A potent 23% vitamin C serum that customers praise for brightening, hydrating, and clearing skin. Shoppers noted it "absorbs well" and is "lightweight" for oily/combination skin. However, the strong vitamin C scent bothers some, and the formula oxidizes quickly, requiring refrigeration. Overall, customers found it effective for redness and spots at great value.

  • Packs a mighty punch. Keeps my complexion clear and smooth. Powerful and very effective.
  • Found a vitamin C that works for my skin. Really helped with my redness.
  • Really hydrating, sits nicely on my skin and plays nicely with other products.

Really hydrating vitamin c

Really hydrating vitamin c, haven’t been using it that long but it sits nicely on my skin and plays nicely with other products. It does have the typical vitamin c smell, but it is gentle and doesn’t irritate my skin

Great lightweight serum

Lightweight serum that’s perfect for my oily/combination skin. The finish is sticky but the stickiness goes away when paired with moisturizer. The packaging gives a luxurious feel too.

Oxidises quickly, needs to be refrigerated when not in use. Slightly greasy but fades spots well.
