What Is Galloyl Sh-Pentapeptide-19?
Galloyl Sh-Pentapeptide-19 is a lab-crafted molecule created by linking galloyl chloride, a plant-derived antioxidant source, with Sh-Pentapeptide-19, a synthetic chain of five amino acids. The galloyl part lends strong free-radical fighting power while the peptide segment is valued for its ability to communicate with skin. Developers began exploring this hybrid in the early 2010s while searching for gentler alternatives to harsh preservatives and have since refined its production through controlled condensation reactions done at low temperatures to protect peptide integrity. After purification and stabilizing steps the finished ingredient appears as a fine powder ready for formulation. Today you will mainly see Galloyl Sh-Pentapeptide-19 in leave-on anti-aging serums, daily moisturizers focused on environmental defense, sheet masks and eye treatments where brands want to pair antioxidant support with skin conditioning benefits.
Galloyl Sh-Pentapeptide-19’s Cosmetic Benefits/Uses
This ingredient offers a focused duo of benefits that help bolster many modern skincare formulas.
- Antioxidant: It helps neutralize free radicals generated by UV light and pollution which in turn supports a brighter more even-toned complexion and can slow the look of premature wrinkles.
- Skin protecting: By reinforcing the skin’s natural barrier and reducing oxidative stress it can make skin more resilient to daily aggressors helping maintain softness and comfort.
Who Can Use Galloyl Sh-Pentapeptide-19
Because it is lightweight and non-comedogenic Galloyl Sh-Pentapeptide-19 suits most skin types including dry, oily or combination. Sensitive skin also tends to tolerate it well thanks to its gentle antioxidant profile though anyone with a known sensitivity to peptides or galloyl compounds should approach with caution.
The ingredient is produced through plant-derived galloyl chloride and a lab-synthesized peptide with no animal inputs making it appropriate for vegans and vegetarians. Manufacturers typically use synthetic or plant-based stabilizers so animal by-products are not part of the standard supply chain.
There is no research indicating specific risks for pregnant or breastfeeding women when this molecule is applied topically, yet data is limited. This information is not medical advice and anyone expecting or nursing should have a doctor review their skincare routine before adding products that contain Galloyl Sh-Pentapeptide-19 just to stay on the safe side.
The molecule does not increase photosensitivity. In fact its antioxidant action can help defend against sunlight-generated free radicals, though daily sunscreen is still essential for overall protection.
Galloyl Sh-Pentapeptide-19 layers well with common actives like niacinamide or hyaluronic acid and does not interfere with the vast majority of over-the-counter treatments.
Potential Side Effects/Adverse Reactions
Responses to topical Galloyl Sh-Pentapeptide-19 differ from person to person. The points below outline potential side effects that could occur, yet they are uncommon when the ingredient is formulated and used correctly.
- Mild redness or warmth especially on very sensitive skin during first uses
- Transient tingling or stinging around the eye contour if applied too close to the lash line
- Itchiness or dry patches if layered with overly strong exfoliants or retinoids
- Contact dermatitis in rare cases of allergy to peptides or phenolic compounds
- Watery eyes if the product migrates into the ocular area
If any of these reactions occur stop use and consult a healthcare professional for guidance.
Comedogenic Rating
Rating: 0/5
Galloyl Sh-Pentapeptide-19 is a small water-soluble molecule that does not leave an occlusive film on skin and contains no heavy oils or waxes that could block pores. Formulators typically use it at low concentrations inside lightweight serums and lotions, further reducing any clogging risk. Because of these factors its comedogenic rating is considered 0.
This makes the ingredient suitable for people prone to acne or frequent breakouts.
As with any formula the overall pore-friendliness of a finished product depends on the full ingredient list, so always assess the complete formulation if congestion is a concern.
Summary
Galloyl Sh-Pentapeptide-19 offers two core benefits: antioxidant defense and skin protection. The galloyl segment donates electrons to neutralize free radicals created by UV light and pollution while the pentapeptide portion can signal skin to reinforce its barrier, together helping maintain a smoother more resilient complexion.
You will mostly find this hybrid active in targeted anti-aging or environmental shield products rather than everyday cleansers, so its presence on ingredient lists is still niche but growing as brands look for multifunctional actives that remain gentle.
Current research and user reports suggest it is safe for regular topical use with only rare irritation. As with any new skincare addition patch testing is a smart step to ensure personal compatibility.
