The Science

SIREN Capsule Technology™

Developed over 10 years of research, discover the adaptive ingredient delivery system that evolves to meet your skin’s changing needs.
GROUNDBREAKING TECHNOLOGY

Powering all U Beauty skincare, multi-patent-pending SIREN Capsule Technology™ revolutionizes the way ingredients interact with your skin—delivering customized treatment for transformative results.

  • 01. Deploy
    First, it deploys biomimetic capsules designed for optimal delivery and absorption that are specifically engineered to perform under stress.
  • 02. Detect
    Next, rather than uniformly saturating the skin with ingredients, Capsules respond to your skin’s individual needs. Like detectives, they help seek out your areas of natural oxidative stress, concentrating ingredient delivery where you require it most.
  • 03. Deliver
    Finally, rather than relying on a single hero ingredient, SIREN Capsule Technology™ delivers curated Capsules with ingredient combinations that are optimized for each product’s purpose.

The Research

Independently validated as a “results oriented breakthrough.”

The Science Behind Smarter Delivery

Published in the Journal of Cosmetic Dermatology, a peer-reviewed medical journal, research on SIREN Capsule Technology™ demonstrated statistically significant results across multiple skin parameters, including: ±​ ​

• Reduced ROS production associated with oxidative stress*
​ • Improved skin hydration and support of the skin's moisture barrier**
​ • Reduced transepidermal water loss (TEWL)**​
• Improved skin texture and visibly reduced appearance of fine lines and wrinkles***​

Free radicals—scientifically known as reactive oxygen species or ROS—are unstable molecules generated by exposure to UV light, pollution, blue light, and normal cellular metabolism. When free radicals overwhelm the skin’s natural defenses, the result is oxidative stress that can show up as dullness, fine lines, and uneven texture. Skincare actives, like antioxidants, help neutralize free radicals.


Most skincare sits on the surface. Siren Capsule Technology™ is designed to deliver actives deeper, precisely targeting the free radical activity that drives visible signs of aging before they appear.
