allow 5-10 minutes for the sunscreen to fully set before applying primer or foundation. Users consistently report no pilling or separation when layered correctly, though pilling can occur if applied directly over certain heavy serums.

How often should I reapply Numbuzin sunscreen?

Like all sunscreens, this should be reapplied every 2 hours during continuous sun exposure, or immediately after swimming or heavy sweating. For indoor office days with minimal sun exposure, a single morning application with touch-ups before extended outdoor time is generally sufficient.

What UV filters does Numbuzin No. 1 Sun Essence use?

This sunscreen uses a modern photostable filter system including Ethylhexyl Triazone (Uvinul T 150), Terephthalylidene Dicamphor Sulfonic Acid (Mexoryl SX), Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB/Uvinul A Plus), Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S), and Polysilicone-15 (Parsol SLX).
