The Truth About Pore Strips, Pore Vacuums, and 'Shrinking' Your Pores
You cannot shrink a pore. But you can change how visible it is — and almost everything sold to 'minimize' pores is pulling the wrong lever.
Promising for Large Pores
What Makes This Different
It pairs a prominent niacinamide dose with a low level of retinal, a peptide and a ceramide-cholesterol barrier blend in a fragrance-free, watery base, a gentle way to introduce a retinoid into an oily-skin routine.

Retinal-Lite Pore Serum
serum serum dermatologist developed Paraben Free Not Cruelty Free
A gentle, fragrance-free pore serum that is really a well-built niacinamide serum with a small retinal accent. It trims shine and smooths texture over weeks without the peeling of stronger retinoids, which makes it a smart first retinoid for oily or sensitive skin; anyone expecting a potent retinal treatment should look elsewhere.

Review
Full Review
The bottle says Nano-retinal RX Complex, and retinal is a genuinely exciting ingredient. It sits one step closer to retinoic acid than retinol does, converting more efficiently in the skin, and research has shown it can deliver retinoid effects faster and at lower concentrations. So it is reasonable to expect the Fation Nosca9 Pore Enhancing Serum to behave like a retinal treatment. The ingredient list, published in full by Olive Young Global, tells a different story. Retinal appears fourth from the end of a fifty-plus ingredient list, after the ceramides and cholesterol. The ingredient that sits near the top, sixth after water and a group of humectants, is niacinamide. That changes how to think about this serum, and it is mostly good news.
Niacinamide is one of the best-supported ingredients for oily, pore-prone skin. Studies have linked it to reduced sebum production and a smoother-looking surface over several weeks, and it supports barrier function and helps even out tone. At its position here, it is present in a meaningful amount, and in practice it is responsible for most of what users notice: less shine by afternoon and a slightly more refined look to the nose and cheeks. The product is registered in Korea as a functional cosmetic, reflecting its niacinamide and adenosine content.
The retinal, then, is an accent rather than the engine. At its level, it is unlikely to cause the purging, peeling or stinging associated with stronger retinal serums, and it may add a modest boost to texture over months of use. For people who have never used a retinoid, or whose skin reacts badly to them, that gentleness is an advantage. For experienced retinoid users looking for a step up, this is not the product.
The supporting cast is thoughtful. A small barrier blend of ceramide NP, ceramide AP, cholesterol and phosphatidylcholine sits alongside the retinal. Palmitoyl pentapeptide-4, a signal peptide, and adenosine target firmness and fine lines. Glycerin, propanediol, sorbitol, betaine, trehalose and sodium hyaluronate make it hydrating, and panthenol, allantoin and dipotassium glycyrrhizate keep it soothing. Chlorella and apple extracts are included for oil control claims. Sodium heparin and Korean mugwort, the hallmarks of the Nosca9 line, appear at the very end. There is no fragrance and no drying alcohol.
The texture is watery and slightly slippery, and it disappears within seconds, leaving no stickiness. It layers easily under moisturiser and sunscreen and does not pill. Because the retinoid dose is so low, it can be used morning and evening, which is unusual for a retinal product; sunscreen remains essential either way, as it is for anyone trying to improve texture and marks.
Expectations around pores deserve honesty. Pore size is largely genetic and influenced by sebum output and skin elasticity. Reducing oil, keeping pores clear and improving surface texture can make them look smaller, but no serum physically shrinks them. Most people will notice less shine within two to four weeks and a smoother surface after eight to twelve weeks of consistent use.
Building a routine around it is straightforward. For oily, congested skin, a low-pH cleanser, a salicylic acid toner used two or three evenings a week, this serum morning and night, a light gel moisturiser and daily sunscreen make a complete, well-balanced plan. For combination skin, the serum can go all over while a richer cream is kept for dry cheeks. Because the retinal is gentle, it is also a sensible bridge for someone planning to move to a stronger retinoid later: a few months on this serum lets you gauge how your skin handles retinoids at all, with the niacinamide and ceramides cushioning the transition. When you do step up, keeping this serum for the mornings avoids stacking retinoids at night.
There are a few cautions. Retinal is a retinoid, so even at a low level, the serum is best avoided during pregnancy, which is standard advice. It contains olive oil and fatty esters, which makes it a less obvious choice for fungal-acne-prone skin. And sodium heparin is animal-derived, so it is not vegan.
On value, StyleKorean lists the 30 millilitre bottle at twenty-one dollars, with regular discounts, and larger sets are available from Olive Young Global. That is fair for a fragrance-free niacinamide serum with a well-rounded supporting formula, though it is slightly steep if you think of it as a retinal product, given the low dose.
Fation is the derma brand of Dong-A Pharmaceutical, launched in 2018, and its Nosca9 line is known for gentle trouble care. This serum is a 2024 addition, so reviews are still limited, and no independent clinical testing has been published.
The bottom line: treat it as a gentle, fragrance-free niacinamide serum with a light retinoid accent, and it performs well, especially for oily, combination and sensitive skin new to retinoids. Treat it as a strong retinal treatment, and you will be underwhelmed.

|---|---|---|
| Niacinamide | Sixth in the list and the real workhorse here: the best-evidenced ingredient in the formula for oil control and a finer-looking pore appearance, well ahead of the retinal the bottle promotes. | Limited for Large Pores |
| Retinal | The nano-retinal of the label, a potent retinoid, but placed near the very end after the ceramides and cholesterol, so it adds a gentle retinoid nudge rather than a treatment-strength dose. | Not yet assessed |
| Ceramide NP | Part of a small ceramide, cholesterol and phosphatidylcholine blend that supports the barrier alongside the niacinamide, helping the retinal sit comfortably. | Not yet assessed |
| Palmitoyl Pentapeptide-4 | A signal peptide listed next to the retinal, added for firmness claims around pores; present at a low level. | Not yet assessed |
| Adenosine | Supports Korea's functional wrinkle-care registration and adds a gentle anti-ageing element to the pore-focused formula. | Limited for Aging |

Evidence
Science & Expert Perspective
The Science
Niacinamide (vitamin B3) has been studied for oily skin and enlarged pores; controlled trials have reported reductions in sebum excretion rate and improvements in the appearance of pores and texture after several weeks of topical use, typically at 2 to 5 percent. It also increases ceramide synthesis and supports barrier function, which is useful alongside a retinoid.
Retinal (retinaldehyde) is converted in the skin to retinoic acid in a single oxidation step, compared with two steps for retinol, and research has shown it can produce retinoid-like effects on epidermal turnover and collagen gene expression. Studies of retinaldehyde have generally used concentrations of about 0.05 to 0.1 percent. Its placement here, after cholesterol and ceramide AP, suggests a considerably lower level, consistent with a gentle, low-irritation formula. Encapsulation or nano-delivery, as the brand describes, can improve stability, but evidence for this specific complex has not been published.
Palmitoyl pentapeptide-4 is a signal peptide derived from a collagen fragment; manufacturer and small clinical studies suggest it can improve the appearance of fine lines, though independent evidence is limited. Adenosine is a Korean-registered functional ingredient for wrinkle improvement with modest clinical support. Ceramides, cholesterol and phosphatidylcholine together mimic components of the skin's lipid barrier.
Sodium heparin, the centrepiece of the Nosca9 line, is a sulfated glycosaminoglycan with anti-inflammatory activity reported in laboratory research; its contribution in a cosmetic serum at the end of the ingredient list is uncertain.
Dermatologist Perspective
For oily skin and enlarged-looking pores, dermatologists commonly recommend topical retinoids, niacinamide and salicylic acid, together with sun protection. Low-strength retinoids and retinaldehyde are often suggested as starting points for patients who have not used retinoids before or who have sensitive skin, with gradual increases as tolerated. Clinicians generally advise avoiding retinoids during pregnancy. Fragrance-free formulations are preferred for sensitive and acne-prone skin. Patients are usually counselled that pore size cannot be permanently reduced by topical products, and that improvements in oiliness and texture take several weeks.
Guidance
Usage & Recommendations
How to Use
After cleansing and toner, apply two or three drops to the face and pat gently until absorbed. It can be used morning and evening. Follow with a moisturiser and, in the morning, broad-spectrum sunscreen. If you use a prescription retinoid, keep this serum for the mornings. Sensitive skin can start once daily and increase as tolerated. Avoid combining it with strong exfoliating acids on the same night if your skin is reactive. Do not use during pregnancy.
Value Assessment
At about $21.00 for 30 ml on StyleKorean, often discounted, the serum is fairly priced for a fragrance-free niacinamide formula with a ceramide barrier blend, peptide, adenosine and a gentle retinal accent. Viewed as a retinal treatment, it is less compelling, because the retinoid dose is low. The small bottle means twice-daily users will repurchase every six to eight weeks. Dong-A Pharmaceutical's backing supports quality, though the brand's claims are not independently tested.
Who Should Buy
People with oily, combination or sensitive skin who want a fragrance-free serum to reduce shine and refine texture, especially those looking for a gentle first retinoid.
Who Should Skip
Experienced retinoid users wanting a potent retinal will find it too mild. Anyone pregnant, trying to conceive or managing fungal acne should choose a different serum.

Myth vs. Reality
Common Myths
Myth
A retinal serum will cause purging and peeling.
Reality
This serum's retinal sits near the end of the list, so most people experience no purging; niacinamide does most of the visible work.
Myth
Pore serums shrink pores permanently.
Reality
Pore size is largely genetic. Reducing oil and improving surface texture makes pores look smaller, but they do not physically close.
