Milk lipids are fatty components derived from milk used in skincare to soften skin, reinforce the lipid barrier, and improve moisture retention. They function primarily as conditioning emollients rather than treatment actives.
| Reported effect | How often | Notes |
|---|---|---|
| Contact irritation or redness | Uncommon | Mild transient irritation possible, especially on sensitive skin. |
| Allergic contact dermatitis | Rare | May occur in individuals sensitized to milk proteins or residual components. |
| Acneiform breakouts/comedogenicity | Uncommon | Some lipid-rich formulations may clog pores in acne-prone skin. |
| Hypersensitivity in milk-allergic individuals | Very rare | Potential reaction if dairy-derived protein residues remain in the lipid fraction. |
