Matmarine is a marine-derived biotechnological ingredient (sourced from a cold-marine bacterium) used to reduce sebum production and mattify oily or shine-prone skin. It is typically incorporated into formulations targeting excess oiliness and enlarged pores.
| Reported effect | How often | Notes |
|---|---|---|
| Mild transient irritation or redness | Rare | Generally well tolerated; occasional sensitivity reported in susceptible individuals. |
| Contact dermatitis or allergic reaction | Very rare | Isolated cases possible, as with most cosmetic ingredients; patch testing advised for sensitive skin. |
| Skin dryness or tightness | Uncommon | May occur with overuse in already dry skin types due to sebum reduction. |
