Because of its left-handed characteristics, it has good biological compatibility, can be compatible with mammals, can directly participate in human metabolism, without any side effects, and is widely used in food, medicine and other fields.

Difference Between L-Lactic Acid & D-Lactic Acid

Lactic acid is the smallest chiral molecule in nature, and the carboxyl group in the molecule α The position carbon atom is an asymmetric carbon atom with L (+) and D (-) configurations. L-lactic acid is left-handed type, D-lactic acid is right-handed type, L-lactic acid and D-lactic acid are mixed in equal proportion to form racemic DL-type. The physical and chemical properties of D-lactic acid and L-lactic acid are the same except for their optical activity, but the physical properties of DL-type are different from them, which is shown in that their melting point and heat of melting are lower than those of single D or L configuration.

D-lactic acid is dextral lactic acid, which cannot be absorbed by human body; L-lactic acid is L-lactic acid that can be absorbed by human body; DL-lactic acid is mixed rotational lactic acid. D-lactic acid and L-lactic acid are optical isomers of each other. DL-lactic acid is their mixture.

Types of Liquid Lactic Acid

01

L-Lactic Acid

Lactic acid is divided into L-type (79-33-4); Type D (10326-41-7); DL type (50-21-5), with an asymmetric carbon atom in the molecule and optical activity, has two optical isomers of L-lactic acid and D-lactic acid. There are fermentation and chemical synthesis methods to produce lactic acid in industry. At present, L-lactic acid is mainly produced by fermentation at home and abroad; The law of chemical synthesis generates racemic lactic acid, namely DL-lactic acid. Because there are only enzymes that metabolize L-lactic acid in the human body, if excessive D-lactic acid is ingested, it will cause metabolic disorder and even acidosis. Therefore, L-lactic acid is needed as raw material in the food industry, or in the manufacture of lactic acid esters and polylactic acid for medical applications.

Benefits of Liquid Lactic Acid For Skin

Liquid Lactic Acid helps called exfoliation. Lactic acid speeds up cell turnover and stimulates cell renewal.

Liquid Lactic Acid helps to dissolve the plug of skin cells that build up around the hair follicle, smoothing out the bumpiness.

Liquid Lactic Acid can help to fade sun spots or age spots and can smooth and soften fine lines and wrinkles.

It helps to improve the skin's natural moisture factor or the way the skin keeps itself hydrated.

How to Use Liquid Lactic Acid in Skin Care?

It can create real change in the skin if used regularly.

It's one of the more gentle hydroxy acids used in skin care. All alpha hydroxy acids exfoliate and improve skin texture, but lactic acid has an extra benefit you won't get from other AHAs, like glycolic acid and mandelic acid. When you use lactic acid regularly, it can also improve signs of aging. It does so by stimulating the renewal of collagen, a fiber that helps to keep the skin firm. Lactic acid is an alpha hydroxy acid that is used on the skin to remove dead skin cells and help fade dark spots and soften fine lines. Start off with a low-strength product, especially if you have sensitive skin. And be sure to also use sunscreen, as lactic acid makes your skin more prone to sunburn.
