Alpha-lipoic acid (ALA) is an organosulfuric, vitamin-like compound that has antioxidant properties. It is also called thioctic acid and it can eliminate inflammation.ALA is formed naturally in the body and is also present in foods (red meat, by-products, green vegetables, potatoes, yeast).
Alpha-lipoic acid is considered a friend of diabetics, alcoholics and weight loss sufferers. It is also widely used in cosmetology. Our experts have talked extensively with pharmacologists and cosmetologists, so we are ready to provide comprehensive information on the useful properties of this antioxidant, its effects on the skin and give examples of successful use of thioctic acid in cosmetics.
Useful properties
Cosmetologists have identified a number of useful properties of thioctic acid:
Dissolves equally well in fat and water. ALA can easily bind to and work together with water-soluble (vitamin C) or fat-soluble (vitamin E) substances.
The skin’s protective barrier is not a barrier. It reaches its destination very quickly due to the small size of its molecules. The substance acts immediately.
Increases the effectiveness of vitamins C and E. This acid has an antioxidant effect not only on the outside, but also on the inside of the cells. It protects these micronutrients from free radicals. Combining these ingredients in a single formula is a very good solution.
It calms inflammation and regenerates. ALA is well tolerated by the skin, including sensitive skin. Products based on it are used for the treatment of all sorts of skin rashes. It is also appropriate to use this acid to combat hyperpigmentation.
Thioctic acid in its effect on internal organs is very similar to that of the B vitamins.
Cosmetic effects on the skin
Research into how alpha lipoic acid affects the skin continues to this day. But no one disputes that ALA can:
as a powerful antioxidant, to protect the skin, preserving the integrity of cells;
Stop glycation (deposition of sugar in collagen and elastin fibers);
to protect the collagen framework from damage;
Restore injured collagen;
Has a rejuvenating effect;
Smooth the skin;
Reduce pigment spots, wrinkles, inflammation.
A 2015 study proved that topical use of 5% ALA can visibly reduce the number of expression lines around the eyes and above the upper lip. Also an interesting study was conducted in 2017. It has proven the potential of ALA to reduce skin damage caused by exposure to tobacco smoke.
Use in cosmetic products
Alpha-lipoic acid is added to skin care products such as
Serums and “anti-age” creams;
wrinkle products for the skin around the eyes;
creams with sun protection properties;
Lotions for skin regeneration after tanning;
Acne and post-acne treatments.
Thioctic acid beauty products are mild, so they’re suitable for everyday use and for the skin around the eyes. These products can be used during periods of active sunlight. Because of its ability to regulate sebaceous glands, these products are suitable for problematic and oily skin.
