i’m not anti-makeup. love a good lip moment. but i used to need foundation to feel presentable and that always kind of bothered me.

six months into GHK-Cu and i barely touch it anymore. here’s the whole story.

what even is GHK-Cu?

it’s a copper peptide that your body naturally produces — but levels drop hard after your twenties. it does a bunch of things: stimulates collagen (type I and III), promotes elastin, activates wound healing, and has antioxidant properties that protect against UV damage.

basically it’s your skin’s favorite molecule and you’re making less of it every year. fun!

how i use it

every evening: GHK-Cu serum after cleansing. face, neck, backs of hands. i look for formulations at 1-3% concentration.

occasionally: i’ve also done a 4-week injectable cycle at 200mcg/day for a more intensive skin-repair phase. not necessary for most people — the topical alone does a lot.

what changed (real timeline)

  • weeks 1-2: nothing visible. skin maybe slightly smoother to the touch
  • weeks 3-4: texture improvement. pores started looking smaller
  • month 2: other people started noticing. “your skin looks good, what changed?”
  • month 3-6: fine lines around eyes softened. overall tone way more even. the “glow” is real, it just takes time

the hair thing i didn’t expect

i wasn’t using it for hair. but around month 3 i noticed baby hairs along my hairline where nothing had been happening in years. also feels thicker at the root. could be placebo. could be the copper peptide. either way — not complaining.

my full evening skincare

  1. oil cleanse (for SPF + any makeup)
  2. gentle water cleanser
  3. GHK-Cu serum (wait 2 min)
  4. niacinamide
  5. ceramide moisturizer
  6. retinol 3x/week (alternating with GHK-Cu nights)

where i get mine

i’ve tried a few vendors and settled on one i trust — research-grade, proper COAs, consistent across orders. if you want to know where, just DM me.

who this is for

if you’re in your twenties: topical is enough. think of it as investing in future you.

if you’re 30+: this is one of the most well-supported peptide interventions for skin that isn’t retinol or a laser. worth trying.
