FARMINGDALE, NEW YORK - November 19, 2025 - A revolutionary breakthrough is transforming the way we fight skin aging. Scientists have developed the world's first at-home test that reveals your skin's true biological age in just five minutes, powered by pioneering SEHI (Skin Epigenetic Hydroxylation Incompetence) and AI technology.

Unlike traditional methods that can take days or even weeks, this test does not rely on superficial indicators like hydration or wrinkles. Instead, it detects the downstream molecular effectors of DNA demethylation, capturing the real functional state of skin aging. The process is simple: a non-invasive adhesive disc is applied to the cheek area, then immersed in a special buffer to generate aging-proportional color signals, which are algorithmically read using the Idunn's Apple Skin Aging Estimator web app with a smartphone camera.

Tightly comparable to gold-standard DNA methylation age assays, this fast and simple method not only rivals laboratory testing but may surpass it by directly measuring the functional drivers of aging.

Once the biological age score is revealed, users receive a personalized skincare recommendation derived from skin age-segmented longevity formulas centered on Idunn Apple's innovative Golden Triple Actives (GTA) formulation. The test allows individuals to identify the regimen best suited to their biological skin age, track improvements over time and adjust treatments as needed, and validate both short-term and long-term results with measurable biological data.

"This marks the beginning of true personalized longevity skincare," said William Lee, CEO of Idunn's Apple. "For the first time, people can reliably and easily measure, monitor, and manage their skin's aging process right from home."

The integration of SEHI-based skin age detection with skin age-tailored treatments sets a new standard in beauty and wellness. It signals a turning point in the cosmetics industry, where skincare is no longer guesswork but precision-driven science that helps individuals achieve their best skin quality.
