Kojic and lactic acid 35% pH 1.6 (chemical peeling)

Kojic and lactic acid 35% pH 1.6 is a preparation for exfoliation treatments. Its main action is to whiten spots and hyperpigmentation and brighten skin tone.

Indications for kojic and lactic acid:

• skin with spots and hyperpigmentation of various origins: lentigines, sun spots, age spots, liver spots, freckles, epidermal melasma
• skin with irregularities requiring levelling, brightening and lightening of discolouration

Effects of kojic and lactic acid:

• bleaching, lightening of skin tone irregularities
• reduction of hyperpigmentation and spots of various origins
• rapid skin tone levelling effects after uneven tanning and post-sun damage
• Particularly recommended if there are a large number of yellowish (to light brown) spots/spots all over the skin

Kojic acid – more information

✓ Kojic acid is an organic chemical compound, produced by fungi – primarily the drosophila. The name ‘kojic’ is derived from the Japanese name for the fungus Aspergillus oryzae – koji. In living organisms, it is produced from sugars, mainly glucose, and is formed by fermentation processes.
✓ Kojic acid has chelating properties, that is, it exhibits the ability to trap metal ions. It has been indicated that this activity prevents photo-ageing of the skin. The results also show that kojic acid reduces wrinkles caused by ultraviolet radiation, prevents skin fibrosis and prevents undesirable changes in the extracellular matrix.
✓ In cosmetics, the most important property of kojic acid is its brightening effect. This is due to its ability to inhibit tyrosinase, the main enzyme responsible for melanin production in living organisms. This property is important in treatments against the signs of skin ageing, which include pigmentation changes such as lentigines, sun spots, age spots, liver spots, freckles, epidermal melasma and other colour irregularities. Kojic acid treatments can brighten the skin and remove hyperpigmentation and spots of various origins.

What do we know about lactic acid?

✓ Lactic acid is an alpha hydroxy acid (AHA) of moderate potency. It plays an important role in biochemical processes. It is produced by lactic acid bacteria of the Lactobacteriaceae family. It is also formed during intense exercise in our muscles and its presence causes acidification of the muscles, which results in reduced performance.
✓ In low concentrations (up to 10%), lactic acid has a moisturising effect – it is one of the main components of NMF, or natural moisturising factor. It therefore influences the hydration and moisturisation of the skin and allows the epidermis to maintain a normal moisture level.
✓ In higher concentrations (usually 30-50%), it has an exfoliating effect. Peelings containing lactic acid also have, in addition to their ability to exfoliate the epidermis, a skin pigmentation-improving effect, for example in facial acne and hyperpigmentation.
✓ Furthermore, lactic acid also shows the ability to increase epidermal thickness by increasing levels of procollagen I and collagen I. Thanks to these properties, it is considered suitable for use in rejuvenating skin with photodamage.
✓ Lactic acid is therefore used very frequently in chemical peel treatments because it effectively stimulates collagen and elastin production. It therefore stimulates skin hydration and elasticity, smoothes wrinkles, lightens spots and discolouration, smoothes scars and stretch marks, and additionally regulates keratinisation, cleanses and shrinks skin pores. To conclude, lactic acid is a mildly effective agent for achieving an all-round improvement in skin condition: hydration, firmness and colour.
