| Ingredient | What it is | What it does for skin |
|---|---|---|
| Retinol | A form of vitamin A used in skincare that skin converts into the active retinoic acid. | Supports skin renewal and visibly smooths fine lines and uneven tone with consistent use; it is among the most studied topical anti-aging ingredients.Note: Can cause dryness, peeling or sensitivity, especially when starting. Best used at night with daily sunscreen, and generally avoided during pregnancy and breastfeeding. |
| Bakuchiol | A plant-derived compound from babchi seeds, often described as a gentler alternative to retinol. | Small studies suggest it can improve the look of fine lines and uneven tone over time with less irritation than retinol, although it is not chemically a retinoid.Note: Less studied than retinol. Patch test first if your skin is sensitive. |
| Niacinamide | A form of vitamin B3, one of the most studied ingredients in cosmetic dermatology. | Strengthens the skin barrier by boosting ceramide production, helps even out tone by limiting pigment transfer to skin cells, and can reduce the look of enlarged pores. |
| Copper tripeptide-1 | A short peptide (GHK) bound to copper, studied in skin-repair and wound-healing research. | Used as a skin-conditioning peptide that supports the look of firmer, smoother skin; most of the evidence comes from small studies. |
| Acetyl hexapeptide-8 | A short synthetic peptide, sold under the trade name Argireline, often marketed as a topical alternative to wrinkle-relaxing injections. | Studied for softening the look of expression lines; effects are modest and mostly shown in short, brand-sponsored studies. |
| Asiaticoside | One of centella asiatica's primary triterpenoid glycosides, alongside madecassoside. | Studied for supporting wound healing and collagen synthesis; often included alongside madecassoside for a broader range of centella's soothing and repair-supporting effects. |
