Ascorbic C15™

KEY INGREDIENTS:

• L‑Ascorbic Acid (15%): the purest and most active form of vitamin C, with high antioxidant capacity, capable of neutralizing free radicals, inhibiting the tyrosinase enzyme responsible for hyperpigmentation, and stimulating the synthesis of type I and III collagen. Its effectiveness is directly related to its concentration and the formula's pH, optimized here between 3.0 and 3.2 for maximum dermal penetration.
• 5% Glutathione: considered the master antioxidant at the cellular level, it acts as a regenerator of oxidized vitamin C, restoring its active form and reinforcing the skin's antioxidant defense. It also helps to lighten the tone by indirectly inhibiting melanin synthesis, making it an effective biological depigmenting agent.
• 1% Green Tea Extract (Camellia sinensis) provides powerful antioxidant polyphenols that reduce inflammation, soothe the skin, and prevent damage caused by UV rays and environmental pollution.
• Ferulic Acid, a plant-derived phenolic acid, stabilizes vitamin C against oxidation and enhances its antioxidant effect when combined with tocopherol. It also acts as a protective shield against UV radiation and environmental factors, strengthening the barrier function.
• Vitamin E: a lipophilic antioxidant that protects cell membranes from oxidative damage, works synergistically with ascorbic acid to reinforce the skin's antioxidant network, and enhances the photoprotective effect of the overall formula.
• Papaya and pumpkin ferments: gentle enzymatic exfoliants that improve skin texture without causing irritation. They promote cell renewal and prepare the skin surface for better penetration of antioxidant actives.

• Progressive lightening of hyperpigmentation and sun spots.
• Improvement in skin radiance within 2–4 weeks.
• Protection against oxidative damage from UV light and pollution.

• Type: antioxidant anti-aging aqueous serum.
• pH: 3.0–3.2 (optimizes penetration, requires caution on sensitive skin).
• Concentration: 15% pure ascorbic acid.
• Texture: light, aqueous, fast absorption.
• PAO: 3 months after opening.
• Storage: refrigerate (< 5 °C) after opening.
• Complementary antioxidants: glutathione, green tea, ferulic acid, vitamin E (tocopherol).
• Stability: formulated to minimize oxidation in packaging and use.

• Instant brightness and tone unification.
• Visible reduction of fine wrinkles and expression lines.
• Strengthening of the skin barrier and collagen synthesis.
• Anti-aging protection against free radicals.
• Non-greasy feel thanks to its aqueous formulation.
• Paraben and fragrance-free, minimizing irritation (except for acidic pH).

• Why is 15% vitamin C effective?
  Concentrations between 8% and 20% are optimal for penetration and efficacy without saturation
• How do they stabilize such a high content of ascorbic acid in the formula?
  They use an acidic pH (3.0–3.2) and antioxidants like glutathione and green tea to counteract oxidation
• What role does glutathione play?
  It restores the active form of oxidized vitamin C, amplifying antioxidant capacity.
• Who is it not suitable for?
  It is not recommended for very sensitive skin due to its low pH; they might prefer gentler vitamin C derivatives
• Why refrigerate it and how long does it last?
  Ascorbic acid is very unstable; the PAO is 3 months and it should be kept below 5°C after opening
• When to apply in the routine?
  Recommended in the morning, on clean skin, ideally before sunscreen.
