Tripeptide-1 Peptide Solution is an odorless, water-soluble liquid peptide (INCI: Tripeptide-1) for serums, creams and lotions positioned for firmer, smoother and more elastic-looking skin. The recommended concentration is 0.5 to 2%, which makes even small bottles last. Choose from seven sizes: a 10 mL sample, 1 oz, 4 oz, 8 oz, 16 oz, 32 oz and 1 gal (3.78 L).
What Is Tripeptide-1?
Tripeptide-1 is a synthetic peptide built from three amino acids: glycine, histidine and lysine. This listing supplies it in solution, so use the specifications of the liquid, not those of an isolated powder, and plan with the full composition and active concentration of the supplied solution. Note that Tripeptide-1 is not the same as Copper Tripeptide-1, which is a different ingredient identity.
Why Choose Tripeptide-1
Firm and elastic-looking skin
The peptide is used in creams, serums and lotions aimed at a softer look of fine lines and visibly firmer, more elastic skin.
Hydrated appearance
The current product text also describes a plumper, well-hydrated look in finished products.
Easy to work with
The solution is odorless and soluble in water, so it does not affect the scent of your product.
Applications
Tripeptide-1 goes into face serums, day and night creams and lotions. For a copper-complexed alternative, look at Copper Peptide (GHK) Peptide Solution; for a peptide pair with firmness positioning, see Matrixyl 3000 Peptide Solution. Browse everything in the active ingredients category.
How to Use
Add Tripeptide-1 at 0.5 to 2% and make sure it is fully dissolved in the aqueous phase. Check the active concentration of the supplied solution and test the complete product for stability before production. For more detail, read our guide Tripeptide-1 in a DIY Tanning Spray: Recipe and Tips.
Compatibility
As a water-soluble material, it fits gels, serums and the water phase of emulsions, for example with a hyaluronic acid gel base. Match the INCI on your label to the material you actually use.
Dosing example
A 100 g serum built with 1 g of solution leaves most of the bottle untouched, so a 1 oz bottle covers many trial batches and a gallon serves full production.
Liquid, not powder
Because this is a solution, its active concentration differs from an isolated Tripeptide-1 powder. Always read the composition of the supplied liquid before you plan percentages, and never reuse a powder figure for this product.
Writing the label
List Tripeptide-1 by its INCI and keep claims to smoother, firmer and more hydrated-looking skin that your own finished-product testing supports.

I have been using skincare products formulated with Tripeptide-1 for the past six months, and the results are incredible. My skin’s elasticity has improved significantly, and the fine lines around my eyes and mouth have visibly reduced. What I love most is how my skin feels firmer and more hydrated. It’s a game-changer for anyone looking to combat aging signs effectively.

Tripeptide-1 has become an essential part of my skincare routine. After incorporating it into my serums and creams, I’ve noticed a remarkable difference in my skin’s texture and tone. The wrinkles on my forehead and around my eyes are much less noticeable, and my skin looks and feels smoother. Plus, it’s gentle enough for my sensitive skin. Highly recommend this peptide for anyone seeking youthful, radiant skin!

I’ve tried dozens of serums, but nothing gave me the same feeling as Tripeptide-1. My skin feels firmer, more elastic, and just… refreshed. I especially noticed the difference around my jawline — it feels tighter without any dryness. So happy I found this peptide!

This peptide is amazing! I’ve been using Tripeptide-1 for about two weeks and already see glow and bounce in my skin. It feels so soft and smooth — and it layers great under makeup too. Definitely keeping this in my daily routine.

At my age, finding something that actually helps with sagging skin is rare. But Tripeptide-1 surprised me. My cheeks feel lifted, and fine lines are less obvious. I feel more confident without makeup — that says a lot!
