We know that if the face is dry, we need to hydrate and control the oil on the face, but how to solve this situation of sweat and oiliness?A search on the Internet, almost all of them can see the words of water and oil balance, because the skin lacks water, so it produces more oil, so it is necessary to do a good job of hydration, maintain the skin state of water and oil balance, today the aromatic family will tell you where the water and oil in the water and oil balance come from.
*Where does the water come from?
Let's first understand the structure of **, the ** structure on our face is mainly composed of three levels: epidermis, dermis and subcutaneous tissue, and the water content of different levels is also different.
The water content of the dermis is usually between 70-80%, and the water content of the epidermis is usually between 10-20%, and its water basically comes from the dermis. The moisture provided by the dermis is mainly achieved through the ** and nutrients of the subcutaneous blood vessels. Since the epidermis is our outermost layer and is susceptible to environmental influences and loss of moisture, when we feel dry face, it is usually caused by a lack of moisture in the epidermis. If you want to be moisturized and not tight, you must do a good job of hydrating and moisturizing.
*Where does the fat come from?
The oil is mainly secreted by the sebaceous glands, which is a special cell in the ** that can secrete cellular substances to keep the ** lubricated and slow down the loss of water.
After understanding the **water and oil**, we can know that the degree of hydration is related to hydration and moisturizing, and the oil secretion is related to the sebaceous glands. Fundamentally, the water content and oil production of ** have their own causes and solutions, which belong to two different systems, so the water and oil balance is actually a pseudo-concept.
Why does skin get too oily or too dry?
Over-oiled. **The main cause of oil production is excessive production of sebaceous glands, which may also be related to genes, hormone levels and external environmental factors. For example, when the temperature rises in summer and ** is exposed to a sultry environment, the secretion of sebaceous glands will accelerate, resulting in increased oil production. When the use of harsh skincare products has caused a compromise of the barrier. It can also lead to an exacerbation of the problem of oiliness.
Too dry. The cause of dry skin can be the improper use of skin care products, frequent cleansing, etc. For example, dry skin should use refreshing skin care products, and oily skin should use moisturizing skin care products, and the wrong skin care method will cause the skin to be too oily and dehydrated. Frequent face washing or exfoliation will damage the barrier function, which in turn will affect the skin's ability to lock in moisture, and will also lead to skin hydration and dryness.
To sum up, whether it is too oily or too dry, it is inseparable from the damage of the barrier function!Therefore, building a healthy and strong ** barrier can reduce the appearance of over-oily or over-dry skin.
I hope that you can carefully understand your skin needs and choose the right skin care products to help your skin build a strong barrier and make your skin more beautiful.
