Resveratrol is a powerful antioxidant found naturally in grapes, berries, and red wine, and one of the most compelling longevity ingredients in modern skincare. Its primary mechanism is the activation of sirtuins, reparative proteins within the skin's DNA that govern cellular repair and longevity. As sirtuin activity declines with age, skin loses its ability to recover efficiently from environmental damage. Resveratrol helps restore that signaling, visibly reducing fine lines, improving firmness, and supporting long-term skin vitality at a cellular level.
Exponent's Calm Revival preserves Resveratrol in powder form until the moment of activation, protecting it from the oxidative degradation that compromises pre-mixed formulas before they ever reach your skin.

Retinol is the gold standard over-the-counter form of vitamin A, and the most clinically proven ingredient available without a prescription for accelerating cell turnover, resurfacing skin, and reducing the visible signs of aging. Most people avoid it because of the irritation reputation– retinol causes redness, dryness, flakiness, purging. That reputation is a formulation problem, not an ingredient problem.
Exponent's Time Rewind uses 0.25% Retinol, equivalent in strength to a starter prescription dose of 0.025% Tretinoin, preserved as a dry powder without the inflaming stabilizers found in conventional retinol formulas. Activated fresh at the moment of use and buffered with hyaluronic acid, it delivers prescription-level results without the irritation, peeling, or tolerance adjustment period most retinol users expect. It can be used every night by even sensitive skin types.
