Makeup allergies are related to individual constitution and factors such as the quality of cosmetics. It is necessary to treat them according to different causes. Allergies are common, but they often recur. Early treatment is needed to prevent worsening of allergy symptoms.
[How to test cosmetics for sensitive skin]
1. Characteristics of sensitive skin
Sensitive skin has a thinner stratum corneum, prominent red blood vessels on the face, easily turns red, is easily affected by heat and cold, and easily gets sunburned. The influence of an unreasonable diet or external environment on this type of skin is significant, and it is prone to stinging, redness, itching, and other problems. Improper use or overuse of skincare products is also the main cause of sensitive skin.
2. Precautions for using cosmetics on sensitive skin
Generally, sensitive skin needs to be treated according to the severity. Mildly sensitive skin only needs to choose cosmetics specifically for sensitive skin and make appropriate changes in lifestyle based on using cosmetics correctly. How to test cosmetics for sensitive skin
3. Methods for testing cosmetics for skin allergies
The method for testing skin allergies to cosmetics is very simple. First, soak a piece of gauze in distilled water or saline, wring it out until it is semi-dry, and fold it into 4 layers about 1 square centimeter in size. Apply the cosmetics on one side of the gauze and then apply it to the normal skin on the inner arm or back, and cover it with 1.5 square centimeters of non-permeable glass paper or plastic film, fixed with adhesive tape.
After 24-48 hours of observation, if the test area is severely itchy or painful, indicating that the cosmetics are irritating to the skin, it is a positive reaction, and the test substance should be removed promptly and rinsed with water. If there are no symptoms in the test area, it is a negative reaction, indicating that the cosmetics are not irritating to the skin and relatively safe. If there is only a simple erythema and itching, it is a weak positive reaction; if there is redness, papules, it is a moderate positive reaction; if there is significant redness, papules, and vesicles, it is a strong positive reaction; if there are significant vesicles or even necrosis, it is a very strong positive reaction. If a positive reaction occurs, the cosmetics should not be used under any circumstances, and they should be washed off and disposed of immediately.
[How makeup affects the skin]
1. Formation of acne
Daily makeup needs to be done correctly. For example, improper techniques or excessive force can easily damage the surface of the skin, causing foundation and other makeup products to block pores and affect the normal metabolism of the skin, leading to the formation of acne and blackheads.

2. Increased skin sensitivity
For skin that is already fragile, frequent makeup and the use of a large amount of cosmetics can easily make the skin's stratum corneum fragile and more sensitive.
3. Skin damage
Many cosmetics contain certain metal chemical components, which can cause significant damage to the skin. Long-term use can easily lead to skin damage, causing the skin to become dull and rough, and promoting premature aging and the formation of wrinkles.
4. Various adverse reactions
Accumulation in the body can cause various adverse reactions, especially in the central nervous system, such as insomnia, fatigue, poor memory, and significant changes in emotions.
[How to reduce the damage to the skin caused by makeup]
1. Pre-makeup skincare
The skincare methods for dry skin, oily skin, and combination skin are different. Choose the appropriate skincare method based on your specific skin condition. The main steps are cleansing + toner + eye cream + essence + cream, and then apply a primer.
2. Choosing cosmetics
Some ingredients in makeup can easily cause skin problems. In addition to checking the instructions, try the product before purchasing or choose products based on your skin type. Oily skin should avoid choosing greasy and heavy makeup, as excessive sebum production can easily cause enlarged pores, and the oils in makeup products can absorb dust from the air, further blocking the pores and causing the growth of pimples.
3. Take breaks from makeup
Let the skin rest. Accumulating makeup without breaks can harm the skin. Therefore, give your skin proper rest, such as not wearing makeup when staying indoors, and only do basic skincare for the skin.
4. Proper cleansing
Makeup itself does not harm the skin. The real reason for skin damage is not properly cleansing. Choosing a suitable makeup remover is essential.
5. Avoid heavy makeup
It is advisable to wear light makeup in daily life. Heavy makeup not only looks unnatural but also inhibits the skin's "breathing". How to test cosmetics for sensitive skin
