What are AHAs and how do they affect the skin?

AHAs (Alpha-Hydroxy Acids) are acids of natural or synthetic origin, widely used in cosmetics for their exfoliating and brightening properties. Mainly derived from fruit, milk or sugar cane, they include molecules such asglycolic acid,lactic acid,citric acid andmalic acid.

Their action is based on their ability to dissolve the bonds between dead cells on the skin's surface, encouraging their natural elimination. This process renews the epidermis, improving skin texture, reducing pigmentation spots and stimulating collagen production for smoother, more luminous skin.

What are the benefits of AHAs for the skin?

AHAs are prized for their multiple benefits, making them essential active ingredients in anti-aging skincare, exfoliating products and anti-imperfection treatments. Their main benefits include

• Gentle exfoliation: elimination of dead cells for a more radiant, even complexion.
• Improved skin texture: reduction of dilated pores, acne scars and skin irregularities.
• Reduced wrinkles and fine lines: collagen stimulation for firmer, plumper skin.
• Reinforced hydration: increases skin's capacity to retainwater, particularly withlactic acid.
• Depigmenting action: fades brown spots, melasma and traces ofhyperpigmentation.
• Blemish reduction: fights pimples, blackheads andexcess sebum.

What types of AHA exist, and how do I choose the right one?

There are several types ofAHA, each with specific properties adapted to the skin's needs:

• Glycolic acid (derived from sugar cane): the most powerful AHA, it promotes cell renewal and acts deep down to reduce wrinkles and smooth the skin.
• Lactic acid (from milk): known for its moisturizing properties, ideal for sensitive or dehydrated skin.
• Citric acid (from citrus fruit): brings immediate radiance to the complexion and has antioxidant properties.
• Malic acid (from apples): acts as a gentle exfoliant and stimulates skin regeneration.
• Mandelic acid (from almonds): has an antibacterial action, perfect for skin prone to imperfections.

Choosing theideal AHA depends on your skin type and beauty goals. For anti-aging action,glycolic acid is recommended, while for intense hydration,lactic acid is more suitable.

Are AHAs suitable for all skin types?

AHAs are suitable for all skin types, but their concentration and frequency of use must be adapted according to skin sensitivity.

• Dry and sensitive skin: prefer mild AHAs such aslactic acid, and apply them in low concentrations (less than 5%).
• Normal to combination skin:glycolic acid is effective for smoothing skin and refining texture.
• Oily and blemish-prone skin:mandelic acid orglycolic acid are recommended to regulateexcess sebum and limit pimples.

It's essential to gradually integrate AHAs into your routine to avoid irritation and excessive desquamation.

How do I incorporate AHAs into my beauty routine?

To reap the full benefits of AHAs, we recommend following an appropriate routine:

• Gentle cleansing: use a cleanser without aggressive agents to avoid weakening the skin.
• Application of AHA skincare products: serums, lotions or creams, always on clean, dry skin.
• Essential moisturizing: apply a cream rich in soothing agents to protect the cutaneous barrier.
• Mandatory sun protection: AHAs increase sensitivity to UV rays, so an SPF 50 sun cream is essential during the day.

It is advisable to use AHAs in the evening, as their exfoliating action can make the skin more reactive to the sun.

What are the side effects of AHAs and how can they be avoided?

Although AHAs are well-tolerated, they can cause certain undesirable effects, particularly if their concentration is too high or if they are used too frequently:

• Redness and irritation: a sign of skin sensitivity, applications should be spaced out.
• Excessive desquamation: too intense a peel can lead to dry, peeling skin.
• Increased sensitivity to the sun: UV exposure can cause pigmentation spots if the skin is not protected.

To avoid these side effects, start with a low concentration and always apply sunscreen during the day.
