Niacinamide and lipohydroxy acid: keep them apart

Keep them apart

Use them at different times of day, applying the hydroxy acid first and niacinamide later, because combining them causes irritation. Using both at once overloads your skin with too much exfoliation and activity, leading to redness and dryness. To fix this, you can leave more time between applications or switch to a gentler product.
