ALPHA-H | Liquid Gold

1. Glycolic Acid (5%)
Mechanism: Acts as a chemical exfoliant by breaking the intercorneocyte cohesion bonds in the stratum corneum, promoting selective desquamation and accelerating cell turnover.

Biological Effect: It indirectly stimulates the synthesis of glycosaminoglycans (GAGs) and dermal collagen by activating membrane receptors in dermal fibroblasts. It has moderate hygroscopic capacity and promotes water retention in the stratum corneum.

2. Licorice Extract (Glycyrrhiza glabra Root Extract)

Mechanism: Inhibits tyrosinase, reducing melanin synthesis, and acts as a natural anti-inflammatory agent thanks to its high glabridin content.

Biological Effect: Reduces erythema induced by exfoliants and prevents post-inflammatory hyperpigmentation, particularly in sensitive skin or higher phototypes (III–V).

3. Proteins of Silk (Hydrolyzed Silk)

Mechanism: Low molecular weight peptides with high affinity for skin keratin, forming a semi-permeable moisturizing film.

Biological Effect: It promotes water retention, reduces transepidermal water loss (TEWL), and improves surface texture after exfoliation.

4. Glycerin
Mechanism: Physiological moisturizer that forms hydrogen bonds with water molecules, improving the hydration of the stratum corneum.

Biological Effect: Prevents dehydration secondary to the use of exfoliating acids and protects the integrity of the barrier function.

• Apply to completely clean skin, without any previous occlusive products.
• Use preferably at night to avoid photoinstability of AHAs.
• Avoid simultaneous application with retinoids or mechanical exfoliants; alternate on different nights.
• Do not apply on areas with open wounds or active dermatitis.
• The use of broad-spectrum sunscreen (SPF 50+) during the day is mandatory.
  
  
  
  
  
  
  

• In 3 nights: Visible increase in skin brightness and improvement in dermal tone, resulting from the controlled shedding of corneal cells.
• At 2 weeks: Increase in surface smoothness, with a decrease in microreliefs and tactile roughness (epidermal refining effect).
• At 4–8 weeks: Noticeable reduction of post-inflammatory hyperpigmentation (PIH), solar lentigines, and fine lines; increase in dermal firmness and elasticity due to the stimulation of type I and III collagen by the indirect action of glycolic acid on dermal fibroblasts.
• Cumulative results: In the long term, the skin shows greater color uniformity, improved dermal density, and an optimal balance between exfoliation and repair.
  
  

• Physiologically compatible acidic pH (2.5–3.0) that promotes the ionization of glycolic acid, optimizing its intracellular penetration.
• Anhydrous formula for rapid absorption, without fragrances or drying alcohols.
• Synergistic action between exfoliation, antioxidation, and biostimulation.
• Minimalist design without harsh surfactants, suitable for frequent use on skin prone to breakouts, discolorations, or signs of premature aging.
• Galenic stability guaranteed through opaque packaging and preservation in recycled PCR polymers.
  
  
  
  
  
  

• Promotes controlled epidermal renewal
• Visibly improves skin texture and smoothness
• Stimulates the production of endogenous collagen, elastin, and hyaluronic acid
• Provides radiance and a more even skin tone
• Minimizes fine lines, enlarged pores, and mild discoloration
• Retains moisture thanks to humectant ingredients
• Reduces exfoliation-induced redness thanks to licorice extract
• Facilitates the penetration of subsequent treatments

• Can I use it with sensitive skin?
  Yes, but use caution initially: start by applying it only 1–2 nights a week and monitor your skin's tolerance. If you experience persistent burning or excessive peeling, reduce the frequency or discontinue use.
• Can I use it in the morning?
  It is recommended for use only at night, as glycolic acid increases skin photosensitivity and its effectiveness may be reduced if combined with daytime products.
• Can it be used daily?
  No. Initially, it should be used on alternate nights. Depending on your skin's tolerance, the frequency could be increased to 3–4 nights a week, but not every night.
• Can it be combined with retinoids or other exfoliating active ingredients?
  It should be used with caution: alternate nights of glycolic acid with nights of retinol, or space out their use. Do not apply them simultaneously to avoid over-exfoliation.
• Is it safe during pregnancy or breastfeeding?
  Depending on the brand, it is suitable for use during pregnancy and breastfeeding.
• When will I see results?
  Depending on the brand: visible improvement in radiance after 3 nights, and more significant improvements in texture and tone in about 3 weeks.
• How long does it last once opened?
  Follow the PAO on the packaging (usually 6 to 12 months) and keep it in a cool place away from direct light.
