A combination of L-ascorbic acid (vitamin C), an antioxidant that supports collagen synthesis and brightens skin, and hyaluronic acid, a humectant that binds water to hydrate and plump the skin. The pairing aims to deliver antioxidant benefits while offsetting the potential drying or irritating effects of vitamin C.
| Reported effect | How often | Notes |
|---|---|---|
| Mild stinging or tingling on application | Common | Often transient and linked to the low pH required for ascorbic acid stability. |
| Skin irritation, redness or dryness | Uncommon | More likely at higher ascorbic acid concentrations or on sensitive skin. |
| Contact dermatitis or allergic reaction | Rare | May relate to formulation components rather than the actives themselves. |
| Yellowing or temporary skin discoloration | Rare | Associated with oxidized ascorbic acid in degraded formulations. |
