A. Product Introduction

In Lab Medical Acid Clean is an elite professional-grade exfoliating toner. Within the landscape of international clinical aesthetics, the "toning and preparation" phase is recognized as the essential foundation for any successful skin transformation. This product is positioned as a Biological Dermal Purifier, specifically engineered to bridge the gap between aggressive chemical peels and daily skin maintenance.

The formulation concept is built around the "Smart Exfoliation" principle. Unlike standard over-the-counter toners that rely on harsh alcohols or high-concentration single acids, Acid Clean utilizes a multi-pathway approach. It synergizes Polyhydroxy Acids (PHAs) with a stabilized 3% concentration of Niacinamide. Designed for both professional clinical use—as a preparatory step for advanced facial protocols—and for intensive consumer home care, it targets the "Urban Skin" profile: a complexion frequently compromised by traffic pollution, environmental toxins, and metabolic slowing.

B. Active Ingredients & Mechanism of Action

The scientific superiority of Acid Clean lies in its quantitative synergy of chemical, enzymatic, and biological exfoliants, providing a comprehensive solution for skin homogenization.

The PHA Advantage: Gluconolactone

At the heart of the formula is Gluconolactone. In cosmetic science, PHAs are celebrated for their "slow-release" exfoliation. Because the molecule is larger than Glycolic Acid, it stays on the skin surface longer, removing dead cells without triggering the inflammatory response often seen in sensitive skin. Furthermore, Gluconolactone contains multiple hydroxyl groups, which attract water into the epidermis, ensuring that the peeling process is accompanied by intensive hydro-restoration.

Barrier Integration with 3% Niacinamide

A standout feature of this toner is the high-standard concentration of Niacinamide. In the context of an exfoliating product, Vitamin B3 serves a critical dual purpose:

1. Barrier Reinforcement: It stimulates the synthesis of ceramides, ensuring the skin remains resilient even as the outer layer is refined.
2. Pore Refinement: It helps regulate sebum quality and inhibits the transfer of pigment, effectively reducing the visibility of blackheads and post-inflammatory marks.

Botanical and Multi-Acid Synergy

The inclusion of Lactic, Citric, and Malic acids provides a multi-depth resurfacing effect. This is further enhanced by Ananas Sativus (Pineapple) extract, which contains the enzyme bromelain. Bromelain selectively digests the proteins in dead skin cells, smoothing the micro-relief of the skin and revealing a "lit-from-within" radiance that characterizes youthful tissue.

C. Indications & Application Protocol

In Lab Medical Acid Clean is indicated for high-performance corrective treatments targeting the following aesthetic concerns:

• Dull and Sallow Complexions: Specifically formulated for "smoker's skin" or skin lacking vitality due to urban pollution.
• Follicular Congestion and Blackheads: Ideal for refining skin with dilated pores and visible impurities.
• Photo-Aging and Textural Irregularities: Recommended for smoothing fine lines and reducing superficial pigmentary discontinuities.
• Daily Environmental Defense: Acts as a biological shield that removes fine particulate matter (PM 2.5) before it can trigger "inflammaging."

Application Protocol: This is a leave-on treatment intended for daily use.

1. Impregnate a cotton pad with the solution.
2. Apply uniformly to the face, neck, and décolleté after cleansing.
3. Do not rub excessively.
4. Allow the solution to air-dry before applying subsequent In Lab Medical active serums.

• Crucial Note: While PHAs are less photosensitizing than AHAs, the daily use of In Lab Medical Safe Sun 50+ is mandatory during treatment.
