Evidence-Based Natural Ingredients
Alpha Hydroxy Acids from Natural Sources:
Lactic Acid from Dairy Products: Lactic acid occurs naturally in fermented dairy and provides gentle exfoliation with hydrating properties.
Scientific evidence:
- Studies show 5-12% lactic acid improves skin texture
- Gentler than synthetic glycolic acid
- Provides both exfoliation and moisturization
- Safe for daily use at lower concentrations
How to use:

- Buttermilk compresses: Soak cloth and apply to affected areas
- Frequency: 3-4 times weekly initially, daily as tolerated
Citric Acid from Lemons: Citric acid provides natural exfoliation but requires careful use to avoid irritation.
Application method:
- Fresh lemon juice diluted 1:1 with water
- Apply with cotton pad, leave 10 minutes maximum
- Always rinse thoroughly and moisturize
- Use only in evening due to photosensitivity
Important precautions:
- Can cause irritation and increase sun sensitivity
- Test on small area first
