Bridgerton actor Yerin Ha reveals she developed folliculitis after filming a bathtub scene. Here’s what hot tub rash is and how to prevent it.

An intimate scene in Bridgerton 4 led to folliculitis for Yerin Ha.

Lavish sets, choreographed intimacy and cinematic romance often hide the physical toll actors endure behind the scenes. Even on productions celebrated for their sensitivity and polish, the realities of long shoot hours and technical demands can quietly affect health. A recent revelation from Bridgerton season four brings this into sharp focus – spotlighting how prolonged exposure to water, products and friction can trigger unexpected skin conditions.

The second part of Bridgerton Season 4, released on Netflix on February 26, features a visually arresting bathtub intimacy scene between Sophie and Benedict. While the moment translated as seamless on screen, the experience proved far more challenging for actor Yerin Ha, who plays Sophie opposite Luke Thompson.

Speaking on the February 25 episode of the Capital Breakfast, Yerin revealed she developed folliculitis following the shoot. The scene reportedly took six to seven hours to film, during which both actors remained submerged in bathwater for extended periods.

Ahead of filming, she followed preparation protocols, applying baby powder to help keep her skin dry and wearing taped intimacy garments. The aftermath, however, was swift and uncomfortable.

“And then basically the next day after the bathtub, I got hives all over my body and got folliculitis and needed steroid cream!” She added, “But I blame myself, because I think it was a combination of baby powder and the bath water.”

What Is Folliculitis?

Folliculitis is a common skin condition caused by inflammation of hair follicles, most often due to bacterial infection. It typically appears as clusters of itchy, tender, pimple-like bumps around hair follicles. In mild cases, folliculitis may clear on its own within a few days. More severe or recurring infections, however, may require medical treatment and can lead to scarring or permanent hair loss if left untreated.

Based on Ha’s symptoms and water exposure, the condition is most consistent with Pseudomonas folliculitis — often referred to as ‘hot tub rash.’

Why Hot Water Can Trigger ‘Hot Tub Rash’

Pseudomonas folliculitis is caused by bacteria that thrive in warm, inadequately treated water. Hot tubs, heated pools and water features are common sources, especially when chlorine and pH levels are not properly balanced.

Symptoms typically appear one to two days after exposure and tend to worsen in areas where wet fabric traps moisture against the skin – such as under swimwear or taped garments.

How To Reduce The Risk?

• Wash skin regularly with clean towels and washcloths
• Avoid prolonged friction or pressure on the skin
• Change out of wet clothing promptly
• Shave carefully using clean tools
• Use only well-maintained hot tubs or heated pools
• Shower with soap immediately after water exposure
