Which skin care products can't be mixed and which ingredients can't be superimposed.

Different skin care products have different effects. Many people like to buy different brands of skin care products. Mixed use of skin care products is a very common way of skin care, but some skin care products mixed on the face will cause harm.

Which skin care products should not be mixed?

1, components that will react chemically should not be mixed together.

A. Two components with different pH orientations cannot be superimposed.

B, skin rejuvenation products containing A acid should avoid mixing with gel frozen film products, which will offset the former.

C. Avoid using products containing salicylic acid, ethanol and vitamin A, which will cause excessive exfoliation and sensitivity.

2. The skin care steps of different products are repetitive and cannot be mixed.

Japanese products and European skin care products are very different, and they can be mixed and mixed, but it is necessary to ensure that the mixed products must not cause repeated skin care steps. Because it is easy to cause excessive cleaning, after the cuticle is injured, the skin loses a natural "screen door".

In fact, most European brands use facial cleanser+emulsion to complete the cleaning step, and its water has the ability of secondary cleaning, while most Japanese brands are cleansing oil+facial cleanser, and the emulsion is only responsible for hydrating and moisturizing. If you used cleansing oil+facial cleanser at first, this facial cleanser already has the function of deep cleaning, but later you changed to another lotion with the function of cleaning the cortex, which is equivalent to three times the effort.

3. Products with overloaded functions should not be mixed and matched.

No matter which brand the products with similar efficacy belong to, their nutritional components and working principles are similar, and the main brands of most brands contain high concentrations of ingredients. Therefore, when products with similar efficacy are mixed, the only function is to make the nutrition surplus due to the superposition of functions, and because of the limited absorption capacity of the skin, it can only cause the waste of nutrition and even cause skin rejection.

4. Deep cleaning and exfoliating products must not be used at the same time.

Deep cleaning products can not only clean pore garbage, but also clean waste keratin. Exfoliating products are the best choice to remove waste keratin. Never use two products with the same exfoliating function together. It is best to use them once every two weeks.

5, can't use a variety of "acidic" skin care products at the same time.

The main function of acidic ingredients is also exfoliation, so you can't use skin care products containing acidic ingredients unless you don't do extra exfoliation care at ordinary times and the skin care products contain less acid.

6. Don't superimpose too much essence.

As the saying goes, essence is concentrated, so the nutrition of essence is still very high. Therefore, unless your skin has aged to the point where it needs a lot of nutritional supplements, you can't use different essences in your usual care. Even if you have such skin needs, you should use it in the morning and evening. Everything is too much, too much essence is used, which can't be absorbed by the skin, so it's still a waste!

Which ingredients must not be superimposed?

1, high concentration nicotinamide, and it is not recommended to overlap with fruit acid (AHA), salicylic acid and high concentration VC;

2. It is not recommended to superimpose fruit acid (AHA) and vitamin A alcohol (retinol) on salicylic acid products. Because peeling is too strong, it is easy to damage the skin.

You should use essence or other skin care products, and don't fold for the sake of folding. You don't have to do a full set of skin care steps. Only two or three products can do a good job of cleaning, moisturizing and sun protection, and sun protection is also the most effective anti-oxidation means.

Can nicotinamide essence be superimposed with nicotinamide cream?

For example, a set of Olay, white bottle essence+red bottle cream can be superimposed as long as the skin is tolerant.

Can nicotinamide and hyaluronic acid be used together?

? Nicotinamide and hyaluronic acid can be used together. Nicotinamide is used for skin whitening, and hyaluronic acid is used for hydrating and moisturizing. In terms of efficacy, nicotinamide and hyaluronic acid have their own functions and can be used together without affecting their efficacy.
