Hyaluronic acid stock solution is the best ingredient to moisturize and lock water, and the effect is extremely remarkable. However, with the increase of age, hyaluronic acid in the skin is also decreasing. Applying this stock solution can help the skin to enhance elasticity, keep it moist and rejuvenate.
Hyaluronic acid in the skin began to lose at the age of 25, leaving only 65% in infancy at the age of 30 and only 25% at the age of 60. The moisture of the skin will also lose its elasticity and luster with the loss of hyaluronic acid, and wrinkles will appear after a long time.
When choosing hyaluronic acid stock solution products, we must pay attention to choosing products without preservatives, because many substances in preservatives have a great stimulating effect on facial skin, which will lead to skin allergies.

Matters needing attention in using hyaluronic acid stock solution:
1. In fact, the hyaluronic acid stock solution on the market is mostly hyaluronic acid products with a concentration of 5%, but even the concentration of 5% cannot be directly applied to the skin, because it not only fails to achieve the moisturizing effect, but also may absorb too much water from the dermis, making the skin drier.
2. Pay attention to using high-concentration hyaluronic acid stock solution alone when the skin is dry, otherwise it will not only have no moisturizing effect, but also absorb the moisture of the skin, because its water absorption is very strong, which is counterproductive. ?
3. Pay attention to cleanliness when using hyaluronic acid stock solution, and use it only once. The packaging of hyaluronic acid stock solution is damaged and cannot be used.
4. After using the hyaluronic acid stock solution, if the skin has an inflammatory reaction and the pressing is accompanied by pain, you should stop using it in time and consult a doctor immediately if necessary.
