What Lubricant to Use for Silicone Toys?

Lube makes a great addition to your sex life. It’s soft, slippery, and enhances sensation—helping everything feel smoother, more comfortable, and more enjoyable. Whether you're exploring solo or partnered play, the right lube can make all the difference. So what’s not to like?

With so many different types of lubricants available—water-based, silicone-based, oil-based—it’s important to know which one works best for different situations. That includes choosing the right lube when using sex toys, especially those made of silicone. Using the wrong combination could lead to damage or discomfort.

Read on to learn more about silicone sex toys and whether silicone lube is a safe choice to use with them.

What Are Sex Toys Made Of?

Many sex toys are made of silicone, a type of rubber made from silica, a compound found in sand. Silicone can come in a few different formats. Medical-grade silicone is made according to rigorous standards set forth by the FDA.¹ It’s used to make medical devices and menstrual cups, as well as butt plugs and other sex toys designed to be worn inside your body. 

Most other sex toys are made out of a silicone known as body-safe silicone. Though this type of silicone doesn’t go under quite as rigorous of testing, it’s still considered to be generally safe for direct contact with your body. Body-safe silicone is hypoallergenic and won’t cause irritation. 

Is Silicone Lube Safe?

Silicone lube is a safe type of lube to use during sex. It’s compatible with latex condoms and less likely to cause irritation or vaginal inflammation, which can sometimes occur with other formulas. Silicone lube is known for its silky-smooth texture and long-lasting glide, making it especially helpful during longer sessions or for shower and water play, since it won’t wash away easily. Because it isn’t absorbed by the body, it stays slick longer and usually doesn’t need to be reapplied as often.

However, while silicone lube has many advantages, it’s not safe to use with silicone sex toys. The silicone molecules in the lube can bond with the material of your toy, breaking it down over time and leaving behind a sticky or degraded surface. This can shorten the life of your toy and potentially create safety concerns. If you're using silicone toys, it's best to stick with a high-quality water-based lubricant to keep both your body and your toys in great shape.

Silicone Lube Myths

Have you heard some of the common myths about silicone lube? From concerns about safety to confusion around when and how to use it, there’s a lot of misinformation out there. Read on as we debunk these misconceptions and set the record straight.

Silicone Lube Irritates Skin

Silicone lube is actually one of the safest types of lubricants available. Silicone is a naturally hypoallergenic substance, meaning it won’t cause irritation or allergic reaction in most people. 

If you’re worried you may get an allergic reaction from silicone lube, we recommend applying a small amount to a less-sensitive area of your body and waiting 24 hours to monitor for reaction. 

Only Old People Need to Use Silicone Lube

While it is true that menopause can bring on vaginal dryness, it’s not the only reason you may want to use lube. Many things can cause vaginal dryness, including medications, medical conditions, and hormone fluctuations. 

On top of that, lube isn’t only for people with vaginal dryness. Even those who have no issue with their natural lubrication can benefit from lube. At the end of the day, wetter sex feels better—and silicone lube is a great way to achieve it. 

Silicone Lube Is Only for Penetrative Sex

Silicone lube is a great addition to penetrative sex, but that’s not the only thing it’s good for. Silicone lube can increase pleasure for any kind of sexual touching: fingering, handjobs, and other acts. Just be sure not to use silicone lube with your silicone sex toys, as it can make them unsafe. 

Can You Use Silicone Lube with Toys?

As wonderful as silicone lube is, you can’t use silicone lube with silicone toys. The silicone in silicone lube can cause a process known as plasticization, a chemical reaction that makes the silicone more flexible and pliable. Additionally, some silicone lubes contain oils that can soften silicone and make it expand. If you put silicone lube on toys, it will degrade them and make them porous.³ A porous sex toy is the perfect breeding ground for harmful bacteria. 

What Is the Best Lube for Silicone Sex Toys?

Like silicone-based lubes, oil-based lubes are also unsafe to use with sex toys. Oils can cause silicone toys to expand and become softer, again creating a bacteria breeding ground.³ 

For the safest possible outcome, it’s best to use water-based lube with silicone sex toys. Water-based formulas are gentle, non-reactive, and won’t damage the surface of your toys the way silicone-based lubes can.

Always check your lube’s packaging or product description to confirm that it’s safe for use with toys, especially if they’re made of silicone. Taking this extra step helps protect both your body and your favorite pleasure products.

Conclusion

Lube is a great way to enhance your sex life, but it’s important to know which type of lube to use for what occasion. While silicone lubricants are safe for many types of sex, they can’t be used with silicone sex toys.
