For example, most skin-changing products contain stimulating fruit acids, which are extracted from various fruits, including grape acid, malic acid, citrus acid and lactic acid. Because most of them are extracted from fruits, they are commonly called fruit acids. A certain concentration of fruit acid can promote the exfoliation of stratum corneum through acid erosion, achieve metabolism and change the skin, but it is a kind of stimulation to the skin. When the concentration is too high, users can still feel obvious tingling, which will lead to redness, allergy and inflammation.
Before buying, consumers can apply the trial package behind their ears for skin test. After 12 hours of observation, they can use it safely without allergic symptoms. At the same time, pay attention to diet, sleep and daily skin care to avoid sun exposure and contact with allergens. In addition, consumers with sensitive skin should avoid using pharmaceutical cosmetics as much as possible, which may cause problems such as pigment accumulation.
Special care of sensitive skin
The care of allergic skin needs extra care. After cleansing in the morning, in addition to moisturizing, you should also use a special day cream for sensitive skin and apply sunscreen before going out. After washing your face in the evening, apply a hot towel to your face for 2 minutes, then apply a cold towel to your face for 65,438+0 minutes, then apply a nourishing lotion to your face, pat it gently to let your skin absorb it, and finally apply a moisturizing and anti-allergic night cream and gently massage it until it is absorbed. Special attention should be paid to:
1. Sensitive skin should not be exfoliated. Do not use soap lotion. For products such as scrub and exfoliating cream, stay away.
Sensitive skin should be protected every day. Because the epidermis of sensitive skin is thin and lacks the ability to defend against ultraviolet rays, we should pay attention to the use of sunscreen products. The ingredients of sunscreen products are also one of the factors that easily irritate the skin. Therefore, it is best not to apply sunscreen products directly, but to apply sunscreen products after basic care.
3. Moisturize sensitive skin. The shallow stratum corneum of sensitive skin often can't keep enough moisture, and it is easier to feel dehydrated and dry than ordinary people, so it is very important to strengthen moisturizing in daily maintenance.
4. Sensitive skin should not be over-nourished. This is because modern cosmetics emphasize high efficiency. For sensitive skin, high concentration and good effect means high risk and high sensitivity. Therefore, when people with this skin type use skin care products (especially high-concentration activators such as essence), it is more appropriate to dilute them by half before using them. In addition, sensitive skin is not suitable for products with strong curative effect, and the best way to restore skin health is to use non-curative products that do not increase the burden on the skin.
5. Try not to wear heavy makeup. If skin allergy occurs, stop using any cosmetics immediately and observe and maintain the skin.
