What it is
Red sandalwood extract is a natural ingredient derived from the stem (heartwood) of Pterocarpus santalinus, a tree known for its deep red wood. It contains compounds like santalins and flavonoids that give it antioxidant and anti-inflammatory properties.
How it works
The extract works by providing antioxidant compounds that neutralize free radicals, potentially reducing oxidative stress on the skin. Its anti-inflammatory components may help calm redness and irritation when applied topically.
Pros
Gentle soothing potential
Traditional use and some lab studies suggest it can help calm redness and irritation, making it a good option for sensitive skin types.
Antioxidant support
Contains flavonoids that may help protect skin from free radical damage caused by UV and pollution, though more human research is needed.
Cons and cautions
Limited human evidence
Most research is lab-based or traditional; there are few well-controlled human studies confirming its benefits in modern skincare.
Potential allergen
Though rare, some people may experience allergic contact dermatitis, so a patch test is wise before regular use.
Best for
- People with sensitive or easily irritated skin looking for a gentle soothing ingredient
- Anyone wanting to add a natural antioxidant to their routine
Use caution if
- Individuals with known allergies to sandalwood or related plants should patch test first
