What is Paula's Choice C15 Super Booster?
Paula C15 Super Booster carries 18 ingredients on its published label. We read the list in order, because above roughly one percent ingredients are listed in descending order of concentration, which is the only public signal of dose when a brand does not publish percentages. The preservative system starts at position 18, so everything after it is present in small amounts.
Key ingredients
What the hero actives in C15 Super Booster are supposed to do.
L-Ascorbic Acid (Vitamin C)
Position 2 on the list. The biologically active, unesterified form of vitamin C, a potent water-soluble antioxidant that neutralizes UV/pollution free radicals, is an essential cofactor for collagen synthesis, and brightens pigmentation. Powerful but notoriously unstable.
Bisabolol
Position 10 on the list. A monocyclic sesquiterpene alcohol from German chamomile (its natural source) that calms skin by suppressing pro-inflammatory signaling, making it a classic soothing additive for sensitive and reactive skin. It is very well tolerated.
Ferulic Acid
Position 11 on the list. A plant-derived phenolic-acid antioxidant whose signature role is stabilizing and roughly doubling the photoprotective power of a vitamin C + vitamin E serum (the classic "CE Ferulic" combo). Safety 9/10 (safe).
Tocopherol (Vitamin E)
Position 14 on the list. The lipid-soluble antioxidant vitamin, a chain-breaking radical scavenger that protects skin-cell membranes and the stratum-corneum lipids from oxidation, and (crucially) stabilizes and regenerates vitamin C. Safety 9/10 (safe).
