P-TIOX Anti-Wrinkle Serum
SUMMARY OF REVIEWS
SkinCeuticals P-TIOX Anti-Wrinkle Serum contains an advanced peptide complex including hexapeptide-8, a common ingredient in cheaper products. Board-certified dermatologist Dr. Sarah Sheu notes clinical testing showed a 20% reduction in fine lines after 12 weeks, but cautions that this translates to a subtle visible difference in person. At $150 for 30 ml, she leaves the value judgment to the buyer.
