The peptide trio that actually makes sense
Most anti-ageing routines pile on actives and hope something sticks. Peptide skincare works better when each ingredient has a job.
That is why Rlabs built the range around three well-known cosmetic peptides:
GHK-Cu (Copper Tripeptide-1) — supports the look of firmness, smoothness and repaired-looking texture
SNAP-8 (Acetyl Octapeptide-3) — helps soften the appearance of expression lines
Glutathione — antioxidant support for a brighter, more even-looking complexion
They are not interchangeable. Used together, they cover structure, movement lines and glow.
What GHK-Cu is for
GHK-Cu is a copper-binding tripeptide used in cosmetic formulas to support the appearance of firmer, more resilient-looking skin, smoother texture and clarity, and a healthier-looking barrier after daily stress.
It is the “rebuild the look of the skin” peptide in the stack. That is why it sits in our SNAP-8 + GHK-Cu Serum.
What SNAP-8 is for
SNAP-8 is a topical peptide used to help reduce the look of dynamic lines — the ones that show up from smiling, frowning and squinting. Think crow’s feet, forehead lines and frown lines.
It does a different job to GHK-Cu. One is about the look of skin structure. The other is about the look of expression lines. That is why they pair well in one lightweight serum.
What glutathione is for
Glutathione is the glow piece. In our Glutathione Beauty Bundle the serum and cream are built to support a brighter, more radiant-looking complexion, help the look of more even tone, defend the skin’s appearance against everyday environmental stress, and lock in moisture so skin looks plump, not tight.
If GHK-Cu and SNAP-8 are the “smooth and firm” pair, glutathione is the “illuminate” pair.
A simple AM / PM routine
Morning
1. Cleanse
2. Rlabs Glutathione Serum — press in, do not rub hard
3. SNAP-8 + GHK-Cu Serum on forehead, between brows and around eyes
4. Glutathione Cream
5. SPF
Night
1. Cleanse
2. SNAP-8 + GHK-Cu Serum
3. Glutathione Cream
Give it 4–8 weeks of consistent use. Peptide cosmetics reward the people who apply them like brushing their teeth.
How to apply so it does not pill
Use 2–4 drops of each serum. More product does not mean more result. Wait 30–60 seconds between layers. Press, do not drag, around the eyes. If you use a strong acid or retinoid, put peptides on clean skin and keep acids on alternate nights until you know how your skin feels.
Who this routine is for
You want the look of smoother expression lines without jumping straight to clinic treatments. Your skin looks dull, uneven or tired. You want a short Australian peptide routine instead of a 12-step shelf.
