"Improves elasticity" describes ingredients (such as peptides, retinoids, vitamin C, or hyaluronic acid) that support skin's ability to stretch and recoil, typically by promoting collagen and elastin production or improving hydration. The specific side effect profile depends on the active compound used.
| Reported effect | How often | Notes |
|---|---|---|
Mild irritation or stinging | Common | Often seen with retinoids or acids, usually transient during initial use |
Dryness or peeling | Common | Particularly with retinoid-based actives |
Redness (erythema) | Uncommon | More likely with higher concentrations or sensitive skin |
Contact dermatitis | Rare | Allergic or irritant reaction to specific formulation components |
Photosensitivity | Rare | Notably with retinoids and some vitamin C derivatives; sunscreen advised |
Severe allergic reaction | Very rare | Hypersensitivity requiring discontinuation |
