Recommendations and suggestions for Vital Skin - Strengthening Hyaluronic Acid Super Serum:
Ingredients
Q: What are the main ingredients of this serum? What are their functions?
A: The main ingredient is hyaluronic acid. Hyaluronic acid molecules come in different sizes, and this serum may contain hyaluronic acid of different molecular weights. Large molecule hyaluronic acid can form a moisturizing film on the surface of the skin, effectively locking in moisture, preventing skin moisture loss, and keeping the skin hydrated. Small molecule hyaluronic acid can penetrate deep into the skin, replenish moisture to skin cells, plump up the skin from the inside, and enhance skin elasticity. In addition, it may also contain some plant extracts, vitamins and other ingredients. Plant extracts help soothe the skin, resist oxidation, and resist free radical damage to the skin; vitamin ingredients (such as vitamin C, E, etc.) can promote collagen synthesis, brighten the skin, reduce wrinkles, and further strengthen the health of the skin.
Efficacy
Q: What are its main functions?
A: The main functions are moisturizing, hydrating and skin strengthening. Through the action of hyaluronic acid, it can provide deep moisturizing for the skin, improve the dryness and dehydration of the skin, and make the skin soft and smooth. Long-term use can enhance the barrier function of the skin, improve the self-repair ability of the skin, and make the skin healthier and more elastic. And it may also have a certain auxiliary effect on brightening the skin tone and reducing fine lines, which helps the skin to appear young and energetic.
Usage related
Q: What is the correct method of use?
A: After cleaning the face and using toner, take 3-4 drops of essence and apply it evenly to the entire face, gently massage, start from the chin in a circular manner, apply upward to the forehead, and then apply to the cheeks from the inside to the outside to help the essence be better absorbed by the skin. It can be applied to dry, dehydrated or fine-lined areas. It is recommended to use it once in the morning and evening. After using the essence, you can continue with normal moisturizing skin care steps, such as applying lotion or cream.
Applicable skin type related
Q: What skin type is this essence suitable for?
A: It is suitable for all skin types. For dry skin, it can provide deep moisturizing and relieve the problem of dry skin and dehydration; for oily skin, its texture is usually light, which will not add greasy burden to the skin, and can help regulate the water and oil balance of the skin; for neutral skin, it can maintain the good condition of the skin; for sensitive skin, because its main ingredient hyaluronic acid is relatively mild and may contain soothing ingredients, but users with sensitive skin are recommended to try it on a small area of skin for the first time to observe whether there is an allergic reaction.
Product comparison related
Q: Compared with other hyaluronic acid essences, what are its characteristics?
A: Its characteristics are that it not only has moisturizing effects, but also emphasizes skin strengthening. Compared with some simple hyaluronic acid essences, it may improve skin health from multiple angles by adding other active ingredients, such as plant extracts and vitamins. Its formula may focus more on improving the skin's barrier function and enhancing its self-repair ability. While moisturizing, it provides more comprehensive care for the skin, making the skin tougher and more energetic.
Storage and other related
Q: How should this essence be stored?
A: Store in a cool, dry place away from direct sunlight and high temperatures. After each use, make sure the lid is tightly closed to prevent air from entering and causing oxidation or bacterial growth. If the texture, color or smell of the product changes significantly, stop using it.
Q: Can pregnant women use this essence?
A: Because pregnant women have more sensitive skin and are in a special physiological period, they need to be cautious about the ingredients in the essence. Generally speaking, hyaluronic acid is relatively safe, but if it contains other ingredients that may pose a potential risk to the fetus (such as certain plant extracts or active ingredients), it is recommended to consult a doctor before use.
