Hyaluronic Acid (HA) is a sugar molecule with the scientific name Polysaccharide. HA has a molecular weight ranging from 600,000 to 1,000,000 Dalton units. Thanks to this special structure, HA has superior water retention ability, as 1 gram of HA can hold 6 liters of water.
It is because of this superior water retention property that in the early years of the 80s, it was applied in the cosmetics industry.
HA Serum (Hyaluronic Acid) is highly appreciated for its moisturizing capability and optimal lipid barrier reinforcement.
This is a skincare serum with Hyaluronic Acid (HA) as the main ingredient, which helps maintain moisture and firmness on the skin surface. It has the function of nourishing the skin and effectively treating acne scars and pitted scars.
Specifically, Hyaluronic Acid is a naturally occurring substance in the human body. It acts as a moisture magnet, making the skin feel “hydrated,” plump, and healthy. However, over time, due to the effects of aging, the concentration and weight of HA decrease significantly.
Mistakes when applying HA
– Hyaluronic Acid is very prone to reverse evaporation. Many people tend to apply only a layer of HA serum on the skin and do not apply any other moisturizers or lotions to lock in moisture. Or after applying HA, many people still wait for 5 – 10 minutes for the serum to be absorbed before applying the moisturizer. These two habits will cause HA to evaporate significantly, drawing moisture out and no longer effectively working on the skin.
– Improper combination of HA with other ingredients. Hyaluronic Acid is very gentle on the skin, but it is very selective in combining with other active ingredients such as artificial fragrance (parfum), scented essential oils, alcohol, etc.
Should HA be used daily?
Unlike some acids, HA does not damage or cause strong irritations on the skin. Basically, Hyaluronic Acid is a natural and powerful moisture-binding substance that gently provides moisture, improving dull skin.
When should HA serum be used?
– Use a serum with HA extract when you are concerned about aging: This is when wrinkles and dryness will increasingly appear. Therefore, if you want to maintain a youthful appearance, incorporating hyaluronic acid into your skincare routine to fight aging is definitely a great idea.
– Use HA serum when the skin is not well moisturized: Unlike dry skin, dehydrated skin can have more wrinkles and tend to look dull. It also often feels rough, tight, and makes the foundation of the skin become sensitive.
How to care for the skin with HA serum?
Hyaluronic acid (HA) is a versatile moisturizing substance, and it is completely harmless, not interfering with the effects of other skincare products. Therefore, you can directly apply the HA serum on moisturized skin for its full moisturizing ability to take effect. If your skin is dry, apply a moisturizer first (to help the skin have an additional moisturizing foundation).
