What is Medex a-Hycid Gel 10% and who is it for?

Medex a-Hycid Gel 10% is a professional-grade AHA exfoliating gel formulated with 100% natural fruit acids — L-Lactic Acid, Sodium Citrate and L-Tartaric Acid — at an optimal pH of 3.8. It's designed for both teenagers and adults who want to refine skin texture, even out skin tone and restore a smoother, more youthful-looking complexion.

How do I use Medex a-Hycid Gel 10% in my skincare routine?

Apply a thin, even layer of Medex a-Hycid Gel 10% to clean, dry skin once daily, preferably in the evening. Avoid the eye area and mucous membranes and leave it on — no rinsing needed. If you're new to AHAs, start with 2–3 applications per week and gradually increase frequency as your skin adjusts.

What does Medex a-Hycid Gel 10% actually do for my skin?

Medex a-Hycid Gel 10% accelerates the skin's natural cell renewal process, leaving skin noticeably smoother, softer and more radiant. L-Lactic Acid exfoliates at the cellular level and helps inhibit pigment production by targeting the enzyme Tyrosinase. It also stimulates ceramide biosynthesis, which strengthens the lipid barrier and helps lock in moisture.

Is Medex a-Hycid Gel 10% suitable for sensitive or first-time AHA users?

Yes — Medex recommends starting with just 2–3 applications per week so your skin can gradually adjust to the fruit acids. If sensitivity occurs, you can rinse the gel off rather than leaving it on. The lightweight gel texture and precisely calibrated pH of 3.8 are designed to optimise efficacy while supporting the skin's barrier function.

What makes Medex a-Hycid Gel 10% different from other AHA products?

Medex a-Hycid Gel 10% combines three naturally derived fruit acids — L-Lactic Acid, Sodium Citrate and L-Tartaric Acid — that work synergistically for both exfoliation and antioxidant protection. It's free from silicones, paraffin oil and microplastics, and packaged in glass, making it a more conscious choice for your skin and the environment.

Description

Medex a-Hycid Gel 10% pH 3.8 is a professional-grade AHA gel formulated with naturally occurring fruit acids that actively support the skin's own renewal process. Powered by a precisely balanced blend of L-Lactic Acid, Sodium Citrate and L-Tartaric Acid at an optimal pH of 3.8, this lightweight gel helps resurface the skin, leaving it noticeably smoother, softer and more radiant. L-Lactic Acid — the hero ingredient — exfoliates at the cellular level, stimulates new epidermal cell formation and targets uneven skin tone by inhibiting the enzyme Tyrosinase, which drives pigment production. It also boosts ceramide biosynthesis, strengthening the skin's lipid barrier and helping to lock in moisture. L-Tartaric Acid, a double AHA with potent antioxidant properties, adds an extra layer of protection to the barrier function, while Sodium Citrate refines skin texture and neutralises free radicals. This fruit acid gel is suitable for both teenagers and adults looking to refine their complexion, reduce the appearance of uneven tone and restore a youthful, supple texture. Free from silicones, paraffin oil and microplastics, and packaged in glass — a conscious choice for your skin and the planet. Add Medex a-Hycid Gel to your routine and let nature do the work.

Operation

The alpha-hydroxy acids in this gel — L-lactic acid, sodium citrate and L-tartaric acid — work synergistically at a cellular level. They accelerate the skin's natural cell renewal process in the epidermis, promoting a smoother and more radiant skin surface. L-lactic acid also inhibits the enzyme tyrosinase, curbing pigment formation right from the first step. At the same time, it stimulates ceramide biosynthesis, reinforcing the lipid barrier and preventing moisture loss. The antioxidant properties of sodium citrate and L-tartaric acid protect skin cells from oxidative stress. The precisely calibrated pH of 3.8 optimises the bioavailability of the acids for maximum efficacy.

Application

Apply a thin, even layer of a-Hycid Gel 10% to clean, dry skin once daily, preferably in the evening. Gently smooth over the face, avoiding the eye area and mucous membranes. Leave on as directed — do not rinse off unless sensitivity occurs. Start with 2–3 applications per week and build up frequency as your skin adjusts. Keep out of reach of children.

Ingredients

L-Lactic Acid: L-Lactic Acid is an alpha-hydroxy acid found in various fruits such as tomatoes and dairy products like yogurt. It is the natural stereo-isomer, also commonly found in the human body. L-Lactic Acid has exfoliating properties, particularly in higher concentrations, and stimulates new cell formation in the epidermis. It is particularly effective at targeting hyperpigmentation, providing better results compared to other alpha-hydroxy acids like glycolic acid. L-Lactic Acid also inhibits the enzyme Tyrosinase, which plays a key role in pigment production, thus preventing the first step of pigmentation in the skin. Additionally, L-Lactic Acid stimulates the biosynthesis of ceramides, which strengthens the skin’s lipid barrier, helping to prevent dryness.

Sodium Citrate: Sodium Citrate is the trisodium salt of citric acid, an alpha-hydroxy acid with antioxidant properties. Found in various plants and citrus fruits, it stimulates the production of new skin cells and is also used to adjust the acidity of skincare products.

L-Tartaric Acid: L-Tartaric Acid, found in old wine, is a double alpha-hydroxy acid. Historical use of wine in skincare dates back to the court of King Louis XIV, where women unknowingly benefited from its presence. L-Tartaric Acid provides exfoliating effects in higher concentrations, stimulates new cell formation in the epidermis, and offers significant protection to the skin’s barrier function due to its antioxidant properties.
