AHA (lactic acid, citric acid, glycolic acid)

Lactic acid
INCI name: Lactic Acid

What is lactic acid?
Lactic acid is a versatile organic acid that plays an important role in biochemical processes and has wide application possibilities in various fields of industry. Its use in the cosmetic and food industries is particularly significant, and it is popular as an AHA used in skin care. It is produced by fermentation from plants (sugar beets, sugar cane, potatoes), fruits (apples, grapes) and milk. This is the most common method because it offers a natural and sustainable solution.

The effect of lactic acid on the skin:
It helps remove dead skin cells, resulting in a smoother and brighter skin surface. Lactic acid has natural moisturizing properties, as it can bind water in the skin, thereby improving skin hydration. With regular use, it can help even out skin tone, reduce pigmentation and improve skin texture. Due to its pore-cleansing effect, it reduces the chance of developing blackheads and acne. Lactic acid also has anti-inflammatory properties, so it can help improve the condition of inflamed skin.

Important!!!
In order to minimize skin reactions, gradually introduce it into the skin care routine, especially in case of sensitive skin. Rarely, an allergic reaction or sensitivity to lactic acid may occur.
Can be irritating in high concentrations!

Citric acid
INCI name: Citric Acid

What is citric acid?
Citric acid is an organic acid with many properties and applications. It is usually produced by fermentation, most often from sugar-containing raw materials (e.g. corn, sugar beet) with the help of lactic acid bacteria. Its use helps to maintain the optimal pH value of cosmetic products, which is important for the product's stability and effectiveness. A versatile ingredient that contributes to the effectiveness of modern skin care products with its beneficial effects and wide application.

The effect of citric acid on the skin:
Citric acid helps remove dead skin cells from the surface of the skin, resulting in smoother and brighter skin. Regular use can improve skin texture and tone.
It has natural moisturizing properties, helping the skin's ability to retain water, which contributes to the hydration of the skin. It can neutralize free radicals, so it can contribute to slowing down the aging of the skin. It inhibits the growth of certain bacteria and fungi, thereby helping to prevent skin infections.

Important!!!
Although citric acid is generally safe, high concentrations can cause skin irritation. Especially for sensitive skin, so it is worth gradually introducing it into the skin care routine.

Glycolic acid
INCI name: Glycolic Acid

What is glycolic acid?
An alpha hydroxy acid that is most often used in skin care products. It is produced from sugar cane and fruits through a fermentation process or through chemical synthesis. It is a good pH regulator and solvent in industrial preparations.

The effect of glycolic acid on the skin:
Thanks to its small molecules, glycolic acid is able to penetrate into the deeper layers of the skin, where it stimulates collagen production, thereby improving skin elasticity and reducing the depth of wrinkles. Its skin-exfoliating and cell-renewing effect helps in the fight against pigment spots and wrinkles.
It is found in many skin care products because of its ability to bind water in the skin.

Important!!!
When using glycolic acid, irritation, redness or sensitivity may occur, especially at higher concentrations. Adequate sun protection is required during application, as the skin may become more sensitive to sunlight!
