Acids are one of many effective substances used in skin care cosmetic. There are several types of acids designed for different skin types and combating specific dermatological problems.

Properties of cosmetic acids

Cosmetic acid should be treated by anyone who has problems with the complexion. The acids will:

• remove dead epidermis, thanks to which they support the cellular renewal of the skin and improve its hydration and colour,
• remove hyperpigmentations and acne scars,
• cleanse skin pores, have anti-bacterial properties and prevent acne formation,
• prepare the skin for other cosmetic procedures,
• help in the production of hyaluronic acid, collagen and elastin, which are natural substances found in our body,
• can be used on various parts of the body.

Who is acid recommended for?

The acids are of natural origin, so the risk of allergies when in contact with them is very low. Acids are recommended for everyone, regardless of skin type, gender, age or condition. It is important, however, to match the appropriate type and concentration of the product. The use of an acid incompatible with a skin problem can lead to serious complications.

Types of acids 

For cosmetic and beauty purposes, you can enumerate four types of acids:

1. AHA (glycolic, lactic, malic, shikimic and almond) – penetrate deep into the skin. Depending on the concentration, they have exfoliating, cleansing or moisturizing properties. AHA acids will be best for those who struggle with acne or their skin is damaged by excessive tanning and smoking. The recommended concentration should be between 5% and 20%; below this value, AHA acids have a moisturizing effect, and above – irritants.
2. BHA (salicylic acid) – it is obtained from willows, raspberries, roses, birches and chamomile. It cleanses pores, regulates sebaceous glands, and has anti-inflammatory properties. It is recommended for people struggling with acne or blackheads, oily and mixed skin. Salicylic acid does not irritate or dry the skin. The safe concentration of this acid should be chosen by the beautician, and the appropriate pH should be 3-4.
3. LHA (lipo-hydroxy acids, which are derivatives of BHA acids) – cleanse the skin, fight blemishes, reduce the visibility of skin pores. LHA acids are more delicate, so they do not irritate the skin, but have a longer-lasting effect.
4. PHA (poly-hydroxyl) – they work like AHA acids, but unlike them, PHA acids do not cause irritation, flaking of the skin, burning and redness. They penetrate into the epidermis longer, acting slower and more accurately. They will certainly help people with sensitive complexion and those who are suffering from psoriasis, rosacea, seborrhea or eczema. In addition, they moisturize, cleanse and regenerate the hydro-lipid layer.
