Underarm Waxing: 30% Risk in 2026

Think about this: around 30% of adults in the US are on a daily prescription medication. That’s a huge number, and it directly impacts what we can and can’t do in the treatment room, especially with something like underarm waxing. You can’t just use a one-size-fits-all approach when so many people are dealing with medications and skin conditions that change how their skin reacts.

The Impact of Retinoids: A 200% Increase in Skin Sensitivity

People using retinoids (topical or oral stuff like tretinoin, isotretinoin, or adapalene) see their skin sensitivity shoot up by as much as 200%, and that’s a number we see backed up in dermatology clinics all the time. This goes way beyond a little redness. We’re talking about seriously compromised skin integrity. Retinoids speed up cell turnover, which thins out the top layer of skin and makes it incredibly fragile, so it’s prone to tearing, lifting, or getting severely irritated when waxed. I’ve personally seen cases where the gentlest wax application on retinoid-treated skin has lifted off a layer of skin, causing a long healing process and hyperpigmentation. Everyone talks about not waxing your face on retinoids, but they forget the underarms, an area with delicate skin and constant friction that’s just as vulnerable, maybe even more so. With all the lymph nodes and sweat glands right there, any irritation can escalate quickly. A study in the Journal of the American Academy of Dermatology is very clear: if you’ve been on systemic retinoids, you must wait at least six months after stopping before you wax. That’s a hard rule, a critical safety measure.

Anticoagulants and Bruising Risk: A 50% Higher Incidence

If you’re on anticoagulant medications, which are just blood thinners like warfarin, heparin, or other direct oral anticoagulants, your risk of bruising and bleeding from a wax is up to 50% higher. It’s simple: these meds stop your blood from clotting efficiently, so the minor trauma of ripping hair out can cause major bleeding under the skin. You end up with big, ugly bruises that are painful and take forever to heal, especially in a high-movement area like the underarm. A report by the American Society of Hematology goes into the different types of these drugs which just reinforces why we have to be so careful. So many clients don’t think to mention their heart medication or DVT prevention pills during their intake, but I have to know this stuff. The underarm is packed with superficial blood vessels, which makes it a high-risk zone. As professionals, we have to ask about a client’s entire medical history, because it’s all connected to the service, not just the parts that seem obviously related to hair removal.

Steroid Use and Skin Thinning: A 40% Reduction in Epidermal Thickness

Long-term use of corticosteroids, whether they’re creams or pills for things like eczema or asthma, can thin out your epidermis by a shocking 40%. Thinner skin is fragile skin, meaning it tears easily and can’t handle the pull from waxing. The skin loses its elasticity and basically can’t bounce back from the adhesion of the wax, a condition discussed in a review in Dermatology and Therapy about the side effects of corticosteroids. So what does this mean for an underarm wax? It means if a client used a steroid cream for a patch of dermatitis under their arm, the skin might look fine now, but its underlying structure is weak. Trying to wax that area is asking for skin lifting, nasty redness that won’t go away, and even infection. The point is to understand what your body is going through and choose an alternative or just wait for your skin to regain its strength.

Antibiotic Sensitivity: A 25% Increase in Photosensitivity and Irritation

Not every antibiotic is a problem, but some, especially tetracyclines and fluoroquinolones, can make your skin more sensitive to irritation by up to 25%. This includes photosensitivity. This increased reactivity means something as simple as a wax can cause a massive inflammatory response, we’re talking intense redness, itching, or even a rash where you normally wouldn’t get one. The FDA has even put out warnings about photosensitivity with some of these drugs, and that sensitivity applies to other skin stressors, not just sunlight. And while your underarms aren’t getting a tan, the whole system is on high alert. Clients on antibiotics for a sinus infection have no idea it could affect their wax. This is exactly why a thorough intake form and a real conversation are so important. I make it a point to ask about *all* medications, not just skin creams, because the systemic effects are no joke.

Challenging Conventional Wisdom: The “Just Be Gentle” Fallacy

I hear it all the time: for clients on meds or with skin issues, just “be more gentle.” That’s not just wrong, it’s a dangerous oversimplification. No amount of gentle technique is going to overcome the biological reality of skin that’s been compromised. The idea that a soft touch can magically fix a 200% increase in fragility from retinoids or a 40% thinner epidermis from steroids is absurd. The skin’s barrier is either intact and ready, or it isn’t. Period. In these cases, the problem is the skin’s biological capacity, not the esthetician’s technique. I’ve seen it too many times. Trying to wax compromised skin, no matter how carefully, ends badly. Take a client with eczema. Even if it isn’t flaring under their arms, their skin barrier is already impaired. Waxing that skin can easily trigger a flare-up, let bacteria in, and make the whole situation worse. Sometimes the only safe choices are other hair removal methods or just waiting until the skin is strong enough again.

Knowing how medications and skin conditions mix with underarm waxing is the most important part of the job for us and for you. The goal is always safe hair removal with good results, and sometimes that just means we have to wait or pick a different method. A good conversation and proper assessment are what prevent pain and skin damage. And if you do end up with flawed waxing results, you need to figure out the real reason why.
