P-TIOX is designed to mimic the mechanism of neurotoxin injections by using peptides that interfere with the neuromuscular communication that causes repetitive contraction lines. It is not as powerful as an injectable, but it targets nine types of expression lines including forehead lines, crow's feet and lines around the mouth that neurotoxins often cannot fully address. SkinCeuticals specifically position it as a complement to, and a stand-alone alternative to, injectable neurotoxins.

C E Ferulic is backed by more independent peer-reviewed research than almost any other topical skincare product. The specific ratio of 15% L-ascorbic acid, 1% vitamin E and 0.5% ferulic acid is patented and has been shown to provide eight times the photoprotection of vitamin C alone. The formula has been essentially unchanged for over 20 years because it does not need to be.

C E Ferulic is generally considered safe during pregnancy. P-TIOX contains salicylic acid and alcohol, so we recommend checking with Dr Laura or your midwife before use during pregnancy. The set is not recommended as a whole during pregnancy.
