with your bump

Our Band and Brief are made with four-way stretch fabric that gently adapts as your bump grows. Most customers wear the same size from around week 12 through to birth — though some choose to size up in the third trimester if their bump grows quickly.

About the snug fit

The supportwear is designed to sit snugly so the Derma Dot™ pads stay in close contact with the skin. When you take it off at night, you’ll see a light imprint from the pads on your bump — that’s how you know they’re doing their job.

the next-gen brief details

The newly improved sculpting briefs have four-way stretch to support your bump and lower back whilst the Derma Dot™ pads spread the pressure created by stretching skin and block the path of stretch marks as they try to tear downwards. 

The sculpting, tailored support means they don’t dig in, whilst the super soft stretchy fabric provides maximum comfort and flexibility all day long!
Should be worn snuggly against the skin so the pads leave a light imprint on your bump when the briefs are taken off at night. For correct fit please see size guidelines.

Wash at 30°c and air dry.

30-day free returns on UK orders. Preventionwear must be returned unworn, unwashed, and in its original condition with all tags and hygiene liners attached. Full refund policy here.

Reviews

Worked for me!

"I was skeptical, but I wanted to try to minimise stretch marks during pregnancy, so thought I'd give this a go. I wore the briefs most days along with using the morning and night creams. Now six months postpartum I don't have any stretchmarks, which I am thrilled about! I would recommend giving the kit a go."

Rhianna H. (5/5)

You can't have pregnancy without these briefs!

"Love them. I purchased medium size for the start of my pregnancy. Now I'm 5 months I am wearing the large size and it's the best. I have some stretch marks but 100% I would have had more without these due to my south Asian ethnicity. Highly recommend and so glad I found these briefs"

Alexander B. (5/5)

100% recommend

"Used the briefs, gel and cream throughout pregnancy- no stretch marks! Would recommend to all pregnant friends."

Rachel (5/5)

Amazing! Lovely smelling products, feel

"Amazing! Lovely smelling products, feel luxurious on skin, great support, no stretch marks yet at 33 weeks, Brief true ton size, 16 and bought a L and perfect. Bump band bought an XL and too big"

Claire (5/5)

Great invention

"These have been great, I definitely recommend the briefs if your body shape is more curvy - the band kept rising up for me. The cream / gel smells and feels great, the briefs feel supportive - and so far no stretch marks… 2 more months to go!"

Charlotte H. (5/5)

Would definitely recommend

"I have faints stretch marks on thighs and hips from puberty so bought this and Started wearing the knickers at 20 weeks, the day gel is a bit sticky but it helps the pads stick to your tummy. Absolutely love the night cream- it smells really nice and thick but rubs in easily. I am 36 weeks now with no stretch marks at all. I haven't put on a lot of weight during this pregnancy but this is so supportive over my bump and my skin definitely feels stretched and itchy at times when I haven't worn the knickers. Using the creams and the knickers stops these feelings!"

Ceri M. (5/5)

I loved my briefs and

"I loved my briefs and the smell of the gel and cream … I wore later in my pregnancy but successfully avoided any stretch marks. The only issue is with only one pair you are constantly washing and they aren't cheap to buy extra pairs."

Charlotte P. (5/5)

Was skeptical but so pleased it worked.

"Fear of having stretchmarks made me seek this product, many made me doubt that it would work that included family midwife etc however i used this from week 8 up until week of birth and i would def recommend."

Kam S. (5/5)

Worth every penny

"I've used Secret Saviours products for all 3 of my pregnancies and am happily stretch mark free! I am a pear shape and the briefs were excellent - they stayed in place and were super comfy. Worth every penny!"
