Ysthéal Intense concentré antirides rénovateur de peau

Uses retinol (not the gentler retinal in Avène) plus niacinamide, but lacks the peptide complex (oleoyl dipeptide-15/tetrapeptide-31) and evening primrose oil that support Ysthéal's anti-aging claim.

Marketed as anti-wrinkle night cream but ingredient list shows no retinal/retinol at all in the visible list beyond generic antioxidants, and it swaps peptides for butters and hyaluronic acid, so the hero actives don't align.

Relies on retinyl palmitate (weak ester, not retinal) and a different peptide/probiotic complex, so the actual anti-aging actives don't match Ysthéal's retinal-plus-peptide formula.

This is a nail serum using retinyl palmitate (a much weaker vitamin A ester) in an oil-based formula, missing the peptides and the active retinal strength that drive Ysthéal's wrinkle claims.

This is a stretch-mark serum using retinyl palmitate at likely low strength with maca/ginger extracts, missing the retinal and peptide actives that define Ysthéal's anti-wrinkle action.
