peptide
Peptides are short chains of amino acids that can signal skin cells to produce more collagen and elastin. The category is broad and evidence quality varies dramatically — some peptides (like Matrixyl) have decent clinical data, while many others are supported by little more than in vitro studies and marketing enthusiasm.
brightener
Niacinamide is one of the most versatile and well-researched skincare actives available. It regulates sebum production, strengthens the skin barrier, fades hyperpigmentation, and minimizes pore appearance — all with minimal irritation risk. If you could only pick one active, this would be a strong contender.
