FAQ

We prioritize scientifically backed “active” ingredients with proven efficacy but known instability in cosmetic formulations. Many studies on these actives used fresh samples rather than shelf-stable products. Our formulas focus on meaningful concentrations to target five key skin concerns:

• Vitamin C (L-ascorbic acid): Brightens discoloration and sun damage
• Retinol: Reduces lines and wrinkles
• CoQ10: Firms and repairs skin
• Green Tea & Resveratrol: Strengthen aging, sensitive skin

Probiotics & Enzymes: Refine pores and clear blemishes

We only perform clinical testing with measured instrumentation-- which uses advanced devices to objectively quantify skin improvements, such as hydration, firmness, and wrinkle reduction, ensuring accurate, reproducible results. In contrast, consumer perception testing relies on subjective feedback from participants who self-assess visible or sensory changes in their skin, which may be influenced by personal experience and expectation rather than measurable data.
