How to use hyaluronic acid serum?

What is hyaluronic acid?

Hyaluronic acid is an acidic mucopolysaccharide, which was first isolated from the vitreous body of the bovine eye. Most importantly, it has a special water-retaining effect, and it is the substance with the best moisturizing property found in nature, which is called an ideal natural moisturizing factor.

Hyaluronic acid serum properties

Hyaluronic acid (hyaluronic acid) exists in a large amount in the connective tissue and dermis of the human body. It is a transparent jelly-like substance that is filled with water and can be said to be a moisturizing factor for the skin. 1 gram of hyaluronic acid can absorb 500c.c. of water, which is equivalent to 500 times the water absorption capacity. The powerful moisturizing function makes hyaluronic acid a popular moisturizing ingredient. Compared to collagen molecules, which can only carry thirty times more water, hyaluronic acid molecules can carry more than five hundred times more water, and are recognized as the best moisturizing product in the literature today.

Progenitor hyaluronic acid exists in the skin, and proper supplementation of hyaluronic acid can not only help the skin absorb a large amount of water from the body and the skin surface, but also enhance the skin's long-term water retention capacity. When hyaluronic acid absorbs a lot of water, the elastic fibers and collagen are in a water-filled environment, and the skin is more elastic. Young skin is rich in hyaluronic acid, so it is soft and elastic. After the age of 25, the hyaluronic acid begins to lose. At the age of 30, only 65% ??of the childhood is left, and at the age of 60, only 25% is left. Hyaluronic acid will be lost with age, causing the skin to lose moisture, lose its elasticity and luster, and cause wrinkles and aging in the skin for a long time.

Pure hyaluronic serum skin care benefits

As early as the early 1980s, the excellent moisturizing function of hyaluronic acid received extensive attention from the international cosmetic industry. Hyaluronic acid can absorb a lot of water when applied to the skin. No matter it is used in various humidity, climate, environment and different skin types, it has the same high water retention, and its actual effect has exceeded the hydration degree of the stratum corneum, so for extremely dry or aging to severely dehydrated skin, hyaluronic acid is the ideal moisturizing ingredient. 

The normal water content of the stratum corneum is between 10 and 15%. If the water content is less than 10%, the skin will begin to dry and desquamate, which will further cause the water loss of the dermal tissue, resulting in the formation of wrinkles and sagging. Hyaluronic acid can increase the moisture content of the skin, maintain the moisture of the skin, make the skin appear elastic and shiny, achieve long-term moisturizing, and retain the skin's moisture.

1. Moisturizing properties, help skin hydrate and maintain elasticity

Hyaluronic acid is produced by cells in the dermis, where it locks in moisture to maintain skin hydration. When applied topically, the same water-locking effect can be used to keep the stratum corneum (the surface of the skin) supple and plasticized. Half of the body's hyaluronic acid is found in the skin, which hydrates and locks in moisture and maintains barrier function.

2. Antioxidant properties help slow signs of aging and prevent free radical damage

Hyaluronic acid has been shown to be a particularly potent antioxidant that protects skin lipids (free fatty acids, etc.). Hyaluronic acid also boosts the activity of other skin antioxidants.

3. Help accelerate wound healing and maintain a moist environment between cells

Cell division is accelerated in this condition, promoting the formation of healthy connective tissue. Therefore, the use of hyaluronic acid before and after cosmetic procedures such as laser and fruit acid can effectively accelerate postoperative healing and reduce subsequent adverse reactions to the skin.

4. Anti-glycation properties

Hyaluronic acid protects against the damaging effects of sugar, "glycation" which is a major cause of human aging, including the formation of wrinkles and thinning of the skin. Supplementing hyaluronic acid may be particularly helpful for diabetic patients, and for the dry and aging skin that diabetic patients are prone to, external use of it and squalene-containing oils can help improve skin function and prevent dry skin and ulceration.

Can ha hyaluronic acid be used directly?

Due to the high price, the general hyaluronic acid stock solution provides a higher concentration of hyaluronic acid, which requires consumers to use it with a lotion. When the skin is dry, if you use a high concentration of moisturizing agent (such as 5% hyaluronic acid) alone, there is no direct moisturizing effect, and even because the hyaluronic acid absorbs a lot of water from the skin, it will make the skin more dry after use.

Hyaluronan side effects

In contrast to its water absorption, its water retention is not ordinary. When you are in a dry background, the nutrients in the hyaluronic acid will evaporate quickly, revealing the phenomenon of sucking back the nutrients of the cells. Especially those high-purity hyaluronic acid will be more likely to cause dehydration of the skin. The hyaluronic acid stock solution must be used after intensive cleansing of the face, that is to say, carefully clean the face with facial cleanser and dry the water before using it.

Proper use of hyaluronic acid

Due to the high price, the general hyaluronic acid stock solution provides a higher concentration of hyaluronic acid, which requires consumers to use it with a lotion. When the skin is dry, if you use a high concentration of moisturizing agent (such as 5% hyaluronic acid) alone, there is no direct moisturizing effect, and even because the hyaluronic acid absorbs a lot of water from the skin, it will make the skin more dry after use. So the correct usage is, after washing your face in the morning and evening, you only need to put 2-3 drops of hyaluronic acid in the palm of your hand, mix with an appropriate amount of water, and apply it on the face thinly, which is more effective. A bottle of hyaluronic acid can also use 1- more than 2 months.
