Lena Dunham bared all on her Instagram story on Wednesday while wearing a bikini.
Dunham, who has never shied away from baring her body onscreen or off, posted photos of herself wearing a bikini from Target proudly displaying her scaring from endometriosis.
“When the Target swimsuit does a bitch right, Endo scars & all,” she wrote.
Endometriosis is a disorder that causes the tissue lining the uterus to grow outside it, according to the Mayo Clinic.
The illness can be painful, causing excessive bleeding, fatigue, bloating and possible infertility.

Dunham posted a picture on Instagram on Tuesday, saying she’d “dealt with my share of Internet trolls” and was happy about the new comment filter on Instagram that allows hate comments to be blocked.
“As a public person I know I’m taking on a certain amount of hate and I armor myself (though that doesn’t mean I don’t go totally effing nuts when I see some of my heroes getting attacked online for things like their race or sexuality.)” she wrote. “But I can’t help but wonder how people without the same resources have learned to cope.”
The star stripped down with friend and co-star Jemima Kirke in August as part of a new body positive, un-retouched underwear campaign for Lonely lingerie.
