When it comes to skin care, it is important to know which ingredients should not be used together.
While some ingredients can be beneficial when used together, others can be harmful and can even cause irritation and inflammation. Here are six skin-care ingredient combinations that should not be used together:
1. Retinoid or Retinol and Alpha Hydroxy Acid: Retinoids and alpha hydroxy acids (AHAs) are both powerful exfoliants, but using them together can be too harsh on the skin. The combination can cause irritation, redness, and dryness.
2. Retinoid or Retinol and Benzoyl Peroxide: Retinoids and benzoyl peroxide are both used to treat acne, but using them together can be too harsh on the skin. The combination can cause redness, dryness, and irritation.
3. Retinoid or Retinol and Vitamin C: Retinoids and vitamin C are both antioxidants, but using them together can be too harsh on the skin. The combination can cause redness, dryness, and irritation.
4. Retinoid or Retinol and Salicylic Acid: Retinoids and salicylic acid are both used to treat acne, but using them together can be too harsh on the skin. The combination can cause redness, dryness, and irritation.
5. Soap-Based Cleanser and Vitamin C: Soap-based cleansers can strip the skin of its natural oils, while vitamin C can be too harsh on the skin. The combination can cause redness, dryness, and irritation.
6. Two Products With the Same Actives: Using two products with the same active ingredients can be too harsh on the skin. The combination can cause redness, dryness, and irritation.
