Cosmo ASCORBYL Tetraisopalmitate Solution 10% (30ml) - Serum

Oil-Soluble Vitamin C That Penetrates Deeper

Ascorbyl Tetraisopalmitate (ATP) is one of the most advanced and stable forms of Vitamin C available. Unlike water-soluble Vitamin C derivatives, ATP is oil-soluble — meaning it penetrates the lipid-rich outer layers of the skin more effectively, delivering antioxidant and brightening benefits deeper where they matter most. At 10% concentration, this serum provides meaningful results without the instability or irritation of L-Ascorbic Acid.

What It Does

• Brightens & evens skin tone — inhibits melanin production to fade dark spots and hyperpigmentation
• Antioxidant protection — neutralises free radicals from UV exposure and environmental pollution
• Boosts collagen synthesis — supports firmer, more youthful-looking skin over time
• Deeply penetrating — oil-soluble formula reaches deeper skin layers than water-soluble Vitamin C
• Highly stable — does not oxidise or degrade quickly, ensuring consistent potency
• Non-irritating — suitable for sensitive skin that cannot tolerate L-Ascorbic Acid

Key Ingredient

• Ascorbyl Tetraisopalmitate 10% — a lipophilic Vitamin C ester that converts to active Vitamin C within the skin; highly stable, non-irritating, and more bioavailable than many water-soluble Vitamin C forms

Skin Type

All skin types. Ideal for those with sensitive skin who have experienced irritation with traditional Vitamin C serums. Also excellent for dry or mature skin due to its oil-soluble nature.

How to Use

Apply 2–3 drops to clean skin morning and/or evening before moisturiser. Can be layered with other serums. Follow with SPF during the day for maximum antioxidant benefit.
