Answer
Willow Bark Extract (Natural Salicylic Acid)
Willow Bark Extract, also known as Natural Salicylic Acid, offers several benefits for the skin:
- Exfoliation: It helps accelerate skin cell turnover, similar to synthetic Salicylic Acid, aiding in exfoliation.
- Reduces Irritation: It can help inhibit enzymes related to skin irritation.
- Skin Nourishment: It can help make the skin appear thicker.
- Antioxidant: It provides antioxidant benefits.
- Disinfection: It has effectiveness against various pathogens.
It is effective in reducing dark spots but does not have a skin whitening effect. At a 10% concentration, its exfoliation and acne breakout dissolving properties are comparable to approximately 1.8-2.0% synthetic Salicylic Acid.
Recommended Usage Rate:
- The general usage rate is 1-10%.
- For general skincare, 3% is recommended.
- For accelerated cell turnover and reducing dark spots, 5-10% is recommended.
Mixing Method:
- Mix into the water phase.
- Avoid heat.
- The final formula pH should be between 4.0-6.5.
