What is Argireline?
Argireline is the trade name for a synthetic cosmetic peptide made of six amino acids. Its sequence is written Ac-Glu-Glu-Met-Gln-Arg-Arg-NH2, with an acetyl group on one end and an amide on the other. On ingredient lists it was first named acetyl hexapeptide-3; the name was later updated to acetyl hexapeptide-8, and you will see both on labels today. That is why searches for argireline, argireline hexapeptide 8 and argireline peptide all lead to the same ingredient.
Like SNAP-8, its design is based on a short fragment of SNAP-25, a protein found in nerve endings. The Argireline peptide is formulated into skincare: an argireline serum, cream, eye product or a simple water-based solution. This page explains the product form, how label strength is written and how it relates to similar cosmetic peptides. It makes no claims about effects on skin.
Can you mix Argireline with BAC water?
No, and there is no need to. Bacteriostatic water is used to dissolve freeze-dried powders in sealed vials that are meant to be drawn into a syringe. Argireline is a cosmetic ingredient for products applied to the skin. Finished serums and creams already contain it at the strength the manufacturer chose, so there is nothing to reconstitute and no U-100 syringe-unit math. That is why the calculator on this page is greyed out.
Some suppliers sell argireline powder or a concentrated ingredient solution for cosmetic formulating. That is raw material for making a topical product, not a research vial for syringe use, and adding BAC water to it does not change that. For what bacteriostatic water is actually designed for, see our guide to BAC water.
Argireline peptide injection: why this site has no injection information
Some people search for “argireline peptide injection,” often because the ingredient is described in marketing next to injectable cosmetic treatments. Argireline is a cosmetic ingredient intended for topical products. It is not sold as an approved injectable, and this site gives no injection information for it: no amounts, no mixing ratios and no syringe math.
The same stance applies to every page here. We only do arithmetic on an amount someone already has in a reconstituted vial, and we never set, suggest or check an amount. For a topical ingredient there is no such arithmetic to do. Questions about using any product belong with the product labeling and a qualified professional.
Reading an argireline serum or “solution 10%” label
Topical products state strength as a percentage rather than mg in a vial. A few pure unit facts make those labels readable:
- Percent by weight: 1% means 1 g of an ingredient per 100 g of product, which is the same as 10 mg per gram.
- Ingredient solution vs pure peptide: Argireline is usually supplied to manufacturers as a dilute ingredient solution. A label such as “argireline solution 10%” normally means 10% of that ingredient solution, not 10% pure acetyl hexapeptide-8.
- Ingredient list order: ingredients are listed roughly from most to least, so position gives a rough idea of amount when no percentage is stated.
Because of the solution-versus-peptide difference, two products with the same headline percentage are not necessarily the same strength. Read the wording on each label, and do not compare a percentage with a powder weight until both are in the same unit.
Argireline benefits and before-and-after claims
“Argireline benefits” and “argireline before and after” are popular searches, and product listings often answer them with photos and promises. This site does not evaluate or repeat those claims. Neutrally stated, Argireline is a cosmetic peptide that has attracted research interest because of its SNAP-25-based design, and it is marketed in products aimed at the look of the skin.
Before-and-after images in listings are marketing material; they are not something a calculator or a label can verify. What a label can tell you is the ingredient name and, sometimes, a percentage. That is the part of the product this page explains.
Argireline vs SNAP-8
Argireline has a close relative: SNAP-8 (acetyl octapeptide-3). SNAP-8 takes the Argireline sequence and adds two amino acids, making an eight-amino-acid peptide instead of six. Both are topical cosmetic ingredients, both are sold in serums and creams, and they often appear together in the same formula.
On a label the difference is the name: acetyl hexapeptide-8 or -3 for Argireline, acetyl octapeptide-3 for SNAP-8. Neither is reconstituted, and this page does not compare them for results.
Regulatory status of Argireline
Acetyl hexapeptide-8 is a cosmetic ingredient, not an FDA-approved drug. Cosmetics in the United States do not go through drug approval, and products containing Argireline are sold as cosmetics for topical use. It is not labeled for injection.
Because it is a topical ingredient rather than a reconstituted vial, Argireline sits outside the calculators on this site. For peptides that are sold as freeze-dried powder and need BAC water math, browse the peptide library, where each page includes a mixing chart and a calculator.
Argireline (Acetyl Hexapeptide-8) FAQ
What is Argireline?
Argireline is the trade name for acetyl hexapeptide-8, originally listed as acetyl hexapeptide-3. It is a synthetic six-amino-acid peptide used as an ingredient in topical serums and creams.
Can you mix Argireline with BAC water?
No. Argireline is a cosmetic ingredient for topical products, not a freeze-dried injectable vial. There is nothing to reconstitute, so BAC water and syringe-unit math do not apply.
What does argireline solution 10% mean?
It usually means the product contains 10% of an Argireline ingredient solution, not 10% pure peptide. Percent by weight means grams per 100 g of product.
Is Argireline the same as acetyl hexapeptide-3?
Yes. Acetyl hexapeptide-3 was the original ingredient name, later updated to acetyl hexapeptide-8. Both names refer to the same peptide.
Does this site give argireline injection information?
No. Argireline is a cosmetic ingredient for topical use, and this site gives no injection amounts, mixing ratios or syringe math for it.
What is the difference between Argireline and SNAP-8?
SNAP-8 extends the six-amino-acid Argireline sequence by two amino acids, making acetyl octapeptide-3. Both are topical cosmetic ingredients.
