Hyaluronic acid is a natural substance found in the fluids in the eyes and joints, and it is used in cosmetics in skin care and make-up products for its moisturizing and anti-aging benefits. It can help increase the moisture content in the skin, which can have various skin benefits, including reducing the appearance of wrinkles and improving wound healing, among others. Hyaluronic acid is produced by biotechnology, obtained by bio-fermentation, and collected, purified, and dehydrated to form a powder. The hyaluronic acid used in cosmetics is of natural origin, has a good environmental profile, and is biodegradable.
Here are some positive and negative aspects of hyaluronic acid products:
Positive:
- Hydrates the skin and slows down the rate at which water evaporates.
- Improves the suppleness and softness of the skin.
- Can improve wound healing.
Negative:
- Some hyaluronic acid products can dry out the skin.
- Some hyaluronic acid products contain ingredients that are generally toxic or harmful, such as parabens, certain preservatives, PEGs, and silicones.
It is important to note that the benefits of hyaluronic acid on the skin have to do with its molecular weight and concentration. The size of the hyaluronic acid fragments is selected so that they only penetrate the uppermost layers of the skin. When choosing a hyaluronic acid product, it is important to consider the ingredients or materials used and to look for products that are of natural origin and have a good environmental profile.
