Acnacidol BG is a biotechnology-derived active (10-hydroxydecanoic acid produced via fermentation, in a butylene glycol base) used to target acne by regulating sebum production and inhibiting the proliferation of Cutibacterium acnes. It is marketed as a gentler alternative to harsher anti-acne agents for blemish-prone skin.

| Mild localized irritation or redness | Rare | Generally well tolerated; transient irritation possible in sensitive individuals. |
| Contact sensitization or allergic reaction | Very rare | Isolated potential, as with most cosmetic actives; patch testing advised for reactive skin. |
| Dryness | Rare | Possible with combined use of other drying anti-acne agents. |
