1. Do not use physical (manually scrubbing or using a tool) and chemical exfoliants (mild acids or enzymes) at the same time
- This puts you at risk for over exfoliating, which causes microscopic tear
2). Avoid using acne treatments (benzoyl peroxide) and chemical exfoliants (AHA & BHA) at the same time
- Irritates your skin
- Builds up tolerance to ingredients
3). Avoid using vitamin C with AHA, BHA and benzoyl peroxide
- AHA/BHA --> exfoliants
- Disrupts pH balance (optimal level is 5)
- Disrupts effectiveness of vitamin C
- Vitamin C works well with Vitamin E
4). Use hyaluronic acid before face oils
- Apply products from light consistency to oily the lighter consistency usually absorbs better
- Using oils first blocks the hyaluronic acid from being absorbed into the skin
