£39.99
Professional Strength. Zero Irritation.
Transform your complexion with Kynsson Advanced Retinol 2.5%, our bestselling flagship formula.
This high-concentration serum combines a massive 2.5% dose of Retinol with our proprietary UltraClear technology to resurface, refine, and rejuvenate.
Experience the dramatic results of clinical-grade Vitamin A in a formula that remains light, refreshing, and remarkably gentle on your skin.
Kynsson Advanced Retinol 2.5% isn’t just another serum; it’s a total skin reset. We’ve taken the world’s most proven anti-aging ingredient and optimized it for the modern skincare routine. While most high-strength formulas leave your skin feeling dry and compromised, Kynsson delivers a refreshing, moisture-rich experience.
The Ritual
Apply a small amount to a clean, dry face and neck in the evening.
The Build-Up
If you are new to high-strength retinol, start by using it 2-3 times per week, gradually increasing to nightly use as your skin adapts.
Pro Tip
Always apply a broad-spectrum SPF the following morning, as retinol increases sun sensitivity.
Kynsson uses Slow-Release Liposomal Technology. By encapsulating the pure Retinol in liposomes, we control its release into your skin’s layers.
This “drip-feed” approach maximizes absorbency and effectiveness while minimizing surface irritation.
When combined with our UltraClear pore-clarifying system, the serum works double-duty to repair past damage and protect against future congestion.
Maximum Resurfacing
A potent 2.5% Retinol concentration accelerates cell turnover to visibly smooth deep wrinkles and fine lines.
Proprietary Slow-Release
Our Liposomal delivery system ensures the active ingredients penetrate deep into the skin gradually, preventing the redness and peeling often found in high-strength retinoids.
Blemish & Pore Defense
UltraClear technology unclogs pores and clarifies the skin, preventing future breakouts while refining skin texture.
Deep Hydration
Enriched with Hyaluronic Acid and Shea Butter to lock in moisture and shield the skin from environmental stressors.
