Understanding which skincare ingredients can be combined and which should be avoided is crucial for maintaining healthy skin and preventing irritation.
Ingredients That Should Not Be Mixed
Vitamin C:
- Do Not Mix With: Retinol, Niacinamide, AHA/BHA, Peptides, Benzoyl Peroxide
- Reason: Can be too strong and cause irritation. Vitamin C is acidic and can destabilize when combined with certain ingredients, reducing its effectiveness.
Retinol:
- Do Not Mix With: Vitamin C, AHA/BHA, Benzoyl Peroxide, Salicylic Acid, SPF, UV Light
- Reason: Can cause severe skin irritation and diminish the effectiveness of SPF. Retinol increases skin sensitivity, especially to UV light, and can lead to increased irritation when mixed with other strong actives.
AHA/BHA:
- Do Not Mix With: Retinol, Vitamin C, Niacinamide, Benzoyl Peroxide
- Reason: These combinations can lead to excessive skin irritation and sensitivity. AHAs and BHAs exfoliate the skin, which can be too much when combined with other potent actives.
Niacinamide:
- Do Not Mix With: Vitamin C, AHA/BHA
- Reason: Can neutralize each other's effectiveness. Niacinamide and Vitamin C can cancel out each other's benefits, and combining Niacinamide with strong exfoliants like AHA/BHA can lead to irritation.
Glycolic Acid and Salicylic Acid:
- Reason: The combination can be too drying and irritating for the skin. Both are strong exfoliants, and using them together can over-exfoliate the skin, causing dryness and irritation.
