Infact, niacinamide is helpful for damaged skin.
Common signs of damaged skin that Niacinamide can help with:
Here is how niacinamide can help this damaged skin:
Skin barrier strengthening
The top layer of skin acts as a barrier/shield. It prevents water from evaporating from the skin and protects the skin from attacks from environmental nasties. These attacks can cause breakouts in the skin.
If the top layer of skin works well, skin stays hydrated with fewer or no breakouts.
Ceramides is a compound found in the skin that helps the top layer in its barrier function. Niacinamide helps in the production of ceramides.
Niacinamide helps strengthen the top layer of skin, keeps skin hydrated and minimises breakouts.
Anti-inflammation
Inflammation and redness can cause breakouts and dark spots/pigmentation on the skin.
Niacinamide reduces inflammation and redness on the skin.
Regulates oil production
Niacinamide regulates oil production. This is particularly helpful for oily skin.
Less excess oil means less acne and other breakouts on the skin, as well as a reduction in pore size.
