Lactic and mandelic acid 33% pH 1.4 (chemical peeling)

Lactic and Mandelic Acid 33% pH 1.4 is a formulation for lifting exfoliation treatments. Rejuvenating, moisturising, anti-wrinkle, reducing the network of fine wrinkles.

Indications for lactic and mandelic acid:

• mature skin, flabby, thinning, lacking elasticity and resilience
• pronounced signs of ageing, network of fine wrinkles
• pigmentation spots
• extremely dry, flaky skin with a “caking effect”
• polluted skin, with blackheads, grey, without radiance
• keratosis disorder

Effects of lactic acid and mandelic acid:

• stimulation of elastic fibre production
• significant improvement in skin parameters such as elasticity, firmness and resilience
• Hydration, regulation of hydro-lipid balance

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.

Lactic acid – more information

✓ Mandelic acid is an alpha hydroxy acid (AHA) found in nature in bitter almonds. It exhibits a mild exfoliating action, even though its potency is slightly greater than that of glycolic acid. This is due to the slightly larger size of its molecule, as well as its greater affinity for the skin’s lipid barrier. The penetration of mandelic acid into the skin is gradual, but effective and easily controlled.

✓ It therefore has a mild exfoliating effect, and its beneficial effects on the skin are the reduction of signs of photo-ageing and uneven pigmentation, the levelling of acne symptoms and wrinkles.

✓ It has also been shown to have antibacterial effects on such bacterial strains as Staphylococcus aureus, Bacillus proteus, Escherichia coli and Aerobacter aerogenes.

✓ Studies have confirmed the effect of mandelic acid on regulation of sebum secretion. Mandelic acid causes pigmentation lightening and is an agent used in peels for skin pigmentation disorders.

✓ Mandelic acid has a superficial action and acts on the outer layers of the epidermis. The mechanism of repair action includes stimulation of fibroblasts for increased synthesis of collagen, elastin and glycosaminoglycans.
