What Is Glutamoyl Dipeptide-55 Gamma Tetrapeptide-58?
Glutamoyl Dipeptide-55 Gamma Tetrapeptide-58 is a lab-made peptide that combines a short chain of amino acids with a glutamic acid base. Because it is synthesized rather than taken from animals or plants, it offers a consistent purity that natural extracts sometimes lack. Chemists first explored this type of peptide while looking for stable antioxidants that could also smooth the feel of skin. Over time its dual ability to protect against surface oxidation and leave skin feeling soft made it a natural choice for modern skincare labs.
Manufacturing relies on solid-phase peptide synthesis, a step-by-step process that strings amino acids together in a set order, then attaches the glutamoyl group. Once built, the peptide is purified, dried and blended into cosmetic bases. You will most often find it in lightweight serums, anti-aging creams, sheet masks, overnight treatments and after-sun gels where a boost of soothing antioxidant care is welcome.
Glutamoyl Dipeptide-55 Gamma Tetrapeptide-58’s Cosmetic Benefits/Uses
This ingredient brings two helpful actions to a formula
- Antioxidant: Helps neutralize free radicals on the skin surface which can lessen the look of dullness and limit the appearance of early aging caused by pollution or UV exposure
- Skin conditioning: Leaves a smooth pleasant feel on the skin supports a healthy moisture barrier and can make the overall product glide on more evenly
Who Can Use Glutamoyl Dipeptide-55 Gamma Tetrapeptide-58
This lab made peptide suits most skin types including dry, normal, oily and combination. Its lightweight character means it will not clog pores or leave a heavy feel, so even acne prone or sensitive skin often tolerates it well. At the moment there is no evidence suggesting it is unsuitable for any specific skin type.
Because the molecule is fully synthetic and contains no animal derived material, it aligns with vegan and vegetarian preferences. Manufacturing does not rely on animal testing in regions that ban such practices, though shoppers should still check the brand’s overall cruelty free policy.
Current data shows no known risks to pregnant or breastfeeding women when the peptide is used topically in cosmetic amounts. This is not medical advice and anyone who is expecting or nursing should review any new skincare product with a qualified healthcare professional to be certain it fits their individual needs.
The ingredient does not create photosensitivity, so there is no special sun exposure warning beyond the usual daily SPF recommendation for overall skin health.

Comedogenic Rating
Rating: 0–1 (virtually non comedogenic)
Glutamoyl Dipeptide-55 Gamma Tetrapeptide-58 is a small water soluble peptide used at low percentages that rinses clean without leaving an oily film. It contains no heavy waxes or long chain fatty acids, so it is very unlikely to block pores.
This makes the ingredient a comfortable choice for people who struggle with acne or frequent breakouts.
Remember the final pore clogging potential of any product depends on the rest of the formula, so always glance at the full ingredient list if congestion is a concern.
Summary
Glutamoyl Dipeptide-55 Gamma Tetrapeptide-58 offers two main perks: it scavenges free radicals to defend against early aging and it leaves skin feeling smooth and hydrated thanks to its amino acid structure. Together these actions support a fresher looking, more comfortable complexion.
The peptide is still a niche addition mostly seen in newer anti aging serums, masks and after sun gels rather than mass market moisturizers, but its stability and gentle nature are helping it gain steady traction.
Current research shows it is low risk for irritation or allergy when used in typical cosmetic amounts. Even so, giving any new product a quick patch test is a smart habit to make sure your skin remains happy.
