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.
