WIMJ summary for anti-aging
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
