Each 20ml bottle carries 15% niacinamide alongside zinc PCA and acetyl glucosamine, a trio aimed at the things that bother oily and breakout-prone skin most: shine, visible pores, rough texture and the brown or red marks that linger after a pimple has gone.\u003c\/p\u003e\n\u003cp\u003eThe formula is short, with only fifteen ingredients, and the texture is a light, slightly slippery serum that disappears quickly. It is designed to sit between toner and moisturiser and to layer cleanly under sunscreen, which makes it practical for both morning and evening routines.\u003c\/p\u003e\n\u003ch3\u003eIs 15% niacinamide too strong?\u003c\/h3\u003e\n\u003cp\u003eIt is at the higher end of what you will find in skincare. Many people tolerate it well, especially oily skin types, but if you have never used niacinamide or your skin is reactive, start slowly or begin with a gentler, lower-strength option first.\u003c\/p\u003e\n\n\u003ch2\u003eCOSRX The Niacinamide 15 Serum benefits: what it does for your skin\u003c\/h2\u003e\n\u003cp\u003eNiacinamide is one of the most versatile actives in skincare, and this serum puts it to work on several concerns at once.\u003c\/p\u003e\n\u003ch3\u003eLess shine through the day\u003c\/h3\u003e\n\u003cp\u003eNiacinamide and zinc PCA help balance oil, so skin that turns shiny by lunchtime in Karachi's humidity tends to stay fresher for longer with regular use.\u003c\/p\u003e\n\u003ch3\u003eSmoother-looking pores and texture\u003c\/h3\u003e\n\u003cp\u003eWhen oil is better controlled and the surface is gently refined by acetyl glucosamine, pores look less prominent and rough patches feel smoother.\u003c\/p\u003e\n\u003ch3\u003eFading the look of post-acne marks\u003c\/h3\u003e\n\u003cp\u003eNiacinamide helps even out the look of skin tone, so dark marks left by old breakouts gradually look softer. Pair it with daily sunscreen; without sun protection, marks linger far longer.\u003c\/p\u003e\n\u003ch3\u003eA calmer, stronger barrier\u003c\/h3\u003e\n\u003cp\u003eNiacinamide also supports the skin's barrier, and allantoin adds a soothing touch. Over time, many people find their skin less reactive and better able to handle other actives.\u003c\/p\u003e\n\n\u003ch2\u003eCOSRX The Niacinamide 15 Serum key ingredients\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eIngredient\u003c\/th\u003e\n\u003cth\u003eWhat it does\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eNiacinamide (15%)\u003c\/td\u003e\n\u003ctd\u003eBalances oil, refines the look of pores, evens tone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eZinc PCA\u003c\/td\u003e\n\u003ctd\u003eHelps regulate sebum and calm the look of breakouts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAcetyl glucosamine\u003c\/td\u003e\n\u003ctd\u003eGently refines the surface and supports a brighter look\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAllantoin\u003c\/td\u003e\n\u003ctd\u003eSoothes and comforts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTrehalose\u003c\/td\u003e\n\u003ctd\u003eHelps hold moisture in the skin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThere is no added fragrance, no essential oils and no alcohol in the ingredient list, which keeps the formula focused and easier on sensitive-leaning skin.\u003c\/p\u003e\n\n\u003ch2\u003eIs COSRX The Niacinamide 15 Serum right for your skin type?\u003c\/h2\u003e\n\u003ch3\u003eOily and combination skin\u003c\/h3\u003e\n\u003cp\u003eThis is where it shines.

You can use it with vitamin C, such as the \u003ca href=\"\/products\/cosrx-the-vitamin-c-23-serum-20ml\"\u003eCOSRX The Vitamin C 23 Serum\u003c\/a\u003e, but if your skin is sensitive, use vitamin C in the morning and niacinamide in the evening. Avoid stacking it with several strong exfoliants on the same night.\u003c\/p\u003e\n\n\u003ch2\u003eCOSRX The Niacinamide 15 Serum results: how long until you see a difference?\u003c\/h2\u003e\n\u003cp\u003eMost people notice less shine and a smoother feel within two to three weeks. The look of pores and texture usually improves over four to eight weeks, while post-acne marks take longer, often two to three months of consistent use together with daily sunscreen. Everyone's skin is different, so give it at least a month before judging.\u003c\/p\u003e\n\n\u003ch2\u003eDoes COSRX The Niacinamide 15 Serum have side effects?\u003c\/h2\u003e\n\u003cp\u003eThe most common reaction is temporary tingling or mild redness, usually in the first week and usually when the serum is applied to freshly washed, damp skin or layered with exfoliants. Applying it to dry skin and using it every other day at first helps. Niacinamide should not cause purging, so if you see a cluster of new breakouts that does not settle, pause and let your skin recover.\u003c\/p\u003e\n\n\u003ch2\u003eCOSRX Niacinamide 15 vs ANUA Niacinamide serum\u003c\/h2\u003e\n\u003cp\u003eBoth are popular niacinamide serums, but they suit different needs.\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003e\u003c\/th\u003e\n\u003cth\u003eCOSRX The Niacinamide 15\u003c\/th\u003e\n\u003cth\u003eANUA Peach 70% Niacinamide\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eStrength\u003c\/td\u003e\n\u003ctd\u003eHigh (15%)\u003c\/td\u003e\n\u003ctd\u003eGentler daily dose\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMain focus\u003c\/td\u003e\n\u003ctd\u003eOil, pores, post-acne marks\u003c\/td\u003e\n\u003ctd\u003eGlow and gentle brightening\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTexture\u003c\/td\u003e\n\u003ctd\u003eLight, slippery serum\u003c\/td\u003e\n\u003ctd\u003eMilky, hydrating serum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBest for\u003c\/td\u003e\n\u003ctd\u003eOily skin used to actives\u003c\/td\u003e\n\u003ctd\u003eBeginners and sensitive skin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eChoose COSRX if oil and pores are your main concern and your skin is used to actives.
