Features          5.50 – 6.50 pH         Alcohol-free         Silicon-free         Oil-free         Gluten-free         Nut-free         Cruelty-free         Vegan Niacinamide, a skin-brightening ingredient that has been shown to diminish redness, irritation, and wrinkles, is featured in The Ordinary Niacinamide 10% + Zinc 1% serum, and you can shop it from Thebeautygarage's online store. It can even aid blemish hyperpigmentation and is gentle enough for sensitive skin. The serum's texture is really light, and it dries nearly immediately. Therefore, you should apply it after cleansing and toning before other serums or moisturizers. To use it, make sure to apply the product straight to your face with the dropper because it gets absorbed very quickly. However, using this serum might not be a good idea if you utilize vitamin C products since niacinamide degrades vitamin C's integrity.
