Let’s talk lube—the difference between “oh yeah” and “oh no.” The unsung hero of smooth, feel-good play. The ultimate sidekick for solo sessions and partnered romps. 

But here’s the deal: not all personal lubricants are as innocent as they seem. Some are packed with sketchy ingredients that can mess with your vaginal flora, trigger irritation, or even up the risk of a yeast infection (yeah, hard pass).

If your lube is working against you instead of for you, it’s time for a little label reading. 

Nothing should ruin the vibe—not irritation, not dryness, and definitely not harmful chemicals. So, what should you be watching out for? WOO’s got you covered with a red flag list of lube ingredients to avoid, plus two of our all-time faves that keep things wet without the worry.

Why Lube Ingredients Matter

Your skin absorbs everything you put on it, and your intimate areas? Extra sensitive. Using the wrong lube can lead to unwanted side effects like irritation, yeast infections, and even allergic reactions. And let’s not forget: some lube ingredients can break down condoms (please no), making them useless for protection against STIs and pregnancy.

If you’re using lube (which, lowkey, you absolutely should be), you want one that supports your sexual pleasure without compromising your health. Let’s break down the biggest no-go’s hiding in your bottle.

1. Propylene Glycol: The Moisture Stealer

Sounds science-y and harmless, right? Nope. Propylene glycol is commonly found in water-based lubes, but it’s also a skin irritant. While it helps lube stay slick, it can lead to dryness, irritation, and even allergic reactions—which is the exact opposite of what we want from lube.

What to use instead: Look for natural moisturizing ingredients like aloe vera or coconut oil, which provide hydration without irritation.

2. Chlorhexidine Gluconate: The Vaginal Flora Disruptor

Chlorhexidine gluconate is an antiseptic that kills bacteria. That might sound great at first (clean = good, right?), but your vagina has a delicate balance of bacteria and yeast that needs to stay intact. This ingredient can wipe out the good bacteria, leading to bacterial vaginosis (BV) or a yeast infection. No, thank you.

What to use instead: A pH-balanced lube (like our water-based Shag Juice!) will keep things in harmony (and silky smooth, of course).

3. Parabens: The Hormone Disruptors

Parabens are commonly used in personal care products as preservatives, but they’ve been linked to hormonal imbalances and even breast cancer. Research suggests they mimic estrogen, which can mess with your body's natural hormonal rhythms.

What to use instead: Choose paraben-free lubes. Natural oils and organic ingredients are a safer way to keep things sexy without the added risks.

4. Glycerin: The Sneaky Sugar

Glycerin makes lube feel extra slick, but it also feeds yeast, and may increase  the risk of infections (especially if you’re prone to them). Since yeast thrives on sugar, glycerin-based lubes can throw off your vaginal pH and make it a playground for bacteria.

But wait—let’s clear something up:

Not all “glyceryl” ingredients are the same. Polyglyceryin-3, found in our Coconut Love Oil, has a larger molecular structure that’s less likely to penetrate skin or disrupt vaginal flora. It’s a gentle emulsifier, not a sugar—and it doesn’t come with the same risks as traditional glycerin. Translation? You still get that glidey, hydrating feel without inviting yeast to the party.

What to use instead: Look for glycerin-free or polyglycerol-based lubes, especially if you have sensitive skin or a history of yeast infections.

5. Petroleum-Based Ingredients: The Condom Killers

Lubes containing petroleum jelly or mineral oil (yep, the same stuff in Vaseline) don’t play well with latex condoms. They weaken latex, making condoms more likely to break (which is so not on the to-do list). Plus, petroleum-based lubes can trap bacteria, increasing the risk of infections.

What to use instead: If you’re using condoms, stick to water-based or silicone-based lube that’s condom-safe.

6. Artificial Fragrances & Dyes: The Irritation Factory

Fragrances might make your lube smell good, but they can also irritate your skin and throw off your pH balance. Similarly, dyes serve no purpose other than making your lube look fancy, but they can cause allergic reactions and irritation.

What to use instead: If you want to smell and taste good down there, opt for natural scented lubes or flavored lubes made with natural extracts. Coconut Love Oil volunteers as tribute (and tastes like vanilla cupcakes!).

7. Silicone-Based Lubes & Silicone Sex Toys: A Sticky Situation

Silicone-based lubes last forever (great for marathon sessions), but they don’t mix well with silicone sex toys. The ingredients break down the toy’s surface over time, making them more porous and harder to clean.

What to use instead: If you love silicone sex toys, stick to water-based lubes, which is safe for all materials.

Lube Ingredient FAQ’s

Can lube cause yeast infections?

Maybe—but it depends. Many doctors believe that ingredients like glycerin can contribute to the growth of yeast and may increase the risk of yeast infections, especially if you’re already prone to them. Glycerin is a sugar alcohol, and yeast loves sugar—so the connection makes sense. But the science? Still a little fuzzy.

If you have sensitive skin, a tricky vaginal pH, or a history of infections, it might be best to play it safe and stick to glycerin-free options.

What’s the best lube for sex toys?

If you're using silicone sex toys, avoid silicone-based lubes, as they can break down the toy over time. Instead, opt for a water-based lube, which is safe for all toy materials.

How do I know if a lube is safe?

Check the label—but also check the brand. Look out for ingredients like propylene glycol, parabens, petroleum-based oils, artificial fragrances, and chlorhexidine gluconate. 

But let’s be real—you shouldn’t have to be a walking chemistry textbook to shop for lube. That’s why it’s just as important to choose a brand you trust—one that’s committed to making body-safe, pH-friendly products (like, say, WOO 👀). When in doubt, stick with formulas that align with your values and prioritize your pleasure and your health.

Can I use saliva as a lube substitute?

Technically, yes—but it’s not the best idea. Saliva dries out quickly, offers zero lubrication benefits, and can introduce bacteria that might cause infections. Stick with a good lube instead.

Final Thoughts On Ingredients To Avoid In Lube

The right lube balances pleasure, comfort, and sexual wellness. The wrong ingredients can turn a hot moment into an itchy, irritated mess (hard pass), while the right formula keeps things silky, body-safe, and sexier than ever. 

If you want to stay smooth without the sketchy additives, grab a bottle of Coconut Love Oil or our water-base Shag Juice and let the fun begin. Because you—and your bits—deserve the best.
