How to test whether you are allergic to cosmetics

Skin care products are very common in daily life. Most women use them almost every day. We all know that if you have sensitive skin, improper use of cosmetics can easily lead to allergies. In fact, when you buy cosmetics, you can try them first to see if you have any other discomfort in your body. If not, it is generally not an allergy. If there is any abnormality, it is best not to use it.

How to test for cosmetic allergies

The method for skin allergy test of cosmetics is very simple. First, soak a piece of gauze with distilled water or saline, wring it until half dry, and fold it into 4 layers of about 1 square centimeter. Apply the cosmetics on one side of the gauze, and then apply it on the extensor side of the forearm or the normal skin of the back, then cover it with 1.5 square centimeters of airtight cellophane or plastic film and fix it with tape.

After 24 to 48 hours of observation, if the test area is severely itchy or burning, it indicates that the cosmetic is irritating to the skin. This is a positive reaction and the test object should be removed promptly and rinsed with clean water. If there are no symptoms at the test site, it is a negative reaction, indicating that the cosmetic is non-irritating to the skin and is relatively safe.

If simple erythema and itching appear, it is weakly positive; if redness, swelling and papules appear, it is moderately positive; if significant redness, swelling, papules and blisters appear, it is strongly positive; if significant blisters or even necrosis appear, it is extremely strongly positive. If a positive reaction occurs, in addition to timely cleaning and treatment, it is also recommended that the cosmetics must never be used.

What are the symptoms of cosmetic allergy?

The symptom of cosmetic allergy is itching, which may also be accompanied by redness, swelling, dry scales, blisters, or scabs and exudate liquefaction of lesions; these lesions vary in shape and size. Occasionally, symptoms such as chest tightness, numbness, and swelling may occur; when these symptoms occur, it is a skin allergy.

Skin allergies are directly related to the irritants in the cosmetics used or the thin stratum corneum of the skin.

At the same time, it is important to note that once the skin is allergic, do not eat spicy or irritating foods, wear sunscreen, do not use irritating cosmetics, and stay away from computer radiation. Desensitizing skin care products using plant ingredients are gentle and non-irritating to the skin. They can also replenish moisture and nutrients for the skin and repair damaged skin.

What to do if you are allergic to cosmetics

The reason for cosmetic allergies is that the skin's stratum corneum is thin, which makes it more sensitive to the substances in cosmetics and causes allergies. First, stop using cosmetics, cleanse your face with warm water, and wipe it with a facial cotton.

Secondly, use the computer less often because the skin is more fragile due to allergies caused by cosmetics and is more sensitive to external stimuli.

Then, aloe vera is the best choice to solve skin cosmetic allergies. Put the aloe vera in a container and mash it into a paste with a tool, then spread it evenly on the gauze.

Finally, apply it on your face after cleansing, leave it on for 10 minutes, then cleanse. Once a week is enough.
