What it is
An extract derived from the buds of the hazel tree (Corylus avellana), containing natural compounds like flavonoids and tannins that have antioxidant and soothing potential.
How it works
The flavonoids in hazel bud extract help neutralize free radicals, which are unstable molecules that can damage skin cells. Its tannins may provide a mild astringent effect, helping to tighten pores and calm irritation. In a formula, it works alongside other ingredients to support the skin's natural defense system.
Pros
Gentle on skin
Unlikely to cause irritation, making it suitable for sensitive skin types and those new to antioxidants.
Natural antioxidant
Provides a plant-based way to fight free radicals, which can help prevent premature aging from environmental stressors.
Cons and cautions
Limited research
Most evidence comes from lab studies, not large human trials, so its real-world benefits are not as well-documented as more common antioxidants.
Potential allergen
Though rare, people with tree nut allergies may experience a reaction; a patch test is recommended before widespread use.
Best for
- People with sensitive or reactive skin looking for a mild antioxidant
- Anyone wanting to add a gentle, plant-based soothing ingredient to their routine
Use caution if
- Individuals with a known allergy to hazelnuts or tree nuts should patch test first or consult a dermatologist
