ZO Growth Factor Serum
Denser, firmer-looking skin, powered by growth factors.
Growth Factor Serum uses two growth factors to support your skin's own collagen and elastin, building density and firmness over time. The lightweight formula absorbs cleanly and helps skin look smoother, plumper, and more resilient with consistent use.
Why it is worth it
Growth factors are among the most respected anti-aging ingredients for rebuilding skin quality, and this delivers them in a gentle, daily formula almost anyone can tolerate. It is one of ZO's most reordered serums.
How it compares
Pair it with Daily Power Defense for an unbeatable daily base. For pure resurfacing, add a retinol like Wrinkle + Texture Repair. Growth Factor Serum is the firmness and density specialist.
Best for: loss of firmness, density, and overall skin quality, on all skin types.
Not ideal for: those focused only on acne or pigment.
How to use
Apply to clean skin morning and night, before your moisturizer.
