First, find out the sensitivity and allergy
[Sensitivity] Mainly refers to the skin’s immediate discomfort with the environment or substances it comes into contact with, such as pricking, itching, heat and pain. Usually sensitive symptoms are limited to the contact area, and these discomfort can be eliminated after the sensitive substances are removed.
[Allergy] is the mechanism of human body’s self-protection. When foreign bodies invade into the human body, our immune system will start to attack these foreign bodies, thus producing allergic symptoms such as redness, swelling, heat or pain.
Allergy is more serious than sensitivity and can spread. For example, hair dye allergy can spread from scalp to face or neck. Severe cases can also cause other side effects or life risks. Therefore, when allergy occurs, seek medical treatment immediately and provide the products causing allergy to doctors for diagnostic reference.
Second, what is the relationship between sensitivity and skin barrier damage?
A healthy skin barrier, like the outer wall of a building, must have a complete structure.
Our skin barrier includes sebum membrane and stratum corneum. Complete sebum membrane coverage and sound stratum corneum are the best guardians of skin.
However, there are many behaviors in daily life that will lead to the decline or destruction of skin barrier function, such as excessive cleaning, strong cleaning, improper exfoliation, excessive use of cosmetics or weather effects, etc. These conditions will lead to foreign bodies invading the skin more easily, thus making the skin more sensitive.
Three, daily care sensitive muscles, gradually repair the skin barrier
First, the principle of skin care for sensitive muscles.
Gently clean, strengthen moisturizing, do not exfoliate, pay attention to sun protection, do not blindly pursue whitening, freckle removal and other effects, when necessary, please stop using any products for a period of time, so that the skin has a chance to rest.
When the skin is abnormal or untimely, it is not necessary to find cosmetics to use as soon as possible, but to clean and remove the substances on the skin with clear water first, then take a rest and do not wipe anything. If there are special circumstances, you must also seek help from a dermatologist for diagnosis and treatment.
Second, sensitive muscle cleaning steps and precautions.
For sensitive skin, Do not choose soap cleaning products, All saponified products, including handmade soaps, are fatty acid + alkali, The amphoteric molecular structure in soap, Strong electrostatic adsorption, In addition to its strong ability to remove fat, It can also lead to stratum corneum stripping, which will be damaged and disturbed in the long run. It is recommended that you use milder amino acid cleansing products, glucoside surfactant products or some natural surfactant ingredients (e.g. Sodium lauryl glucose carboxylate (and) lauryl glucoside (and) lauryl glucoside). These are quite mild ingredients.
However, if the sensitive problem is quite serious or often sensitive, it is recommended not to use any cleaning products and only wash your face with clear water.
It is recommended to choose warm water that is a little higher than the body temperature (about 40 ℃). If the temperature is too high, It will increase the effect of removing lipid, and the skin will feel dry and uncomfortable after washing. At the same time, the shorter the cleaning time is, the better. Try to finish the cleaning within 1-2 minutes. After washing, gently press the towel dry to avoid rubbing, because this will make the fibers on the towel rub the skin and cause skin injury.
4. Selection of ingredients for skin repair and skin care products
The simpler the skin care products recommended for sensitive skin, the better, the milder the ingredients, and the less the ingredients, the better.
It is suggested to choose skin care products without perfume, pigment and simple ingredients. The more ingredients, the higher the probability of allergy.
It is recommended to use cream or emulsion with grease components. When using emulsion or cream, the amount of application must be sufficient. It is recommended that you can apply it many times. When you feel as if you have applied it a little too much, it is the right amount.
Also don’t apply facial mask, because applying facial mask is not helpful to sensitive skin at all, and it is more likely that the skin must be forced to absorb a large amount of water, resulting in excessive skin hydration, reduced barrier function, and more likely to cause skin discomfort.
In recent years, some related studies have shown that when skin needs repair, it is recommended to choose products containing the following ingredients:
- Physiological lipid products can accelerate skin recovery: ceramide, cholesterol and free fatty acid are matched with specific molecular weight concentration; Moisturizing ingredients can strengthen skin moisturizing: glycerin, sorbitol, urea or hyaluronic acid, etc. Ingredients to help skin repair: allantoin, plant polysaccharide, panthenol D-panthenol, vitamin B5, vitamin B6 and vitamin E, etc. Ingredients for preventing skin sensitivity and discomfort: dipotassium glycyrrhizinate, myrrh alcohol, plant polysaccharide, Beta glucan, aloe extract or cactus extract, etc.
