Ingredients you should NOT mix

"Ever wondered why your skin is sensitive after trying a bunch of skincare products at the same time?"
Ingredients you should NOT mix

Cristina López Saucedo - Mar 29, 2022

Usually, in our daily skincare routine, we mix ingredients to potentiate the effects, and of course, it makes perfect sense. But when doing this we have to keep in mind that there are ingredients that when mixed instead of benefiting, it could damage your skin.

Therefore, here are some of the most common erroneous combinations:

Retinol + AHA / BHA

Retinol works by improving cell turnover, increasing collagen production, and improving the appearance of fine lines and wrinkles, but it can be sensitizing to the skin.

AHA/BHA containing glycolic acid, lactic acid, or salicylic acid can exfoliate and produce a more even skin tone, but when combined with an anti-aging ingredient like retinol, it can cause painful flaking in someone with sensitive skin.

When using products with retinol, the ideal would be to combine it with a moisturizer to reduce sensitization and enhance hydration.

Retinol + Vitamin C

Vitamin C is an antioxidant and environmental protector that works best during the day in combination is best used during the day.

On the other hand, Retinol works as correctors that are inactivated by sunlight, so combining them can generate an opposing effect.

The best way to "combine" these ingredients and take full advantage of their benefits is to use vitamin C during the day and retinol at night.

Vitamin C + AHAs / BHAs

Vitamin C is an acid, so combining it with AHAs and BHAs, such as glycolic, salicylic, and lactic acid, can be very irritating, as any layered acid has the superpower to unbalance the pH. If you want to use both in your day, make sure they are separate: vitamin C in the morning and AHAs and BHAs at night. oh!


And don't forget your SPF!
