A peptide serum for forehead lines, crow’s feet and frown lines
SkinCeuticals P-Tiox is an anti-wrinkle peptide serum for all skin types, designed to soften the look of expression lines. It pairs 2% hexapeptide and 2% dipeptide, known to help relax the look of contraction lines, with 5% PHA to smooth texture and 5% niacinamide to strengthen the barrier and even out tone. Laminaria extract hydrates and soothes. SkinCeuticals says it visibly improves nine types of expression lines, and it can be used alongside in-clinic injectable treatments.
The texture
A lightweight, watery serum that absorbs in seconds and leaves no film, so it layers easily under moisturiser and sunscreen. It is fragrance-free.
Who it suits
- Forehead lines, frown lines and crow’s feet
- Anyone looking for a peptide step in their routine
- People who have in-clinic wrinkle treatments and want a home complement
- All skin types, including sensitive skin
Worth knowing before you buy: the formula contains denatured alcohol and a little salicylic acid, which can sting on freshly irritated skin. Results on expression lines build gradually with daily use.
How long one bottle lasts
At 4 to 6 drops once or twice a day, the 30ml bottle lasts about two months.
