Why Niacinamide and Peptides Are Essential for Skin Barrier Repair

Niacinamide (Vitamin B3) is a multi-tasking ingredient that strengthens the skin’s natural barrier, reduces inflammation, and improves moisture retention. Peptides are small chains of amino acids that signal the skin to produce collagen and elastin, essential for firmness and elasticity.

Together, these ingredients help restore damaged skin, improve texture, and protect against environmental stressors, making them ideal for body lotions aimed at skin barrier repair.
