Paula’s Choice built a reputation on unpretty bottles and ingredient lists that do not wink. The C15 Super Booster is a lightweight vitamin C serum aimed at dullness, uneven tone, and the look of fine lines. It is a booster by design: a few drops mixed into moisturiser or worn under it, not a ceremony.
L-ascorbic acid at a meaningful percentage, supported by vitamin E and ferulic-style antioxidant thinking, is the classic brightening trio for a reason. The texture is the point of this one — thin enough that people who hate sticky C serums will finish the bottle. Use it in the morning. Wear SPF. Expect weeks, not a weekend.
Vitamin C is not a glow in a week. It is a daily antioxidant that asks for sunscreen and patience.
Who it is for
Dull, uneven, sun-tired skin that can tolerate a low-pH acid. Not for a barrier that is already peeling, and not a substitute for a retinoid if lines are your only concern. If C serums have oxidised on you before — turning orange, turning useless — buy a small size, keep it away from heat, and finish it. Paula’s Choice is rarely the most romantic bottle on the shelf. It is often the one you empty.
Pair it with the beginner’s routine elsewhere in this issue: cleanse, moisturise, this, then sun. If you already love Beauty of Joseon’s Glow Serum, you may not need both. If you want a more clinical C, C15 is the quieter, less viral answer — and, for many faces, the better one.
