Professional cosmetic acids - support for all skin types
Professional cosmetic acids and their use
Cosmetic acids are chemical compounds with a wide range of applications in cosmetology. Thanks to these substances, you can achieve the effect of rejuvenated, revitalized skin, as well as reduce the number of wrinkles and changes causing unpleasant symptoms. Professional cosmetic acids are also used in dermatology offices to reduce irritation. Their action also supports the fight against skin diseases, including: with acne.
Types of cosmetic acids
To understand the action of these substances, it is worth first knowing the groups into which cosmetic acids are divided. The types differ in many respects, including: in matters of construction, application and properties. There are three main substances: α-hydroxy acids (AHA), β-hydroxy acids (BHA) and polyhydroxy acids (PHA).
Characteristics of AHA, PHA and BHA cosmetic acids
Cosmetic acids, depending on their action and use, can exfoliate the epidermis, remove lesions and acne scars, unclog pores and stimulate the production of elastin and collagen. Thanks to them, the skin absorbs more nutrients and minerals.
AHA acid is a fruit acid. It is used in beauty and dermatology salons, but it can also be used at home as an ingredient of DIY cosmetics. The most popular of them include almond acid,lactic acid, glycolic acid, malic acid, tartaric acid.
For example: glycolic acid, thanks to a molecule larger than a water molecule, can penetrate deep layers of the skin. Thanks to this, it exfoliates the epidermis and helps reduce wrinkles. Regardless of whether the reason for their occurrence is too frequent, intense sunbathing or aging of the skin, the substance visibly elasticizes and tightens the skin.
PHA acid is one of the gentlest acids available - it usually does not cause irritation or sensitization. This compound is especially recommended for people with sensitive, delicate skin. The most commonly used PHA acids include:gluconolactone and lactobionic acid.
For example: lactobionic acid has a soothing and anti-inflammatory effect. This is due to the presence of a galactose molecule. This compound softens and smoothes the epidermis, soothes redness and increases the protective barrier. Additionally, it accelerates the healing process, so it is suitable for skin prone to irritation.
BHA acid dissolves creatine found in the skin. This means that it loosens the cells, thanks to which the dead skin peels off. In addition, this compound affects pores and therefore helps fight blackheads. The most popular BHA acid is salicylic acid obtained from willow or birch bark.
Who can use cosmetic acids?
Although cosmetic acids have many healing properties for the skin, there are contraindications to their use. In the case of the PHA group, there are fewer of them - these substances do not irritate as much as the others. Both shikimic acid, as well as almond acidIt cannot be used in the presence of serious inflammation or visible tissue damage.
Lactobionic acid causes side effects in people suffering from atopic dermatitis, rosacea or dermatitis. In addition, it is not recommended to use the preparation in pregnant women. Allergy to the described substance is also a contraindication.
How to use cosmetic acids?
Facial skin cleansing should always be well thought out and tailored to the needs of the skin. Cosmetics such as serum, peeling, micellar fluid or gel with acids can be used every day, but all exfoliating treatments should be performed no more than once a week. It is also worth paying attention to compounds that are used in the summer because they do not cause photosensitivity - these include: mandelic acid, azelaic acid, shikimic acid, phytic acid, malic acid.
Too frequent treatments, shaving or sunbathing may cause body irritation. If this happens, it is worth choosing delicate cosmetics containing cosmetic acids from the Lynia brand.
