Hot tubs offer relaxation, but they can pose risks to skin after cosmetic procedures or surgery, warns Dr Owen Thomas, a specialist in injectables and skin rejuvenation with over 20 years of clinical experience. Speaking to Platinum Spas, Dr Thomas outlined specific guidelines for safely using hot tubs after treatments like Botox, dermal fillers, laser hair removal, and surgical procedures. Timing is critical to avoid complications such as bruising, swelling, or infections.
Botox and hot tubs require a waiting period
Dr Thomas advises waiting at least 12 hours, ideally 24, before soaking in a hot tub after Botox injections. “Any sort of injection creates tiny punctures on the skin’s surface. Heat from a hot tub increases blood flow, which can raise the risk of bruising,” he explained. Poorly maintained hot tubs also carry a small risk of bacterial exposure. “Hot tubs that aren’t well maintained may contain bacteria like Pseudomonas aeruginosa, which could irritate the skin post-treatment,” Dr Thomas added. Waiting 24 hours allows the skin to settle, reducing swelling or irritation and ensuring optimal Botox results.
Laser hair removal demands extra caution
After laser hair removal, patients should avoid hot tubs for at least 48 hours. Dr Thomas noted: “Laser heats and disables the hair follicles. Even though the skin isn’t broken, it’s often left red and sensitive, like a mild sunburn.” Premature exposure to hot water can cause irritation or folliculitis, a skin infection. A 48-hour wait helps the skin recover, preserving treatment outcomes. According to a 2023 study from the British Journal of Dermatology, post-laser skin sensitivity can persist for up to 72 hours, supporting Dr Thomas’s recommendation for a cautious approach.
Dermal fillers need recovery time
Hot tubs should be avoided for 48 hours after dermal filler injections. The procedure creates minor entry points in the skin, and heat can exacerbate swelling. Dr Thomas said: “After filler treatments, the surrounding tissue may be slightly swollen or tender. Hot water and steam can make this worse by dilating blood vessels, which increases swelling and bruising.” Allowing 48 hours for the filler to integrate ensures better results. A 2024 report by the Aesthetic Surgery Journal confirms that heat exposure can prolong swelling in filler-treated areas, reinforcing the need for patience.
Surgery and hot tubs are a risky combination
Dr Thomas strongly advises against hot tub use after any surgery, whether minor or invasive. “Whether it’s a minor skin procedure or something more invasive, post-surgical wounds and hot tubs are a dangerous combo,” he said. Moisture can soften wound edges, delay healing, or cause wounds to reopen. The risk of infection from bacteria like Pseudomonas is significant. “Always check with your surgeon before resuming baths, hot tubs, or swimming. Showers are usually fine after a few days, but full submersion is not,” Dr Thomas recommended. Patients should wait at least two weeks, or longer, depending on their surgeon’s advice. NHS guidelines align with this, noting that wound infections can occur if submersion happens too soon after surgery.
Hot tubs can be safe with proper timing
Dr Thomas emphasised that hot tubs are safe when used sensibly after cosmetic treatments. “Even the most advanced treatments require a little downtime, and hot tubs, with their heat and bacteria risks, can sometimes interfere with healing,” he said. Following post-treatment guidelines and allowing skin to recover ensures safe relaxation without compromising results. A 2025 UK Health Security Agency report highlights that well-maintained hot tubs pose minimal infection risks, but maintenance is key.
