A Guide of Skincare Ingredients you should not Mix

When it comes to skincare, less is more–meaning the lesser products you use the better. There are a lot of skincare ingredients that our skin can benefit from, we often heard trending ingredients that we want to try.
However, did you know that there are some ingredients that shouldn’t be used at the same time? Using them together can cause harm to your skin, it can cause dryness, irritation, redness, and breakouts.
So, here’s a guide of what ingredients you should not mix!
AHA/BHA and Vitamin C
Vitamin C is a very powerful anti-oxidant and may doesn't know that it is also an Acid. So, combining it with AHA and BHA that's also an acid can be really irritating for your skin. It makes one another ineffective too. If you want to use both of them use in the morning Vitamin C them AHA/BHA at night.

Glycolic Acid and Salicylic Acid

Never a good idea to combine these two. It will lead to a damaged skin barrier and really dry skin that can lead to skin irritation. Only use one of these and follow up with a hydrating product.

Retinol and Benzoyl Peroxide

Did you know that using both of them can deactivate each other? So never use these 2 together. It’ll be just a waste of money.

AHA/BHA and Niacinamide

Niacinamide or Vitamin B is an excellent repairing ingredient however, it requires a neutral pH to be effective. Using niacinamide with any AHA/BHA has no effect and can actually cause redness. So use them separately to enjoy their benefits on your skin.

Vitamin C and Benzoyl Peroxide

Vitamin C should be used alone and shouldn’t be mixed with other acids. Benzoyl Peroxide is an aggressive ingredient that can exfoliate and dry your skin, so using it together with another acid can definitely dry and irritate your skin.

Retinol and Vitamin C

They are both active ingredients which is not a good idea of using them together. Retinol helps build collagen and also creates skin turnover so if you use it with acid can cause more irritation.

Benzoyl Peroxide and Hydroquinone

These ingredients have a lightening effect on your skin and both can be irritating. Using it together can make your skin more sensitive to the sun causing more sun damage, spots, and acne. That’s why never use these 2 together!
