ZO Skin Health Growth Factor Serum
ZO Skin Health Growth Factor Serum is a lightweight anti-ageing growth factor serum, relaunched for 2026 as a new formula in a new blue jar. It is clinically shown to improve the appearance of skin thickness and elasticity, and results in skin that appears 6 years younger after 8 weeks of use (based on an average of subject assessments). For skin that is starting to look thinner, less supple and more lined, it restores the look of plumper, more hydrated skin.
The reformulated ZO Skin Health Growth Factor Serum pairs ZO's Human-Comparable Growth Factor Technology with plant- and enzymatically-derived growth factors to restore the appearance of skin density, compactness and visible strength. ZPRO®, a protein complex, boosts hydration and collagen to visibly strengthen the skin's structure, while the peptide dipeptide diaminobutyroyl benzylamide diacetate temporarily reduces the look of expression lines. In an independent 12-week study of 46 women aged 44 to 74, 100% agreed skin looked lifted and supported, and instrumental testing measured a 16% improvement in elasticity and a 26% improvement in hydration.

Becci is a registered aesthetics nurse with more than two decades in specialist skincare and medical aesthetics, and her clients have long relied on her for straight answers about which serums are worth the money. She recommends this one because the study behind the new blue jar formula is independent, uses instrument measurements as well as opinions, and was run on skin with genuine signs of ageing, so what she tells clients to expect is grounded in data rather than marketing.
