EyeSeryl Peptide Booster
Anti-Aging Peptide for Puffy Eyes Acetyl Tetrapeptide-5
If your eyes are beginning to look a little puffy, Eyeseryl® peptide solution helps reduce the accumulation of fluid trapped in the under-eye area.
EyeSeryl is Acetyl Tetrapeptide-5, a peptide booster used at 1 to 10% in eye formulas for the look of smoother, less puffy under-eyes.
This is a formulation ingredient, not a finished serum. Do not apply it undiluted.
What is in the bottle
INCI: Glycerin, Water (Aqua), Acetyl Tetrapeptide-5
Three ingredients. Supplied as Solution G, preservative-free and paraben-free, in a 0.5 oz blue glass dropper bottle.
Because it contains no preservative, add one to your finished blend — Leucidal Liquid or Leucidal Complete at 2–4% — and keep it refrigerated.
How much to add
Recommended usage rate is 1 to 10%. Using our house rate of 9 drops per 1% per fluid ounce:

What the supplier's research reports
In the manufacturer's clinical testing — 20 women aged 18 to 65 — 70% showed at least a 30% improvement by day 15, and 95% showed improvement by day 60, measured on the appearance of under-eye puffiness.
These findings are the manufacturer's, from their efficacy dossier, and are reproduced here under our licence agreement with them. They describe testing of the raw material rather than of a finished blend, so your result depends on the concentration you use and how consistently you apply it.
How to use it
- Choose a light eye gel, serum or cream as your base.
- Add the drops for the percentage you want.
- Add a preservative at 2–4%.
- Cap, shake well, and refrigerate.
- Apply cold, morning and night, patting gently around the orbital bone. Keep it out of the eye itself.
Applying it cold helps. A blend straight from the fridge feels better on tired eyes than one at room temperature.
What to pair it with
EyeSeryl handles the look of puffiness. For the look of under-eye shadows, add Haloxyl at 1–3% to the same formula — the two are commonly used together in eye products.

Questions & Answers
Eyeseryl is indeed a potent peptide known for its efficacy in reducing puffiness and dark circles around the eyes. However, when it comes to adding active ingredients like Eyeseryl to an existing product, it's crucial to ensure that the concentration is correct to achieve the desired effects without compromising the stability or safety of the product.
We recommend following the manufacturer's guidelines for adding any active ingredient to a pre-made base or finished product. This ensures that you achieve an effective and safe concentration.
Eyeseryl inhibits glycation, this is what happens when too much sugar is consumed. AGE's or Advanced glycation endproducts cause premature aging and the breakdown of collagen and elastin. So yes, your face and neck serum would benefit from Eyeseryl.
