RFSU - 37°C Lube - 50 ml

RFSU 37°C Lube

Some lubes just add slip. This one adds warmth. RFSU 37°C Lube is a water based lubricant that gently heats to body temperature when it meets your skin, creating a soft, natural warmth that feels less like a product and more like… you. It's a 50 ml bottle of silky-smooth glide designed to reduce friction, add comfort, and make everything flow a little easier.

No sharp heat, no sticky residue. Just a mild, pleasant warmth paired with the kind of slip that stays long enough to matter. Works beautifully for intimacy, solo play, or anytime you want extra moisture and a touch of sensation.

How it feels

The formula is built to react to your body's natural heat, warming gently on contact. It's subtle, cozy, and surprisingly natural. Texture-wise, expect a silken glide that absorbs slowly and doesn't clump or pill. Because it's water-based, it may need a refresh during longer sessions, but a little squeeze brings the slip right back.

Unscented and pH-balanced, it respects sensitive areas without fuss. No overwhelming fragrance, no tacky aftertaste. Just smooth, body-friendly moisture.

Compatibility & Ingredients

This is a water-based lubricant, so it plays nicely with latex condoms and every toy material out there, including silicone. Easy cleanup, too (rinse with water or a damp cloth). The formula is vegan-certified and dermatologically tested, with no animal-derived ingredients.

If you're sensitive to propylene glycol or glycerin, check the full ingredient list first. Those are common in warming lubes, but not everyone's skin agrees with them.

Who it's for

Ideal for couples looking to add gentle warmth to intimacy, or anyone who finds standard lubricants for sensitive skin too neutral or clinical. It's also a solid pick if you want a long lasting lubricant (with occasional top-ups) that doesn't overwhelm with sensation but still delivers something special.

RFSU's profits support sexual health education, so you're backing good work while you shop.

Good to know

Apply a small amount where you want extra glide. Give it a moment to warm up, you'll feel the gentle heat kick in within seconds. Reapply as needed, especially during extended play. The bottle uses 50% recycled plastic, a thoughtful touch from a brand that's been around since the '30s.

Store at room temperature, away from direct sunlight. If irritation occurs, rinse and discontinue use.

Before you play: quick prep

RFSU 37°C Lube is a water-based lubricant that warms up to body temperature on contact—so it feels natural, not chilly. Start with a small amount, let it warm for a moment, then add more if you want extra glide.

Tip: Because it’s water-based, you may want to reapply during longer sessions. That’s normal and part of the “fresh, clean, easy” charm.

Best ways to use it

With condoms

Condom-friendly and designed to reduce friction. Apply a little to the outside of the condom (and/or your body) for smoother comfort.

With toys

Safe with all toy materials, including silicone, glass, metal, and plastic. Add lube directly to the toy or to the body—wherever you want more slip and softness.

For everyday comfort

Many people use it to help with dryness (from stress, hormones, meds, postpartum, menopause—life happens). If irritation appears, rinse with water and stop using it.

Cleaning & hygiene (keep it easy)

This lube rinses away with water. For toys and accessories, you’ll get the best, most worry-free clean by finishing with Mshop Clean:IT for antibacterial cleaning.

Good to know (sensitive bodies)
