The skincare industry is enormous, and most of it operates at the surface. Moisturizers hydrate the outer layers of skin. Retinoids stimulate collagen production and accelerate cell turnover. Antioxidant serums neutralize free radicals at the skin’s surface. Sunscreens prevent UV damage.
All of these have value. But they all operate on the skin from the outside. What determines the long-term health and appearance of your skin is largely what’s happening at the cellular level — inside the skin cells themselves.
Skin cells face significant oxidative stress. UV radiation, pollution, and normal metabolic activity all generate free radicals that damage skin cell DNA, proteins, and membranes. Your body’s response to this damage is coordinated by the same redox signaling system that coordinates immune response, cellular repair, and antioxidant activation throughout the body.
When redox signaling is functioning well, skin cells repair UV and oxidative damage efficiently. Fibroblasts — the cells that produce collagen and elastin — receive the signals they need to maintain production. Stem cells in the skin receive signals that guide normal cell renewal. The inflammatory responses that produce persistent redness and damage are regulated and resolved.
When redox signaling declines with age, these processes slow. Damage accumulates faster than it’s repaired. Collagen production decreases not just because the raw materials are lacking, but because the signals that trigger production are less reliable. The result is the visible accelerated aging that no topical product can fully address — because the problem is inside the cells, not on their surface.
ASEA produces a topical skin care line called RENUAdvanced that applies redox signaling molecules directly to the skin. The concept is to support cellular signaling at the site where the damage occurs — giving skin cells the signaling support they need to activate their own repair and renewal processes.
Good skin health starts from the inside. What happens at the cellular level determines what shows on the surface.
