What does Niacinamide do for skin with dark spots?
Niacinamide helps fade dark spots and uneven pigmentation by slowing down the transfer of pigment in the skin. It is generally well tolerated and may improve overall skin brightness with consistent use.
Where does this serum go in a skincare routine for skin with dark spots?
This treatment goes in the evening routine after cleansing and toning, and before moisturizing. Using it at night keeps things simple and avoids extra sun sensitivity.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol, but it is best to apply them on alternate nights or separate them into your morning and evening routines to avoid irritation. Using azelaic acid and niacinamide helps fade dark spots and calm redness, while snail mucin keeps your skin hydrated and smooth.
