Key ingredients
These are the ingredients IOPE highlights for this product, cross-checked against general dermatological and cosmetic-chemistry sources, not a full INCI list.
Fragrance: No fragrance or essential oil appears in the ingredient list on file; brand confirmation pending.
| Ingredient | What it is | What it does for skin |
|---|---|---|
| Hydroxypinacolone retinoate | A newer retinoid ester that acts on retinoid receptors without needing to be converted first. | Used for texture and fine-line care and is often better tolerated than retinol.Note: Retinoids can irritate, and they are generally avoided in pregnancy. Introduce gradually and keep using sunscreen. |
| 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. |
| 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. |
| Panthenol | Pro-vitamin B5, which converts to pantothenic acid once absorbed into skin. | Hydrates as a humectant, supports wound healing, and has anti-inflammatory, soothing effects on irritated skin. |
| Allantoin | A soothing compound, naturally occurring in some plants and also made synthetically. | Calms irritation and supports skin healing, often paired with other barrier-focused ingredients. |
| Adenosine | A compound naturally present in skin cells, used in skincare as an anti-aging active. | Recognized by South Korea's MFDS as a functional anti-wrinkle ingredient at 0.04% concentration, based on clinical studies showing measurable fine-line improvement; a real but modest effect, not a retinoid substitute. |
