SkinCeuticals P-TIOX

It is a needle-free option that helps soften expression lines. Inspired by the effects of neurotoxin injections, its peptide complex is clinically shown to reduce the appearance of nine types of expression lines by up to 20.6% over 12 weeks. It will not replicate the effect of an in-clinic treatment, but it is an excellent choice if you would rather avoid needles or want to maintain results between appointments.

It is a peptide serum that helps reduce the appearance of nine types of expression lines — the dynamic wrinkles from repeated facial movement — while refining texture and revealing glass-skin radiance. PHA, niacinamide and laminaria extract support smoother, more even, hydrated skin.

Yes. In the morning, apply it after a vitamin C serum such as C E Ferulic. In the evening, apply it before retinol or a corrective cream. When layering serums, work from thinnest to thickest texture.

Yes. It is suitable for all skin types and tones, including sensitive skin — in fact, over half of the clinical study participants had sensitive skin. It is also fragrance-, paraben- and silicone-free.

It can be used from your mid-20s onwards. Skin's natural anti-ageing processes begin to slow around age 25, so introducing a peptide serum early can help soften existing expression lines and support smoother skin over time.

Glass-skin radiance is visible in as little as one week, with expression-line and texture improvements building over 12 weeks of consistent twice-daily use.

P-TIOX is retinoid-free, but it contains active ingredients including salicylic acid and niacinamide. As we're not able to give individual medical advice, we always recommend checking with your GP, midwife or a qualified skincare professional before using any active skincare during pregnancy or breastfeeding.
