Using this growth factor serum at the wrong time isn’t just wasteful — it could literally cancel out the collagen you’re trying to build. Peptides and growth factors hate UV light like I hate a bad lash lift.
Morning application works, but only if you’re militant about SPF 50+ on top. Miss that step and the $200+ serum is basically just expensive moisturizer.
Zo Skin Health calls this a “bio-engineered growth factor complex” — I call it the most expensive thing on my vanity at $225 for 1 oz. The claim that got me: “restores skin’s repair capacity.” Fine, take my money.
Growth Factor Complex
Re-engineered human proteins that tell your skin to act young again.
Peptide Matrix
Signals collagen production without the irritation of retinol.
Antioxidant Cocktail
Stabilizes the formula so it doesn’t oxidize after three weeks.

Three hero ingredients do the heavy lifting here: EGF (epidermal growth factor) for cell turnover, copper peptides for wound healing, and niacinamide for barrier support. No fragrance, no essential oils — it’s clinical, not cute.
- EGF: Speeds cell turnover without peeling
- Copper Peptides: Repairs micro-damage from sun/environment
- Niacinamide: Calms inflammation + supports barrier
- Sodium Hyaluronate: Hydration without the sticky film

Texture is a lightweight gel-cream that absorbs in about 12 seconds — no residue, no pilling under sunscreen. Smells like nothing, which I actually prefer.
Week 2: I tried AM only for five days. Skin looked fine but nothing special. Switched to PM only — woke up with noticeably firmer texture around day 5. The difference was real enough that I texted my derm: “night use wins.”

After 4 weeks of PM-only use: fine lines around my mouth softened by maybe 20%, skin looked less “tired” in the mornings. Pores? Same size. Hydration? Great — but I also use a moisturizer over it.

This serum earns its price tag — but only if you use it at night. Morning application is marketing, not science.
