In autumn and winter in the north, the cold wind is bleak and the sky is dry. In autumn and winter in the south, the moisture returns and the sunshine is hard to see. Although it is cold, one is dry and the other is wet and cold. The skin obviously changes its state in spring and summer. Sensitivity, flushing, dryness, peeling… all come.
At this time, many moisturizing creams are not as effective as before, and their moisturizing power decreases.
The skin turned red, sensitive and rough, and there was even a faint tingling sensation on the face… I couldn’t bear to touch my face.
If you want good skin in autumn and winter, moisturizing is indispensable.
If you want to maintain your skin well, you must start with protecting the skin barrier. The simplest way is to apply humectant.
Moisturizing agent, as its name implies, can form a protective film on the skin surface to prevent moisture loss.
Some ingredients of some moisturizers also have the function of repairing skin barriers. These ingredients are called natural moisturizing factor (NMF). As the name implies, NMF is a moisturizing factor that can be synthesized by human skin itself. Common ones are:
- Ceramide: It can play an anti-inflammatory, anti-cell division and antipruritic role; Sodium pyrrolidone hydroxylate: strong water solubility and permeability, no sticky feeling of glycerin, and better moisture retention than glycerin; Lactic acid: It has the function of repairing skin barrier and can combine water in epidermal cell space. Urea: Cheap and easy to use, it is the king of cost performance for [dry housewives’ hands].
How should skin moisturizer be selected?
The selection of what moisturizer is related to the living environment and the needs of the skin itself:
No matter north or south, hyaluronic acid-containing essence can be used to lock water and moisturize. It can absorb 500 times of its own volume of water and form a moisturizing film on the skin surface. However, remember to use more moisturizing water before using, otherwise hyaluronic acid essence may [rub mud] instead.
- Students in the north had better choose skin care products that contain more closed types, because the sky is dry and the wind is strong, and it is very important to close moisture. Students in the south can choose skin care products with the main ingredients of moisturizing type and the secondary ingredients of moisturizing type.
What do what mean by closed type, moisturizing type and moisturizing type?
Draelos, an American dermatologist, pointed out that humectants can be roughly divided into four types according to their ingredients: closed type, moisturizing type, moisturizing type and therapeutic type.
1. Closed humectant
It has good moisture absorption capacity, can keep moisture for a long time and seal moisture.
2. Moisturizing agent
It can prevent water evaporation, make skin stratum corneum cells flexible and soften, and make water from deep epidermis and dermal tissues enter stratum corneum.
3. Moisturizing type moisturizing agent
It can prevent water from evaporating.
4. Therapeutic moisturizer
Balance combines the ingredients of the above three types to ensure smooth skin and better moisturizing effect.
Acne, red blood streak, sensitive problems, how to do?
Acne, red blood streak, sensitivity… These mean that the skin is no longer in [normal state] and cannot be completely solved by skin care products alone. They are not drugs, only auxiliary functions, and have no [curative effect].
To solve the problem, the idea should be to first clarify the problem [is what], is [how to come from], how to [standardize treatment], and then talk about how to use skin care products to assist in improving the effect.
Acne
For acne, salicylic acid and tartaric acid are added to some skin care products. They can help stratum corneum metabolism, inhibit epidermal flora, reduce acne and have certain anti-inflammatory effects. However, they are not suitable for all acne muscles, which may lead to thinner skin for certain people with extremely thin epidermis.
Red blood streak
For red blood streak, some people are prone to flushing due to congenital vascular development, while others are due to vasodilation caused by hormone, sun exposure, drugs, diseases and other factors. Red blood streak is difficult to improve through skin care products, focusing on [prevention] rather than [treatment], such as good sun protection to prevent ultraviolet rays from stimulating vasodilation.
Skin sensitivity
For sensitive issues, whether it is [skin sensitivity] or [skin allergy], if the two are confused, it is not certain whether skin care products can be improved or not. If it is not possible, it will delay the illness. Don’t be lazy. The doctor will help you see it, or ask [Dr. Clove] and then choose the appropriate skin care products.
