Frequently Asked Questions

Unlike retinol or acids, GHK-Cu and hyaluronic acid don't exfoliate or irritate, so you get real results without the redness or downtime. (As always, we recommend a quick patch test before your first full use.)

Fast. Most people notice smoother, more hydrated skin within days — that's the hyaluronic acid at work. Give it 4–8 weeks of consistent use and you'll start seeing the deeper stuff: firmer texture, a more even tone, and that lit-from-within glow everyone asks about. Of course, results may vary dependent on the individual.

Cleanse — Start with clean, dry (or slightly damp) skin.

Apply — Dispense 2–3 drops into your palm or directly onto fingertips.

Press, don't rub — Gently press the serum into your face and neck, avoiding the eye area.

Follow up — Seal it in with a moisturizer (and SPF if it's your morning routine).

Frequency — Use once or twice daily, morning and/or night, for best results.

Hydration alone isn't enough. Hyaluronic acid floods your skin with moisture, while GHK-Cu goes to work supporting collagen renewal, firmness, and glow — so you're not just quenching your skin, you're actively renewing it. One serum, two powerhouse actives, zero extra steps.

    One Serum. Every Concern.

    What It Targets: Dryness, dullness, fine lines, uneven texture, and that deflated, tired look skin gets when it's running low on moisture and collagen support — this serum was made to take it all on. Hyaluronic acid gets to work fast, flooding skin with hydration and smoothing out rough, dry patches from day one, while GHK-Cu takes it further, supporting your skin's natural renewal process over time to soften the look of fine lines and bring back that firm, bounce-back feel. The result is skin that looks plumper, smoother, and lit-from-within, without stacking five different products to get there.

    Small Steps. Lasting Change.

    Clinical research has shown, GHK-Cu to visibly improve skin hydration, elasticity, and firmness within just 8 weeks of consistent use. That's the standard we formulated to. While hydration starts working from day one, the real transformation happens beneath the surface: GHK-Cu supports your skin's natural collagen and elastin renewal process, the same structural proteins responsible for that firm, bounce-back feel. Eight weeks in, clinical data showed measurable increases in skin thickness, elasticity, and collagen production — not just a temporary glow, but real, structural change.

    Boosts Collagen & Elastin Production

    GHK-Cu works at the cellular level to stimulate collagen and elastin production, helping skin look firmer and more resilient over time.

    Anti-Inflammatory

    Calms inflammation, which can help with overall skin texture and irritation-prone skin.

    Gentle Alternative

    Generally well tolerated with a lower irritation profile than retinoids or strong acids, making it a reasonable option for people who can't handle those actives.

    Due to high demand and ongoing peptide supply chain constraints, CuRenew™ products are at high risk of selling out throughout August-September.

    Dr. Pickart & Dr. Margolina

    "GHK is a safe, inexpensive, extensively studied compound that has a wealth of positive and health-promoting effects in many tissues and systems. It has been widely used in anti-aging and cosmetic products in humans for decades without any adverse effects."

    Dr. Amelia Robinson, Dermatologist (MD)

    "The Finkley 2005 study on 67 women aged 50 to 59 reported improvements in laxity, clarity, firmness, fine lines, wrinkles, and pigmentation across the face after 12 weeks. The best results appear around the eyes, mouth, forehead, and cheeks."
