Your Skin's Rewind Button | NEW A1 Serum

Retinoids (vitamin A derivatives like Retinol and Retinal) are long-proven skincare heroes to keep skin youthful, smooth, radiant and clear – benefits optimised by our exclusive TTS³ technology in the new Clinic A1 Vitamin A Power 1 serum.

What does this mean for your skin? Greater results and long-term skin health without barrier disruption. And the best part is you don’t need to navigate confusing or misleading percentage levels. Instead, TTS³ has allowed us to boost formula performance and strength via supercharged actives, ultra-targeted delivery and increased skin absorption – not increased levels of actives. 

As a result of this intelligent approach to retinoids, signs of natural and photo-induced skin ageing are transformed: fine lines and wrinkles are diminished, tone and texture are more even, skin is lifted and firmer, and a healthy, youthful smoothness is restored. 

Unique, performance-boosting technology

Our exclusive TTS³ technology supercharges A1 in three ways:

1. SYNERGISTIC INGREDIENTS: It unlocks a powerful synergy between Retinol, Retinal and EGF Peptide Growth Factor to boost and prolong the effects of vitamin A;
2. BIOAVAILABLE DELIVERY: Using a pharma-proven deep delivery system, TTS³ increases the serum's bioavailability, making the hero actives up to 20x more effective;
3. BIOMIMETIC BASE: To improve ingredient absorption without compromising your barrier function, TTS³ includes a biomimetic lamellar emulsion that mirrors the skin's natural structure.

Time-tested skin-regenerating actives

By effectively reaching targeted skin sites to perform their intended functions, A1's synergistic group of actives – RETINOL, RETINAL and EGF – act to improve skin's appearance and overall health, minimising signs of ageing and boosting firmness for a more youthful look.

While the two forms of vitamin A (Retinol + Retinal) plump up the skin and smooth fine lines and wrinkles, their synergistic partner, EGF Peptide Growth Factor, acts to enhance their effects on the skin, supporting skin's natural regeneration in the process.
