How It Works
How It Works
Siren Capsules
SIREN Capsule Technology
A proprietary ingredient delivery system that utilizes free radicals for targeted benefits: SIREN Capsules activate where the visible effects of free radicals accumulate—while avoiding the exposure of harsh ingredients to areas that don't need treatment, cleverly avoiding associated side effects, like dryness and irritation.
Each SIREN Capsule is packed with a strategic blend of antioxidants, hyaluronic acids, peptides, probiotics, and more to address the skin's unique needs for transformative-looking results.
