Cultivate thick skin, my ultimate goal of skin care!
The word "cheeky" here is not a derogatory term. From the perspective of skin care, thick skin is more healthy!
It refers to our skin skin The barrier is healthier, stronger, more tolerant, and the skin is more stable 。 On the contrary, the face is biased Thin skin is usually more prone to skin problems such as sensitivity, redness and spots. Especially when the season changes and the temperature difference becomes larger, the skin is particularly unstable.
As the largest organ of the human body, the structure of the skin is roughly divided into For the epidermis, dermis and subcutaneous tissue, each layer plays an important role in maintaining skin health.
The thickness of skin varies with different parts. The thinnest part is the eye skin, which is about 0.5mm thick. The average thickness of facial skin is about 1-1.5mm. The average thickness of the epidermis is about 0.2mm, which is the outermost layer of the skin. It is responsible for regulating moisture and electrolytes, preventing dryness, providing protective barrier protection for the skin, and resisting the influence of external harmful factors or substances.
Whether the skin is thick or not is generally determined by the epidermis, Most epidermal cells are keratinocytes. They are formed in the bottom layer of the epidermis. The new keratinocytes slowly migrate to the top layer of the epidermis. Once they reach the surface of the skin, they gradually age and fall off, and are replaced by new cells in the lower layer, That is, skin keratinocytes A complete metabolic cycle of. Normal skin cuticle metabolism cycle is 28~56 days That is, the time required for a keratinocyte to produce, grow, mature, die and fall off.
Thick skin mainly depends on the stratum corneum, and the stratum corneum and sebum film constitute the skin's natural defense barrier, so whether you are a "wall skin" or sensitive skin depends on Their status.
Among them, the congenital factors affecting thick skin are mainly related to gender and age. The average thickness of boys' skin is 1 μ m more than girls'. In addition, boys' metabolism is strong, and the amount of oil secretion is too high. It is easy for aging cutin to accumulate and block pores. Of course, if girls meet Hormone disorders in the body (excessive pressure) will also cause the same skin problems; secondly Age will affect the rate of cutin renewal, and the loss of collagen will also lead to thinner skin.
In addition to the above congenital reasons, There are also many acquired factors that affect the health of the stratum corneum, For example, excessive cleaning, frequent exfoliation, acid brushing, and frequent use of some powerful skin care ingredients. In contrast to your skin care habits, if you have the above skin care habits and your skin is also in an unstable state, you should pay attention, You may not be thick skinned enough!
Do not over clean
People who wash their faces with soap based ingredients in the morning and evening should pay attention. Your sebum film may not be able to synthesize as fast as you scrub it!
Mild amino acid cleanser and oil are recommended for general sensitive skin Tian or Oilskin recommend soap base compound amino acid ingredients for cleansing, which will have a stronger degreasing power. If you get up in the morning and your face is not very oily, Clean with clean water, It is not necessary to clean the face, maintain the integrity and natural protective power of the sebum film, and do a good job of removing makeup and cleaning care at night to lay a good foundation for subsequent night maintenance.
Do not exfoliate or brush acid frequently
Many people want to improve their rough skin, acne, dark spots and other problems, so they choose exfoliation or acid brushing care. There is no wrong choice, But the problem is frequency.
Exfoliation or Acid brushing Will accelerate the exfoliation. If you peel off the old and waste cutin, it is the best result, and the skin will become more transparent and healthy.
But if there are obvious symptoms of damaged barriers such as redness, sensitivity and fever, it is necessary to consider whether the nursing is overdone? This is because the probability is that the newly born keratinocytes are pushed up by accelerated metabolism before they are mature. At this time, the keratinocytes are not only unstable, but also cause subsequent problems of skin metabolism disorder. The correct treatment is to judge the exfoliation frequency according to the product's temperature, Generally, 1-2 times/week for mild type and 1 time/month for high concentration. Give our keratinocytes some time to grow!
Repair the barrier=nourish the skin
Choose more barrier friendly ingredients and products with the function of repairing the barrier to protect the skin.
For dry skin, glycerin, urea, avocado resin, phospholipid and other ingredients can be selected. They have a good moisturizing effect of supplementing high-quality oil, absorbing water and locking water; The sensitive skin and oil mixed skin can choose to contain ceramide, hyaluronic acid, squalane and other ingredients to help thicken the stratum corneum, improve the water retention and tolerance of the skin, so as to achieve the function of strengthening the barrier; During the sensitive period, ingredients such as B5, bisabolol, and potassium glycyrrhizinate can also be used to relieve allergy and reduce skin discomfort.
In the era of more and more skin care products and sensitive skin, it is time to put aside the fancy propaganda and concepts and choose the products suitable for you from the most basic skin composition and needs!
Our skin has its own growth and repair frequency, so long as we do a good job in skin care, we can make healthy thick skin no longer a "rare product"!
