What Is S-Black Widow Spider Pentapeptide-1 Sp?
S-Black Widow Spider Pentapeptide-1 Sp is a lab-made mini protein made of five amino acids. Scientists copied a tiny portion of alpha-latrotoxin, a larger protein found in the venom of the black widow spider, then produced it through standard peptide synthesis rather than extracting it from spiders. The result is a clean, vegan-friendly ingredient with no animal material. Interest in bio-inspired peptides took off in the early 2000s when researchers noticed that short chains of amino acids could signal skin cells to act younger or hold more moisture. This particular peptide entered cosmetic labs soon after thanks to its clever mix of protection and conditioning benefits.
To make it, chemists string together the five amino acids on a solid support, then purify the finished chain until it reaches cosmetic grade. Because it is water soluble and stable, formulators can slip it into both water-based and emulsion systems without fuss.
You will most often spot S-Black Widow Spider Pentapeptide-1 Sp in anti-aging serums, eye creams, leave-on masks, moisturizers, lash conditioning treatments and after-sun products where an extra hit of protection and hydration is welcome.

Who Can Use S-Black Widow Spider Pentapeptide-1 Sp
This peptide is lightweight water based and non-occlusive so it suits dry balanced combination oily and even sensitive skin. Because it helps bind water without heavy oils it can hydrate acne-prone complexions without clogging pores. No particular skin type must avoid it; only those with a proven allergy to peptides should proceed cautiously.
S-Black Widow Spider Pentapeptide-1 Sp is entirely man-made and contains no animal material or by-products which makes it appropriate for both vegans and vegetarians. Most suppliers also certify it as cruelty-free since no spiders are harmed during production.
Current safety data suggest it is low risk for pregnant or breastfeeding women when used topically in cosmetic amounts. Still this is not medical advice and anyone who is expecting or nursing should discuss every skincare product with a qualified healthcare professional before use.
The ingredient does not increase photosensitivity so it will not make skin more prone to sunburn. Standard daytime sun protection is still recommended for overall skin health.
Potential Side Effects/Adverse Reactions
Responses to topical S-Black Widow Spider Pentapeptide-1 Sp differ from person to person. The issues below are possible but uncommon when the peptide is used at normal cosmetic levels.
- Transient redness or warmth
- Mild stinging or tingling on very sensitive skin
- Localised itching or rash indicating an allergic reaction
- Eye irritation if a lash serum migrates into the eye
If any irritation or discomfort develops stop using the product and seek guidance from a healthcare professional.
Comedogenic Rating
Rating: 0/5 – S-Black Widow Spider Pentapeptide-1 Sp is a tiny water-soluble peptide with no oils or waxes so it does not block pores or encourage the buildup that can lead to blackheads. The molecule glides on, absorbs quickly and leaves no heavy film, which keeps congestion risk extremely low.
That makes it a friendly option for people who struggle with acne or frequent breakouts.
Keep in mind that a finished product’s overall pore-clogging potential depends on the full formula. If the same serum also contains rich butters or heavy silicones, those other ingredients, not the peptide itself, could raise the comedogenic load.
Summary
S-Black Widow Spider Pentapeptide-1 Sp is a lab-crafted five-amino-acid chain that acts as an antioxidant, humectant, skin protector, skin conditioner and lash strengthener. It scavenges free radicals, pulls moisture into the surface layers, forms a light shield against daily stress and smooths both skin and lashes for a softer feel.
While not a household name like hyaluronic acid, it is quietly gaining traction in targeted serums, eye creams and lash treatments because formulators appreciate its multitasking abilities and vegan origin.
Current data show it is low-irritation and non-comedogenic, with only rare reports of sensitivity. As with any new cosmetic active, patch test first to be sure your skin agrees before applying it to a larger area.
