The Skincare Ingredients You Should Never Mix Together

The Skincare Ingredients You Should Never Mix Together

Skincare overload?

Ever had a fish tank and kept on feeding them, to then realize the fish were getting sick and the water cloudy?

Yes, were thinking on doing something good for them but it turns out that too much is too much. Less is more!

The same is true for our skin and the use of skincare products.

We all have listened to the famous phrase, “excess of everything is bad”, but in the case of skincare products there is an even more famous saying, “if a little is good, then more is better”.

This is making skin-care junkies go on an unquenchable hunt for every next so-called must-have beauty products.

But what might shock them is the revelation that even the best and most expensive of these products which are considered safe otherwise could backfire if used in excess or when mixed with other products. 

There are multiple reactions to this overdoing and mixing products. These can counteract each other's actions and may lead to inflamed skin, rashes, itching, or sun-sensitive skin.

A board-certified dermatologist Dr. Shari Marchbein says that mixing different skincare products without understanding the work and interaction will cause a waste of money, time, and potential skin problems.

Plus, it will add to the frustration if expected results will not be gained.

Balance is the key:

Sometimes adding products together can help you in some way, like adding a face oil under your moisturizer is a good thing. But in other cases, balance upset occurs leading to one of two fates; either all the product is sitting up on top of your skin giving oily look, or it is red and irritated. 


By applying layer after layer of products before the last or to sink or absorb properly can lead to makeup/product pilling. For example, when you apply some serum or moisturizer and then apply another skin treatment before these two can sink in or get dry can lead to pilling. Applying more than your skin needs also leads to the same result. Too much amount of product building up on the skin can cause this pilling. 

Do not Use these Ingredients Together: 

Although there is a long list of ingredients that are being told as the best and the safest for the skin, there are certainly many cases when a combination of such ingredients is the problem and the following are the ingredients that aren't to be used together.

  1. Vitamin C with Benzoyl Peroxide, Copper peptides:

Vitamin C is often found in light and airtight packaging because it loses its potency when oxidized. While on the other hand benzoyl peroxide, a strong anti-acne treatment ingredient is a strong oxidizing agent and the use of these two together will not give the full result as expected. 
Both vitamin C and copper peptides have a lot of benefits with making collagen and acting as anti-aging in common. So, generally, it is thought that mixing them would give extra benefits of an anti-aging cocktail, but the scenario is different because vitamin C becomes unstable with copper peptides and the mixture is useless.

  1. Retinol with Benzoyl Peroxide, Vitamin C, and AHA/BHA Acids:

Dr. Shari Marchbein explains that the use of retinol with benzoyl peroxide will literally nullify the effect of each of these products and you will not get anything out of this mixture. 

Similarly, vitamin C, a skin protector, and retinol, a skin repairer are best used at different times of the day with vitamin C at daytime and retinol overnight. 

AHA/BHA acids are exfoliators and add to the dryness of skin if used with retinol. It can, sometimes, lead to irritation, redness, and even eczema.

  1. Salicylic Acid with Glycolic Acid:

Salicylic acid most commonly used to unclog pore is an anti-acne ingredient. Glycolic acid on the other hand, for its resurfacing properties, is an anti-aging ingredient. Overuse of these exfoliators together can cause negative and harmful effects on skin reacting in a rash-like manner, becoming flaky, irritated, and red. 

What add to the insult is that people often tend to kill the reaction of using these mixtures by applying some other product. But the best way is to stop using all the regimens and understanding what’s best for your skin. And never hesitate to go to a dermatologist, if all else fails.
