Daily maintenance, but acne, acne, dry skin, sensitive muscles and other problems have not been solved, but continue to find you? In fact, the time difference between the wrong cleaning method and the weak acidic skin care products may be more than 3 hours, which is the period of skin recovery. Acid-base balance is the key to the health of facial muscles. Dermatologists point out that when the pH value is out of balance, it is easy to make the skin in a low protective state, especially after cleaning, the pH value will not recover immediately, but it will take 1 hour to restore the original balance. Doctors said that with more and more waterproof cosmetics and sunscreens, and easy to get oil in summer, many women often use products with too many ingredients without knowing it, which is more likely to cause pH imbalance. The doctor explained that when the sebum membrane is kept slightly acidic at pH4.5 to 6, it can balance the ecological environment of the skin and maintain a healthy skin state. When in alkaline environment, sebaceous glands will secrete more vigorously, which is easy to breed bacteria and cause inflammation such as acne and acne. Although the skin has an automatic recovery mechanism of pH value, according to research, it takes more than 3 hours for the skin to regain its balance when using alkaline cleaning products. In particular, most cleaning products on the market are alkaline, which can effectively remove sebum, but it is easier for the skin to lose moisture. After cleaning, because the sebum membrane is damaged and there is no barrier to protect it, the water is easy to evaporate. At this time, if we continue to use non-weakly acidic skin care products, it will not only delay the recovery time of normal pH value of the skin, but also greatly reduce the defense of the skin for a long time, which is more likely to cause problems such as sensitivity and dryness. This is one of the reasons why some women spend a lot of money on skin care products, but they can't achieve the expected results. Doctors suggest that cleansing and moisturizing products should be close to the pH value of the skin. Using weakly acidic products with pH5.5 can shorten the recovery time and form a weakly acidic protective film at the same time, so as to avoid the disorder of external * * * and sebum secretion and cause problem skin conditions.
