Drop a few drops of hyaluronic acid stock solution and gently massage from the center of the face to both sides until it is absorbed. Make-up water can provide sufficient hydration foundation for hyaluronic acid, so as not to let hyaluronic acid absorb back the original moisture of the skin.
Note: dilute the uric acid solution in the emulsion. The commonly used hyaluronic acid concentration is 0.025~0.05%. If the concentration is high, it will not only be sticky, but also feel bad when applied, and there will be the phenomenon of skin dehydration mentioned before.
Lock water and moisturize (the last key step): don't forget to prevent hyaluronic acid from drying quickly! We need to add a "sealing agent" to the skin when hyaluronic acid has been absorbed but not completely dried. The so-called "sealing agent" is simply something that can form a closed form on the skin surface. It is more effective to apply moisturizing cream or gel to lock in moisture.
Extended data:
Hyaluronic acid can help the skin absorb a lot of water. With water, the skin will naturally remain elastic and soft.
Hyaluronic acid will gradually form a film rich in water in the stratum corneum, and transport water inward and outward at the same time. Therefore, when the environment is dry, it is necessary to rely on the sealing agent to reduce its outward water evaporation in order to maintain water for a long time. Sealants can form a thin film on the skin surface to prevent water from "losing". Sealants are usually greasy, such as vaseline, mineral oil and silicone derivatives.
The emollient fills the gaps between the outermost cells of the epidermis, making the skin surface texture smooth and soft, and reflecting the efficacy and beauty effect of cosmetics in a short time. According to different internal characteristics, it can be divided into protective, degreasing, drying or convergence. In addition to moisturizing, hyaluronic acid has a little moisturizing function.
