Result
This varies depending on your skin type; please discuss this with your doctor or a specialist.
Usage
Apply 5 to 6 drops twice a day to clean, dry skin. Gently pat the serum onto your forehead, cheeks, and chin, and let it absorb. Use it in the morning after your vitamin C serum, and finish with sunscreen.
Avoid contact with the eyes. The serum contains a mild exfoliating acid (PHA): if it causes irritation, use it less frequently. If you’re also using a peel or retinol, discuss the combination first.
Science
Peptides are short chains of amino acids. P-TIOX combines two peptides with PHA, a mild acid that exfoliates dead skin cells, and niacinamide (vitamin B3). In its own 12-week study, SkinCeuticals reports fewer visible expression lines and smoother skin. The serum works on the skin’s surface and does not alter muscle activity. Results vary from person to person.
Correct: targeted care after your antioxidant
SkinCeuticals divides skincare into three steps: prevent, correct, and protect. P-TIOX Serum falls under the “correct” category: targeted care that you apply after your antioxidant serum and before your sunscreen.

No. P-TIOX is a cosmetic skincare product that you apply to the skin. Botox is a medical treatment in which a doctor injects a medication into a muscle. SkinCeuticals has tested the serum as a complement to such a treatment; it works differently.
The serum is a lightweight liquid containing PHA, designed to target expression lines and skin texture. The cream is a nourishing finishing step, designed to target deeper wrinkles and visible pores.
