SEHI-Targeted Enhancement of Hydration: The New Science of Deep Skin Moisture Renewal

When it comes to youthful, radiant skin, hydration is everything. Yet as we age, our skin’s natural ability to hold water steadily declines — often long before visible wrinkles appear. According to the SEHI (Skin Epigenetic Hydroxylation Incompetence) theory, this drop in hydration is not just about surface dryness; it reflects biological aging within your skin cells. Hydration and the SEHI Connection SEHI measures the biological “well-being” of your skin — how fast it is aging based on molecular and cellular markers
