These Skincare Products Should Not Be Mixed
Having a skincare routine is essential for maintaining healthy, glowing skin. But with so many products on the market, it can be confusing to know which ones to use and how to layer them. One question that often comes up is whether or not it's safe to mix skincare products.
The answer is that it depends on the ingredients in the products. Some ingredients can interact with each other in a negative way, causing irritation, dryness, or other skin problems. For example, mixing a retinol product with a vitamin C product can be too harsh for the skin.
Here are some general guidelines to follow when mixing skincare products:
-
Start with gentle products. If you're new to mixing skincare products, it's best to start with gentle, fragrance-free formulas.
-
Introduce new products one at a time. This will help you identify any products that might be causing irritation.
-
Pay attention to the pH of your products. Skincare products have a pH level, which is a measure of how acidic or alkaline they are. It's generally best to use products with a similar pH level together.
-
Be mindful of active ingredients. Some active ingredients, such as retinol and vitamin C, can be irritating if not used correctly.
Skincare Product Combinations to Avoid
1. Retinol and Vitamin C
Why Avoid It:
Retinol and Vitamin C have different pH requirements for optimal effectiveness. Combining them can reduce their efficacy and cause irritation, especially for sensitive skin.
What to Do Instead:
Use Vitamin C in your morning skincare routine and retinol at night.
2. Retinol and AHAs/BHAs
Why Avoid It:
Both retinol and exfoliating acids like glycolic or salicylic acid can increase skin sensitivity. When used together, they may cause redness, peeling, or breakouts.
What to Do Instead:
Alternate between retinol and exfoliating acids on different nights.
3. Benzoyl Peroxide and Retinol
Why Avoid It:
Benzoyl peroxide can deactivate retinol, reducing its benefits. Additionally, using both together can cause extreme dryness or irritation.
What to Do Instead:
Use benzoyl peroxide in the morning and retinol at night.
4. Vitamin C and AHAs/BHAs
Why Avoid It:
Mixing Vitamin C with acids can destabilize the Vitamin C, reducing its effectiveness and potentially irritating your skin.
What to Do Instead:
Apply acids at night and Vitamin C in the morning for better results.
5. Niacinamide and Vitamin C
Why Avoid It:
Although newer formulations are less reactive, mixing older versions of niacinamide and Vitamin C can cancel out their benefits and cause skin irritation.
What to Do Instead:
Layer them with a time gap or use one in the morning and the other at night.
6. Sunscreen and Makeup Primers with Oils
Why Avoid It:
Oil-based primers can break down sunscreen, reducing its protective effects.
What to Do Instead:
Apply sunscreen first, let it set, and then use a non-oil-based primer.
7. Hyaluronic Acid and Drying Alcohols
Why Avoid It:
Drying alcohols counteract the hydrating effects of hyaluronic acid, leaving skin dehydrated.
What to Do Instead:
Check product ingredients to avoid alcohol-based products when using hyaluronic acid.
8. Peptides and AHAs/BHAs
Why Avoid It:
Acids can break down peptides, making them less effective in improving skin texture and firmness.
What to Do Instead:
Use peptides in a separate routine from exfoliating acids.
9. Physical Exfoliants and Chemical Exfoliants
Why Avoid It:
Using scrubs with acids can over-exfoliate the skin, leading to sensitivity, redness, and breakouts.
What to Do Instead:
Stick to one type of exfoliant at a time and use it 2–3 times a week.
10. Fragrance-Heavy Products and Active Ingredients
Why Avoid It:
Fragrances can irritate the skin when combined with active ingredients like retinol or acids.
What to Do Instead:
Choose fragrance-free skincare products when using actives.
