SKYN condoms are highly effective at preventing both pregnancy and sexually transmitted infections, performing on par with traditional latex condoms in clinical testing. Made from polyisoprene (a synthetic version of the rubber found in latex), they provide the same barrier protection without the proteins that trigger latex allergies.
How SKYN Condoms Compare to Latex in Clinical Tests
The most concrete way to measure condom performance is through breakage and slippage rates during actual use. In an FDA-reviewed clinical trial involving over 267 couples, polyisoprene condoms had a clinical breakage rate of 1.3%, compared to 0.7% for natural rubber latex condoms. The slippage rate was identical for both materials at 0.6%.
That slightly higher breakage rate sounds concerning on paper, but both numbers are well within the range the FDA considers acceptable for condom clearance. In practical terms, the difference amounts to roughly one additional break per 167 uses. Both materials passed the same burst pressure and volume tests required under international safety standards (ISO 23409), meaning SKYN condoms are held to the same physical durability benchmarks as any other condom on the market.
Pregnancy Prevention
Condoms as a category, whether latex or polyisoprene, are about 98% effective at preventing pregnancy with perfect use and around 87% effective with typical use. That gap exists because “typical use” accounts for real-world mistakes: putting the condom on late, using the wrong size, or not leaving space at the tip. The material itself is not the weak link. Since polyisoprene and latex have nearly identical breakage and slippage profiles, the pregnancy prevention rates are functionally the same for both.
If you’re using SKYN condoms consistently and correctly, you can expect the same level of pregnancy protection you’d get from any well-fitting latex condom.
STI Protection
Polyisoprene is an effective barrier against the pathogens that cause most sexually transmitted infections. Used correctly, condoms made from this material are more than 90% effective against chlamydia, gonorrhea, hepatitis B, and HIV. The synthetic material blocks viral and bacterial particles just as latex does, with no meaningful difference in permeability.
The limitation is the same one that applies to every external condom: they only protect the skin they cover. Infections spread through skin-to-skin contact, like genital herpes, genital warts, and syphilis, can still be transmitted through areas the condom doesn’t reach. This is a design limitation, not a material one.
The Latex Allergy Advantage
The biggest practical reason people choose SKYN over standard latex is sensitivity or allergy. Natural rubber latex contains proteins from the Hevea brasiliensis tree that can trigger reactions ranging from mild itching and redness to serious allergic responses. Polyisoprene is synthesized in a lab and does not contain these proteins, making it a safe choice for anyone with a confirmed or suspected latex allergy.
Unlike polyurethane condoms (another latex-free option), polyisoprene stretches and feels more like natural rubber. This is why SKYN markets heavily on the “feels natural” angle. The material is softer and more elastic than polyurethane, which tends to feel stiffer and can crinkle during use. For people switching away from latex for allergy reasons, polyisoprene is the closest match in terms of sensation and fit.
Lubricant Compatibility
SKYN condoms are compatible with water-based and silicone-based lubricants. Oil-based products, including body lotions, baby oil, petroleum jelly, and even cooking oils, will degrade the polyisoprene material and compromise the condom’s integrity. This is the same restriction that applies to latex condoms, so if you’re switching from latex to SKYN, your existing lube collection should work fine as long as it’s not oil-based.
SKYN’s own branded lubricants are formulated for compatibility with their condoms, but any water-based or silicone-based product from another brand will work equally well.
What Actually Affects Performance
The material of a condom matters far less than how it’s used. The most common reasons condoms fail have nothing to do with whether they’re latex or polyisoprene. Using the wrong size is the biggest factor: a condom that’s too tight is more likely to break, and one that’s too loose is more likely to slip off. SKYN offers several size options for this reason.
Other factors that reduce effectiveness include storing condoms in hot environments (like a car glove box or wallet for extended periods), using expired condoms, opening the wrapper with teeth or scissors, and not pinching the tip before rolling it on. With any condom, correct technique closes most of the gap between typical-use and perfect-use effectiveness rates.
