The real problem
If your skin looks tired, textured, or uneven — even when your routine is "doing everything right" — the problem usually isn't effort. It's the wrong kind of active.
Uneven texture
Dull, tired look
Early fine lines
Makeup won't sit right
The mechanism
Why copper peptides — without the drama.
Copper Tripeptide-1 (GHK-Cu) is a copper-bound peptide used in skincare to support the look of firmness, texture, and evenness. CuLab contains 1% Copper Tripeptide-1 in the finished formula, in a peptide-focused approach without the exfoliating action of retinoids or acids.
- Supports the look of firmer, bouncier skin
- Visibly smoother, more even tone over time
- Comfortable next to actives, or on its own
Individual results vary. Not intended to treat any medical condition.

Benefits
A serious step. Zero fuss.
Helps skin look smoother, more even, and more awake
Contains 1% Copper Tripeptide-1 in the finished formula, working with your skin's natural renewal process so texture looks refined.
Supports bounce and firmness without a harsh routine
A peptide-focused approach without the exfoliating action of retinoids or acids — just a consistent, gentle step toward firmer-looking skin.
Gives makeup a better-looking base
A smoother canvas means foundation sits evenly instead of catching on rough patches.
Feels comfortable on reactive or actives-cautious skin
Formulated for people who've been burned by strong acids or retinol before — this is the calmer alternative.
Easy to layer under moisturiser and SPF
Fits into your existing routine easily — no waiting, no special order to follow.
A serious peptide step that never feels sticky or fussy
Lightweight and fast-absorbing, so it never gets in the way of the rest of your routine.
One serious step. Not another bottle in the pile.
Most routines get crowded fast — a shelf of half-used bottles, unclear labels, and steps you can't quite justify. CuLab keeps it clear: one peptide serum, one honest ingredient list, one simple step you can actually stick to.
Lightweight.
Fast-absorbing.
Zero stickiness.
A watery-gel serum designed to absorb quickly with a lightweight finish — no tacky feel, no pilling under SPF. A concentrated peptide formula with a lightweight daily finish.
How to use
Three steps. Morning and night.
Who it's for
Serious results without the harsh-routine drama.
Made for anyone who wants a real, ingredient-literate step — especially if retinol, strong acids, or unstable vitamin C haven't worked for you.
Real routines, real CuLab
Loved by real routines
People are noticing.
"My cheek texture looks smoother and makeup sits so much better."
"Finally something between 'boring moisturiser' and 'irritating retinol'. My skin looks awake."
"No sting, no pilling. I use it under SPF every morning."
"I stopped chasing new actives. This is the only serum I've kept in the routine."
The honest comparison
How CuLab May Fit Into Your Routine
| CuLab GHK-Cu | Retinol | Strong Vitamin C | |
|---|---|---|---|
| Type of step | Designed as a gentle peptide step | Retinoid active | Antioxidant active |
| Exfoliating action | No exfoliating or retinoid active | Increases cell turnover | Can be acidic at high strengths |
| Ease of layering | Designed to layer easily | Often restrictive | Often order-sensitive |
| What to expect | Gradual, steady with consistent use | May involve an adjustment period | Varies by formulation |
Individual tolerance varies. Retinoids and vitamin C are well-established ingredients and may work well for many people. CuLab is designed for customers seeking a peptide-focused alternative or complementary routine step.
