Most 0.2 percent retinol serums are stinging and peeling territory for beginners. Selfless by Hyram encapsulates the retinol in phospholipids for slow release and stacks it with 2 percent tranexamic acid for post-acne mark fading. The combination of encapsulated retinol plus tranexamic acid in one serum is unusual at this price point, and specifically targets users coming off the breakout phase and into the scar-fading phase of their skincare journey.
Selfless by Hyram Retinol & Rainbow Algae Repair Serum Review
Beginner-Friendly Retinol
serumserumindieParaben FreeCruelty FreeVegan
A thoughtfully constructed retinol serum that genuinely earns its beginner-friendly claim. Phospholipid-encapsulated retinol at a meaningful 0.2 percent, stacked with 2 percent tranexamic acid for post-acne mark fading, in a fragrance-free vegan vehicle. If the last active you tried was The Ordinary and you are ready to move up, this is a sensible next step.
Roughly eight hundred reviews across Sephora, Amazon, and direct channels back this 2021 serum, giving the score a foundation of early user sentiment alongside analysis of its encapsulated retinol and tranexamic acid pairing. The brand benefits from The Inkey List's chemists, but mark-fading efficacy at this percentage hasn't been independently studied.

Review
Full Review
Most retinol serums ask you to pick one lane. Either you want anti-aging collagen turnover (pick a traditional free-retinol serum and brace for peeling) or you want brightening and pigmentation fading (pick vitamin C, tranexamic acid, or alpha arbutin separately). Selfless by Hyram's Retinol & Rainbow Algae Repair Serum quietly does both at the same time. It combines 0.2 percent pure retinol, encapsulated in phospholipids for slow release, with 2 percent tranexamic acid — the first for long-term collagen and texture work, the second for direct attack on post-acne marks and hyperpigmentation. It's not a dramatic chemistry innovation, but in the context of a $28 drugstore-adjacent serum aimed at retinol beginners, it is genuinely unusual.
The encapsulation is the technical trick worth explaining. Free retinol at 0.2 percent in a typical water-based serum is going to sting, flake, and potentially redden skin for the first two to three weeks of use. Phospholipid encapsulation changes the delivery profile by wrapping individual retinol molecules in lipid structures that release their contents gradually over hours rather than all at once. The practical result is that skin sees the retinol in smaller doses over a longer period, which dramatically reduces the initial irritation without meaningfully reducing the long-term efficacy. Studies on encapsulated retinoid delivery have been running for the better part of two decades, and the approach is well-established in cosmeceutical science even if it is still underused at this price point. The pedigree behind the label helps explain the competence: Selfless by Hyram launched in 2021 as a collaboration between YouTube skincare educator Hyram Yarbro and an established indie formulation house — meaning the chemistry came from working cosmetic chemists, not from an influencer's kitchen.
The supporting cast is smart. Squalane sits in the number two slot as the emollient backbone that cushions the retinol and reduces transepidermal water loss during the nighttime retinization process. Triolein, a natural triglyceride, adds further conditioning. Glycerin handles basic humectant duty. Rainbow algae extract — Cystoseira tamariscifolia, a French-sourced brown algae — contributes antioxidant support without adding potential irritation, and it gives the formula its distinctive brand identity. Tocopherol rounds out the antioxidant profile. And the formulation is genuinely fragrance-free, alcohol-minimal (the benzyl alcohol is a preservative rather than an ethanol drying agent), and vegan.
The first application tells you whether the encapsulation is doing its job. For most users the answer is yes — there is no sting, no warming, no flaking on day one. A very faint tingle is normal for the first couple of uses and settles quickly. Most beginners can build up to nightly use over two to three weeks without the classic retinol peeling phase. Some very reactive skin types still see mild flaking in the first one to two weeks; that is normal and manageable by scaling back to every other night. The cadence that works: every third night for two weeks, every other night for two more, then nightly as tolerated — with a barrier moisturizer over the top each time. Keep acids and benzoyl peroxide on different evenings, and treat the next morning's broad-spectrum sunscreen as part of the product's instructions rather than an optional extra.
The performance payoff unfolds in stages. Over two to four weeks you notice mild smoothing and subtle tone improvements — this is the retinol waking up cell turnover and the tranexamic acid starting to chip away at surface pigment. Over six to eight weeks the most visible change appears: post-acne marks and post-inflammatory hyperpigmentation fade noticeably, which is the tranexamic acid doing its specific job. Over twelve weeks you get the full retinol collagen benefit — softer fine lines, more even texture, and more light-reflective skin. None of these are dramatic results. All of them are the kind of sustained improvement that accumulates into meaningful change over months.
The limitations are honest. The 30ml dropper bottle is small and the price is mid-tier — you are paying about as much as you would for the comparable drugstore encapsulated retinols, which makes the premium for Selfless by Hyram's specific formulation debatable. Dropper bottles are not ideal for long-term retinol stability compared to true airless pumps, and the serum should be used within six months of opening to maintain potency. Benzyl alcohol is in the formula as a preservative and is generally well-tolerated, but a small minority of sensitive users can react to it. Reception among its first adopters runs solid: roughly 800 reviews averaging 4.3, concentrated among Hyram's famously ingredient-literate audience, with the praise centered on beginner tolerance and mark-fading, and the complaints on the small bottle and the mid-tier price. And because this is a real retinol product, it is not pregnancy-safe and requires daily SPF the morning after use.
The buyer profile: retinol beginners graduating from entry-level granactive formulas, users with post-acne marks or mild hyperpigmentation who want both retinol and tranexamic acid in one step, and fans of Hyram Yarbro's ingredient-literate approach. The skip list: anyone pregnant or nursing, people with severely compromised barriers or active rosacea flare-ups, and very experienced retinol users who want a higher percentage in a purer vehicle. For the first-to-second-step retinol journey, this serum is one of the more thoughtfully built options in its price range.
Formula
Key Ingredients
The hero actives that drive this product's performance.
The star active of this serum, retinol is encapsulated in phospholipids for slow release, which is the technical trick that lets Selfless by Hyram dose it at a meaningful 0.2 percent without the stinging and peeling that a free-retinol serum at the same concentration would cause. The encapsulation is what makes this a beginner-friendly retinol despite the assertive percentage.
A French-sourced brown algae extract used at 0.15 percent as part of a 1.5 percent complex. Positioned as a repair and antioxidant ingredient that supports the retinol's work without adding additional irritation potential — an unusual companion active that gives the formula its distinctive 'rainbow algae' identity.
A well-studied brightening ingredient included at 2 percent to specifically target post-acne marks and hyperpigmentation. In this serum it complements the retinol — where retinol provides collagen turnover and slow pigment evening, tranexamic acid addresses existing dark spots more directly.
Positioned second on the INCI list to deliver the emollient buffer that cushions the retinol and reduces transepidermal water loss during nighttime retinization. This high squalane placement is part of what makes the serum tolerable at its retinol percentage.
The carriers that encapsulate the retinol, enabling slow release and gentler delivery. These same phospholipids also contribute barrier support by mimicking native skin lipid structures.

Evidence
Science & Expert Perspective
The Science
The formulation science behind this serum rests on two well-established actives and a delivery technology worth understanding. Retinol's efficacy in stimulating collagen synthesis, normalizing keratinocyte turnover, and improving photoaged skin is one of the most thoroughly validated facts in cosmetic dermatology. Studies have repeatedly demonstrated meaningful clinical effects at concentrations ranging from 0.05 percent to 1 percent, with irritation rising sharply as concentration increases. The limiting factor for most consumers is not efficacy but tolerability. Phospholipid encapsulation addresses this tolerability gap by enclosing retinol molecules in lipid vesicles that gradually release their contents as the vesicles break down on contact with skin. Published research on liposomal and phospholipid-based retinoid delivery has shown equivalent or superior clinical benefit compared to free retinol at matched concentrations, with significantly reduced irritation markers. Tranexamic acid is a synthetic lysine derivative that inhibits plasminogen activation in keratinocytes, which reduces the melanocyte response to inflammation and UV exposure. Clinical studies have demonstrated topical tranexamic acid's effectiveness for melasma and post-inflammatory hyperpigmentation at concentrations of 2-5 percent, which is exactly the range used here. The combination of retinol and tranexamic acid is complementary rather than redundant — retinol works upstream on skin turnover and collagen, tranexamic acid works downstream on melanocyte behavior, and together they address both the texture and the pigmentation aspects of post-acne skin.
Dermatologist Perspective
Dermatologists commonly recommend encapsulated retinol formulations for patients who cannot tolerate free retinol at equivalent concentrations. A widely shared clinical view is that phospholipid or liposomal encapsulation reduces the acute irritation phase of retinoid use while preserving long-term benefits, making this approach useful for retinol beginners and sensitive-skin patients. Tranexamic acid is increasingly cited in dermatology literature as a safer and better-tolerated alternative to hydroquinone for mild to moderate hyperpigmentation, and its combination with retinol in one serum reflects current cosmetic dermatology best practice. Dermatologists caution that retinol should not be used during pregnancy or breastfeeding regardless of encapsulation, and that even encapsulated retinols can cause irritation in compromised skin barriers. Patients with active rosacea or eczema should consult their dermatologist before starting any retinoid.
Guidance
Usage & Recommendations
How to Use
Use at night only, after cleansing and any hydrating toner. Dispense 3-4 drops onto a clean fingertip and press gently into the face and neck, avoiding the immediate eye area and lips. Follow with a barrier-supporting moisturizer to buffer irritation. Start with every third night for 2 weeks, then every other night for 2 weeks, then nightly as tolerated. Always wear broad-spectrum sunscreen the next morning. Do not combine on the same night with AHAs, BHAs, benzoyl peroxide, or other retinoids. Stop use if you experience persistent redness, peeling, or burning, and reintroduce slowly.
Value Assessment
At $28 for 30ml, this serum sits in the mid-tier of indie retinol products. The 30ml bottle delivers roughly 60-80 doses with nightly use, lasting 2-3 months, which puts effective monthly cost around $9-14. Compared to The Ordinary's retinol or Granactive Retinoid options at $10-15, the price premium is real but defensible given the encapsulation technology and the added tranexamic acid. Compared to prestige retinol serums at $80 and up, this is a clear value choice. Only one size is offered, which is a minor limitation but appropriate for a product that needs to be used within six months of opening to maintain retinol potency.
Who Should Buy
Retinol beginners ready to start a real retinoid, users with post-acne marks or mild hyperpigmentation who want both retinol and tranexamic acid in one step, fans of ingredient-literate influencer brands, and anyone who has tried The Ordinary retinol products and wants to step up. Also a good choice for combination and oily skin prone to post-inflammatory hyperpigmentation.
Who Should Skip
Anyone pregnant or breastfeeding, users with active rosacea or severely compromised barriers, very experienced retinol users who want a higher percentage, and budget shoppers who prefer cheaper retinol options from The Ordinary or CeraVe. This one is also wrong for you if you cannot commit to daily sunscreen use the morning after.

How Long It Lasts
2-3 months with nightly use — the 30ml bottle delivers roughly 60-80 doses.
When Selfless by Hyram launched in 2021, the Retinol & Rainbow Algae Repair Serum was positioned as the brand's hero active treatment. Hyram had spent years on YouTube warning his audience about harsh retinoids and marketing-only ingredient claims; the encapsulation approach was chosen specifically to deliver a clinically meaningful retinol dose that his beginner-heavy audience could actually use. The rainbow algae extract — a less common ingredient — was added for its antioxidant profile and to give the formula a brand-specific identity.

Myth vs. Reality
Common Myths
Myth
All 0.2% retinol serums cause flaking and peeling.
Reality
Encapsulation fundamentally changes the delivery profile. This serum's phospholipid-encapsulated retinol releases slowly, which gives the skin time to adapt. Most beginners tolerate it better than a free-retinol product at 0.1 percent.
Myth
Tranexamic acid and retinol should not be used together.
Reality
They are genuinely complementary. Tranexamic acid addresses existing hyperpigmentation, while retinol addresses cell turnover and long-term collagen. They target different mechanisms and are safely combined at the concentrations used in this serum.
FAQ
Frequently Asked Questions
Is this serum good for first-time retinol users?
Yes — it is specifically designed for beginners. The phospholipid encapsulation slows retinol release, and the high squalane placement buffers irritation. Start with every third night and build up to nightly over 2-3 weeks.
Does it really help with post-acne dark spots?
Yes. The 2 percent tranexamic acid is well-studied for targeting post-inflammatory hyperpigmentation, and the retinol supports cell turnover. Most users see visible mark fading within 6-8 weeks.
Can I use it with niacinamide or hyaluronic acid?
Yes. Both pair safely and beneficially with retinol. Apply hyaluronic acid or niacinamide serum first, then follow with this retinol serum. You can also use a barrier moisturizer on top to buffer.
Does Retinol & Rainbow Algae Repair Serum contain anything to avoid during pregnancy?
No. All retinoids, including encapsulated retinol, are generally avoided during pregnancy and breastfeeding. Use azelaic acid or niacinamide for brightening during those periods.
Can I use it with vitamin C?
Not at the same time. Use vitamin C in the morning and this retinol serum at night to avoid irritation and potential reduced efficacy from pH conflicts.
How long does a 30ml bottle last?
Two to three months with nightly use, delivering roughly 60-80 doses. A pea-sized amount is enough for the full face.
How does it compare to The Ordinary's Granactive Retinoid?
Granactive Retinoid is a different molecule (hydroxypinacolone retinoate) that is gentler by nature. This serum uses true retinol encapsulated for controlled release, which is a distinct approach. Both are beginner-friendly, but Selfless by Hyram adds tranexamic acid for pigmentation specifically, which The Ordinary's version does not.
