Boswellia Sacra resin extract (frankincense) contains boswellic acids and is used in skincare for its anti-inflammatory and soothing properties, and may help calm redness and irritation. It is also valued for fragrance and traditional skin-conditioning uses.
| Reported effect | How often | Notes |
|---|---|---|
| Contact irritation | Uncommon | Mild redness or stinging, particularly in sensitive skin or at higher concentrations. |
| Allergic contact dermatitis | Rare | Sensitization possible, partly due to fragrance and terpene constituents in the resin. |
| Photosensitivity | Very rare | Uncommon reports linked to essential oil/terpene components rather than the extract itself. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
