5% Niacinamide Serum, Professional Strength, 1.75 fl oz (52 ml)

I’ve been using the Advanced Clinicals 5% Niacinamide Serum daily, and it’s been an absolute skincare staple for me. Here’s why I’m obsessed: Brightens Dark Spots & Evens Tone – I’ve noticed discoloration fading fast and more even-toned, radiant skin overall. Hydration Powerhouse – The hyaluronic acid and aloe vera combo means my skin feels plump and dewy all day without any greasiness. Soothing & Refreshing – Ferulic acid and natural fruit extracts give this serum a gentle, calming effect—perfect after long days or sun exposure. Lightweight & Fast-Absorbing – No leftover residue at all—just soft, smooth skin that's ready for moisturizer or makeup. Great Value – At 1.75 oz, this bottle lasts a long time and delivers such good results, especially compared to pricier serums. Since starting this serum, uneven tone and dark spots have noticeably improved, and my complexion looks healthier and more refreshed. Whether you're a skincare newbie or a vet, this bottle is pure gold! —Highly recommend adding it to your routine if you want brighter, hydrated, even-toned skin!

مره فرق في بشرتي

I have eczema where my skin pales at certain areas. It was able to soothe mys skin and even back my tone. It is light-weight and non greasy. Perfect for oily skin type. It absorbs quickly as well

Great! Has helpd with my dark spots.

Just got it but it is working great as expected. No stickiness that I can tell. I apply with Vitamin C serum. It is creamy as compared to many serums, having a whitish appearance. Moisturizes well in conjunction with the rest of my moisture regimen. Will buy again.
