What it is
Sandalwood seed extract is a natural ingredient obtained by pressing or extracting the seeds of the Santalum album tree. It contains fatty acids, antioxidants like polyphenols, and unique compounds that differ from the more famous sandalwood essential oil.
How it works
In a cosmetic product, sandalwood seed extract works primarily as an antioxidant, neutralizing free radicals that can cause premature aging. It also has mild anti-inflammatory activity, which can help reduce redness and calm irritation. Its fatty acid content may also support the skin's moisture barrier.
Pros
Gentle antioxidant
Provides antioxidant protection without the irritation potential of some stronger actives, making it suitable for sensitive skin types.
Soothing properties
Helps calm redness and irritation, which can be beneficial for conditions like rosacea or after exfoliation.
Cons and cautions
Less researched
Compared to well-known antioxidants like vitamin C, there is less published research on the specific benefits of sandalwood seed extract in skincare.
Potentially lower potency
While beneficial, its antioxidant activity may be milder than some other plant extracts, so it's often used in combination with other antioxidants.
Best for
- Anyone looking for a gentle, natural antioxidant
- People with sensitive or reactive skin
- Those who want to add soothing ingredients to their routine
Use caution if
- Individuals with a known allergy to sandalwood or related plants (rare)
