SKYN condoms are not made of latex. They’re made of polyisoprene, a synthetic rubber that mimics the stretch and feel of natural rubber latex but doesn’t contain the proteins responsible for latex allergies. If you’re searching because you or a partner has a latex allergy, SKYN condoms are a safe alternative.
What Polyisoprene Actually Is
Natural rubber latex comes from the sap of rubber trees and contains proteins that trigger allergic reactions in some people. Polyisoprene is chemically similar in structure, which is why it stretches and feels comparable to latex, but it’s manufactured synthetically. That manufacturing process eliminates the natural proteins that cause Type I latex allergies. The result is a material that behaves like latex during use but is safe for people who react to it.
Polyisoprene is actually stretchier than standard latex, which is part of why SKYN markets its condoms as having a more natural, skin-like feel. This is a distinct material from polyurethane, which is the other common non-latex condom material and tends to feel thinner and less elastic.
How They Compare to Latex in Protection
Polyisoprene condoms are cleared by the FDA for both pregnancy prevention and STI protection, but they go through a rigorous approval process to get there. Non-latex condoms must demonstrate in clinical trials that their safety and effectiveness are substantially equivalent to legally marketed latex condoms, including breakage and slippage testing with statistically valid sample sizes.
In practice, polyisoprene condoms do show slightly higher breakage rates than latex. A randomized controlled clinical trial found that non-latex condoms had a combined breakage or slippage rate of 4.0% during the first five uses, compared to 1.3% for latex condoms. The breakage rate specifically was about eight times higher for the non-latex condom. The six-cycle typical-use pregnancy rate was 10.8% for non-latex users versus 6.4% for latex users, though this difference wasn’t statistically significant. With consistent, correct use, the gap narrowed but remained: 4.9% for non-latex versus 1.0% for latex.
These numbers don’t mean polyisoprene condoms are unreliable. They still provide meaningful protection against both pregnancy and STIs. But if you don’t have a latex allergy or sensitivity, standard latex condoms offer a slight edge in durability. For people who can’t use latex, polyisoprene is the closest alternative in both feel and function.
Lubricant Rules for SKYN Condoms
SKYN condoms come pre-lubricated, but you can safely add water-based or silicone-based lubricants. Do not use oil-based lubricants, including coconut oil, petroleum jelly, or mineral oil. These degrade polyisoprene the same way they degrade latex, weakening the material and increasing the risk of breakage. This is one area where polyisoprene and latex share the same limitation. If you’ve heard that non-latex condoms are compatible with oil-based lubes, that applies to polyurethane condoms, not polyisoprene.
SKYN vs. Other Non-Latex Options
- Polyisoprene (SKYN): Closest feel to latex, stretchy, compatible with water and silicone lubes only. Good for latex-allergic users who want a similar experience to traditional condoms.
- Polyurethane: Thinner and less elastic than polyisoprene. Conducts heat better, which some people prefer. Compatible with oil-based lubricants. Slightly more prone to slippage because of reduced stretch.
- Lambskin (natural membrane): Made from animal intestine. Effective for pregnancy prevention but does not protect against STIs, because the material has small pores that sperm can’t pass through but viruses can.
For someone with a latex allergy who needs full STI protection, polyisoprene and polyurethane are the two viable choices. SKYN’s polyisoprene tends to be the more popular option because it feels closer to what most people are used to with latex condoms.
