7, moisturizing and hydrating methods
1, pure water moisturizing method
The drier the climate, the more water the skin evaporates, and the easier it is to dry and lack water. Once the skin is chapped, it means that your skin is very thirsty, so you must moisturize and replenish water for your skin in time. Girls can moisturize their skin with pure water. When we drink water, we can wet our hands and pat them on the facial skin, so that we don't need too detailed moisturizing care, and actually have added a lot of water to the skin. Girls can pat our skin whenever and wherever they drink water, so that our skin is not short of water.
2, fruit and vegetable hydration method
Fruits and vegetables can not only be eaten to supplement nutrition for the body, but also be the most nutritious and healthy choice for hydrating and moisturizing the skin. Girls can usually eat more fruits and vegetables, such as cucumbers, apples, grapes, cherries and so on. These fruits and vegetables can fully replenish enough water for the skin, act on the skin, make the skin more elastic, and make the dry skin more moist. Girls can also juice fruits and vegetables and drink them to make a moisturizing and hydrating mask, which directly acts on the skin surface, and the moisturizing and hydrating effect is still leverage!
3, vitamin cream moisturizing method
Girls always use skin care products and toner to replenish water and moisturize. Only when skin care products are selected correctly can they have a good moisturizing effect. Bian Xiao suggested that girls try to choose creams containing vitamins, especially those containing vitamin C and vitamin E, which will make the skin whiter, more moist and more shiny.
