What Is Anacardoyl Sh-Pentapeptide-39 Tripeptide-1?
Anacardoyl Sh-Pentapeptide-39 Tripeptide-1 is a lab-crafted peptide complex that marries short chains of amino acids with anacardic acid, a natural compound originally isolated from cashew nutshells. Chemists link the peptide fragments to the lipid-like anacardoyl group, creating a molecule that can slip easily into the skin’s upper layers while carrying active benefits.
The ingredient first surfaced in advanced skincare research during the early 2010s when formulators were searching for gentler alternatives to traditional brightening agents. By combining a plant-derived antioxidant with skin-friendly peptides, they achieved a multi-tasking component suitable for daily products.
Manufacturing starts with fermenting specific bacteria to produce the base peptides. Separately, anacardic acid is refined from leftover cashew shells collected by the food industry. Through a controlled coupling reaction, the acid is attached to the peptide chain, followed by purification and stabilization so the compound stays active in creams and serums.
You will most often spot Anacardoyl Sh-Pentapeptide-39 Tripeptide-1 in brightening serums, anti-aging moisturizers, sheet masks, eye creams and post-sun repair treatments where a soothing antioxidant boost is desired.
Anacardoyl Sh-Pentapeptide-39 Tripeptide-1’s Cosmetic Benefits/Uses
Here is how this multi-functional ingredient supports healthier looking skin
- Antioxidant – helps neutralize free radicals created by UV light and pollution which can otherwise accelerate the look of aging
- Bleaching – gently interferes with excess melanin production, aiding in the fading of dark spots for a more even tone
- Skin Protecting – forms a light defensive film on the surface, improving barrier function and reducing moisture loss throughout the day
Who Can Use Anacardoyl Sh-Pentapeptide-39 Tripeptide-1
This peptide–lipid hybrid suits most skin types, including dry, combination, oily and sensitive skin, because it is lightweight and non-greasy yet calming. Extremely reactive or allergy-prone skin should proceed with extra care since the molecule contains a cashew-derived component that could be troublesome for anyone with a known tree-nut allergy.
The ingredient is produced through plant leftovers and microbial fermentation, with no animal by-products, making it appropriate for vegans and vegetarians.
No data points to risks for pregnant or breastfeeding women when the ingredient is used topically at typical cosmetic levels. That said, this is not medical advice and anyone expecting or nursing should show the full ingredient list to their healthcare provider before use just to be safe.
Anacardoyl Sh-Pentapeptide-39 Tripeptide-1 does not increase photosensitivity, so it can be applied morning or night, though daily sunscreen is still recommended for overall skin health.
Potential Side Effects/Adverse Reactions
Responses to topical Anacardoyl Sh-Pentapeptide-39 Tripeptide-1 vary by individual. The points below outline potential but uncommon issues. When the ingredient is formulated correctly most users experience none of these problems.
- Mild stinging or warmth on very sensitive skin
- Temporary redness or flushing after application
- Allergic reaction in people with a cashew or tree-nut allergy
- Rare itching or hive-like bumps due to peptide sensitivity
If any of these reactions appear stop using the product and consult a healthcare professional.
Comedogenic Rating
Rating: 1/5 (very low)
Anacardoyl Sh-Pentapeptide-39 Tripeptide-1 is primarily a small peptide blended with a lightweight fatty chain, so it does not build the heavy, waxy layer that typically clogs pores. Laboratory stability tests show it disperses evenly in water-based or light emulsions rather than sitting on the surface like thicker oils, keeping its pore-blocking potential minimal.
Because of this low rating, the ingredient is generally suitable for acne-prone or breakout-prone skin when used in well-formulated products. Its final impact still depends on the full recipe, so rich creams that contain other comedogenic oils could change the overall pore-clogging outcome.
Summary
Anacardoyl Sh-Pentapeptide-39 Tripeptide-1 delivers antioxidant, brightening and protective benefits in one tidy molecule. The peptide segment signals skin to stay resilient while the anacardoyl portion shields cells from free radicals and lightly slows excess pigment production, leading to a calmer tone and stronger moisture barrier.
Although not yet a household name, the ingredient is popping up in targeted serums and eye creams as brands look for modern alternatives to harsher lighteners. It is considered safe at cosmetic levels with low irritation risk for most users, though anyone with tree-nut allergies should stay alert. As with any new skincare addition, patch testing a small area first is a smart step before full use.
