Hello dear ~ I am very happy to answer this question for you. The reasons why your face becomes drier after applying hydrating essence are as follows: 1. Oily skin does not require moisturizing because there is no absolute relationship between the amount of oil produced by the skin and the sufficient moisture content of the stratum corneum. People with oily skin are not necessarily dehydrated, so it is still necessary to adjust the moisturizing products used according to the skin condition. 2. Frequent exfoliation Although exfoliation can help the skin regain its luster, exfoliating too frequently (for example, more than once a week) or using several exfoliating products at the same time will make the cuticles become thinner and thinner. Thin, it loses its ability to store water and resist damage from the external environment. 3. Use summer facial cleanser in winter to say goodbye to the hot summer and your face will no longer be shiny. If you still use strong cleaning products to wash your face like in summer, your face will become drier and more likely to cause allergic symptoms such as redness, peeling, itching, etc. . 4. Frequently spray mineral spring spray during daily maintenance. Some people like to carry a bottle of mineral spring spray with them so that they can take it out and spray it at any time to relieve discomfort. In fact, this may dry out the skin's original moisture. 5. Frequently apply moisturizing masks. Masks are mostly used for first aid. If used too frequently, the skin will become dull and lose its protective ability. The skin cannot bear such a burden, so apply moisturizing masks appropriately. Do not apply it every day, but apply it once a week. 2-3 times is enough. 6. Never end the skin care process by just applying lotion without using facial cream, because the added moisture will not be firmly locked in and the skin will still not be cared for and repaired. 7. Excessive drinking of water. Normal and healthy skin only needs to ensure that the water content reaches 30%, so if you have this idea, don’t make the same mistake again. Drink water in moderation. Eight glasses of water a day is enough.
