Azelaic Acid Benefits For The Skin

Essentially, azelaic acid has anti-inflammatory and antibacterial properties. This makes it effective in clearing pores of acne-causing bacteria and also fighting other problems such as rosacea or sensitive skin. The following are the main properties of azelaic acid.

Anti-inflammatory

Azelaic acid has the property of eliminating free radicals and slowing down or reducing inflammatory cascades; the latter are processes that occur every day in cells. As a result, this compound reduces inflammation of the skin and reduces the effects caused by exposure to the sun.

Antibacterial

Another of the most important properties of this substance is its bactericidal effect. Prevents the proliferation of microorganisms that cause skin infections such as comedones or acne. It is broad spectrum; that is, it attacks different types of bacteria and, unlike antibiotics, it does not cause resistance in these germs.

Keratolytic

In the superficial layer of the skin, or epidermis, there is keratin and this is made up of cells called keratinocytes. When they build up, they form corns and can lead to warts or corns. Azelaic acid helps to thin those areas with a lot of keratin, which, in turn, reduces clogged pores.

Depigmenting

The pigment that gives the skin its color is called melanin, and due to the action of an enzyme called tyrosinase, it can cause blemishes. Azelaic acid inhibits the action of this enzyme. In addition, unlike other products, it has a selective action, that is, it only works on hyperpigmented areas and not on normal ones.

Antiseborrheic

This is one of the most valued properties of azelaic acid. Its action reduces the natural production of sebum, which prevents the accumulation of oil in the pores and prevents or corrects the appearance of acne. The best thing is that it does not cause problems for people with sensitive skin.

Uses of azelaic acid

Azelaic acid is mainly used to treat active breakouts and / or scars  caused by this problem. It helps fight bacteria, reduces the keratinization present in blackheads or comedones and reduces the spots that remain as a consequence of acne.

This compound is indicated for mild or moderate acne cases. In any case, it would not be advisable for severe cases. This acid is also often incorporated as part of the treatment of other conditions:

• Rosacea. It can reduce inflammation and visibility of blood vessels.
• Hyperpigmentation of the skin. Any inflammatory lesion on the skin leaves a more or less visible spot, dark in color. Azelaic acid helps reduce it.
• Melasma. They are brown spots that appear on the skin. The acid, or products based on it, help to depigment these areas and lighten the skin naturally.

How should it be used?

Azelaic acid comes in the form of a cream, gel, or foam. Instructions for use are printed on the product. It is usually applied twice a day: once in the morning and once in the evening. It is advisable to always do it at the same time to enhance its effect.

The instructions on the label must be followed to the letter, especially when it comes to quantities. The product should not come into contact with the eyes or the mouth. If this happens, remove it with plenty of water. The most advisable thing is to follow these steps:
