SkinCare Products Should Not be Mixed

Trying new skincare products is fun, but you can have too many of them, especially if they don’t work well together. You read that right. Some skin care products shouldn’t be used together because they could make your face worse or less effective.

What you put on your face can hurt you more than help, which is one reason you should know what it is. If you want your skin to look healthy and brighter, read about some standard skincare product mixes you should avoid.

Things That Have Powerful Ingredients

To begin, you should only mix more essential items and some poisons with the help of a professional. Some people may get upset when alpha hydroxy acids (AHAs) are mixed with salicylic acid, a beta hydroxy acid. 

Sometimes, it’s okay to mix essential items, but be careful! Taking tretinoin or Retinol by mouth can be used with salicylic acid peeling to make early signs of age look better. But it would help if you only did this with the help of a professional. Don’t try it at home.

Refrain from mixing things on your own, and always test new ones on a small area before using them. Conversely, a dermatologist can help you in a way specific to your skin’s needs.

Several SkinCare Products Should Not be Mixed That All Contain The Same Active Ingredient 

Don’t use two different products that contain the same active ingredient simultaneously. This will help you follow the directions on the ingredients and keep your routine from becoming too repetitive.

SkinCare Products Should Not be Mixed Beta-Carotene And Vitamin C

There are a few things you should think about before using vitamin C and benzoyl peroxide together in your skincare routine. If you mix benzoyl peroxide with antioxidants like vitamin C, the antioxidants may become less effective.

This process of oxidation could make vitamin C useless. Benzoyl peroxide has been shown to lower vitamin E levels in cells by up to 95% and vitamin C levels by up to 70%. Using both ingredients simultaneously might make these vitamins less effective in your skincare practice.

Some people say that vitamin C and benzoyl peroxide shouldn’t be used together, but we suggest doing them at different times to get the best results. For example, you could use one in the morning and the other in the evening. Using them in different ways can help keep any possible interactions to a minimum and let each item do its job.

In the episode of The Science of Beauty show about layering, board-certified dermatologist Marie Jhin from Silicon Valley, California, warned people not to use the two together. People should not use the two products together, she said, because they might make the face red. Remember the last advice: take AHAs in the evening and vitamin C in the morning.

SkinCare Products Should Not be Mixed Only Retinol But Also AHAs

As per research, AHAs and Retinol can both irritate the face.⁴

Because these two strong ingredients can make skin more sensitive, most people with sensitive skin shouldn’t use them in the same skincare routine. Choose kinder combos instead to keep your skin from getting too much.

 There are better ideas than using Retinol and AHAs together. They should be used on different days or parts of your routine. So, your skin will have time to get used to it, and the chance of soreness will decrease.

Remember to put your skin’s health and well-being first, and if you have any questions or worries, talk to a dermatology provider first. 

Use of Retinol and Benzoyl Peroxide 

You should always keep these two vital ingredients together, even though they are both excellent at fighting Acne, because benzoyl peroxide can break down and damage tretinoin, as Chan points out.

 “When mixed, the two ingredients cancel each other out, making both less useful, and the chance of irritation may go up,” says Caroline Robinson, a dermatologist in Chicago.

Robinson and Chan say you should use benzoyl peroxide in the morning and Retinol at night instead. Sticky Acne and marks from Neutrogena make this easy to remember.

Robinson says benzoyl peroxide, or BPO, works well with topical clindamycin, a prescription-only ingredient. Based on Robinson, the two “work synergistically with BPO to combat acne-causing bacteria.

 On the other hand, Retinol works better with products that contain hyaluronic acid, glycerin, and niacinamide because they keep the skin moist, she says.

SkinCare Products Should Not be Mixed Vitamin C and Retinol Together? 

These powerful ingredients may make your skin look brighter and fade dark spots faster than anything else, but they won’t double your glow when used together. Your face will feel very uncomfortable if anything. Chan says that both active ingredients could make your face red and itchy. 

Keep your favourite retinol and vitamin C serums separate to keep your skin from splitting and turning red. She also says you should take vitamin C in the morning because it works better during the day. If you’re looking for a new serum, we have a helpful list of our favourites that are boosted with it. Chan says that Retinol is best for your evening skincare routine because “light can speed up the degradation of the product.

Azadeh Shirazi, a board-certified dermatologist from La Jolla, California, says that kojic acid is the best thing to use instead because it works best when combined with Retinol and vitamin C to make your skin look brighter. The residue of sake is excellent for reducing the look of hyperpigmentation during the day and at night, especially when combined with the serum below.

SkinCare Products Should Not be Mixed Salicylic Acid and Retinol 

Beta hydroxy acids (BHA) are another acid-retinol mix you shouldn’t have. Shirazi says salicylic acid is evil for your face because it is too sharp and dry.

Shirazi also sells niacinamide instead of salicylic acid and Retinol, which can help calm the face by lowering irritation. She says that niacinamide is an excellent way to get rid of Acne because it cleans the skin, stops the skin from making oil, and opens up clogged pores. 

Collagen peptides, which make skin more flexible and firm, are also a good choice instead of salicylic acid because Retinol helps them get deeper into the skin.

 Combining these ingredients doesn’t lead to irritation or over-exfoliation, keeping the skin barrier healthy,” Shirazi says. 

It’s Possible to Mix Vitamin C and Niacinamide.

Yes! A new study says that vitamin C and niacinamide can be used together safely in face care. A study found that stopping melanin production by mixing these two ingredients with something else called PDRN could make the skin lighter.

Always do what the label says, and talk to a dermatologist before adding either product to your face care routine.

Benzoyl Peroxide and Tretinoin: SkinCare Products Should Not be Mixed?


Benzoyl peroxide and tretinoin might only work well if mixed in one bottle. The new study, however, shows that this only sometimes happens. If you take the right amounts, benzoyl peroxide and tretinoin can help treat Acne.

Another way to use them is one at a time, with at least a few minutes between each use. Also, use benzoyl peroxide in the morning and tretinoin at night. Both benzoyl peroxide and tretinoin are generally safe and helpful, but how they work on different people may differ.

Apply Sunscreen, Moisturizer, and Makeup.

People today seek beauty items such as SPF, moisturizers, and makeup. However, this group is one of the most dangerous. You can’t skip steps when using these items. Put each one on its own, and give your face time to absorb them fully. You must put sunscreen on your face and do it again every few hours!

SkinCare Products Should Not be Mixed Niacinamide in Addition to the Anhydrous or Brutally Acidic Acids( AHAs / BHAs)

Niacinamide prevents skin from getting older and redness while also making the skin look brighter.

Like Retinol, Niacinamide shouldn’t be mixed with alpha hydroxy acids, beta hydroxy acids, or vitamin C in skincare items. This is because the mix might be sour on the skin.

When regular niacinamide is mixed with an acid, it can cause a harmful chemical reaction that makes your skin flush and turn red.

Do not use any two products right after each other for at least 30 minutes. Also, take your niacinamide in the morning and your acids at night.

In The Presence of Hydroquinone And Benzoyl Peroxide

Hydroquinone makes the skin lighter and is often used to remove spots. It gets rid of Acne, though, when you use benzoyl peroxide.

You should never mix these two things because they could hurt your skin and make it itch a lot.

Why You Need To Go to a Dermatologist 

So, it’s essential to talk to experts about your skin health! Dermatologists have a lot of training and experience in finding and fixing skin problems. Dermatologists are skin care experts and can make a treatment plan based on your skin type, worries, and medical history. This customized method considers your skin’s sensitivity, reactions, and health issues that may be going on underneath the surface.

Other healthcare workers, like dermatology doctors, can also write prescriptions for medicines you can’t get without one. For some skin problems, these drugs may help, but you should only take them after a doctor has checked them out and given the all-clear. Dermatologists can also keep an eye on your treatment and make any changes that are needed to get the best results.

Knowing what skin care products you shouldn’t mix will help you get the best results and lower your risk of side effects. Before you put something on your skin, always read the directions and do a patch test. Talk to your doctor about the best skin care plan for your skin type and needs. You can make smart choices to get the most out of a complete skincare routine and keep your skin healthy and beautiful.
