Nowadays, more and more people have sensitive skin. They like a brand of products but are afraid of having allergies after using them. What to do? You can do an allergy test first. Especially for sensitive skin, try to do an allergy test when using cosmetics. So, how to do cosmetic allergy testing?

How to do cosmetic allergy test

There are four ways to test whether cosmetics cause allergies. One is to read the instructions, two is to apply it behind the ears, three is to rub it on the arms, and four is to apply it on other parts of the body. If there is no special reaction after waiting for a period of time, it proves that there is no allergy. If you feel uncomfortable, you should not use this cosmetic. Specific examples include:

1. Read the instructions: If you have a history of allergies, you must remember what the allergens are. Before using the cosmetics you want, you can check the instructions to see if there are any allergens. If there are, you cannot use it.

2. Apply behind the ear: Apply behind the ear. The skin in the depression behind the earlobe is very close to the facial skin. You can apply a little cosmetics to this place and wait for dozens of minutes. If there is no allergic reaction, you can use it on your face.

3. Rub on the arm: Soak a small piece of gauze with distilled water or saline, dip it in some cosmetics, and then apply the gauze to the normal skin of the arm, fix it with plastic wrap and tape, wait for a day or two, if there is no reaction, it means there is no allergy, if you feel tingling or itching, stop using it. If simple erythema and itching are present, it is weakly positive; if redness, swelling and papules are present, it is moderately positive; if obvious redness, swelling, papules and blisters are present, it is strongly positive; if obvious blisters and even necrosis are present, it is extremely strongly positive. If a positive reaction occurs, in addition to timely cleaning and disposal, it is also recommended that the cosmetics must not be used at all.

4. Apply to other parts of the body: Apply cosmetics to the legs, back and other parts to test for allergies. Sometimes when the skin is inflamed, temporary allergies may occur, and the cosmetics need to be applied to other parts to test the effects.

How to reduce the damage of makeup to the skin

1. Maintenance work before makeup

The maintenance methods for dry skin, oily skin and combination skin are different. You should choose the appropriate maintenance method according to your specific skin condition. The main steps are cleansing + toner + eye cream + essence + cream, and then apply isolation cream.

2. Choice of cosmetics

Some ingredients in makeup can easily cause skin problems. In addition to reading the instructions, try the product before buying or choose the product according to your skin type. People with oily skin should avoid choosing greasy and heavy cosmetics, because oily skin has strong oil secretion and its pores are prone to enlargement. The oil in cosmetics will absorb dust in the air, which is more likely to cause skin pores to be blocked and cause the growth of acne.

3. Take breaks when applying makeup

Give your skin a rest, as endless accumulation of cosmetics will damage your skin. Therefore, you should give your skin a proper rest. For example, don't wear makeup when you are not going out. Just do basic skin care.

4. Do a good job of cleaning

Makeup will not harm your skin. The real reason for skin damage is not doing a good job of cleaning. Choosing the right makeup remover is of utmost importance.

5. Don’t wear heavy makeup

In daily life, it is better to wear light makeup. Heavy makeup will not only make people look weird, but also inhibit the skin from "breathing" smoothly.
