A Lovely Addition To My Routine
The skin beneath my breasts needs a little extra care, especially in summer. I like how easily this cream applies after a shower. It feels light on my skin and absorbs well before I get dressed.

Gentle Care Where I Need It
I’m particular about the products I use around my bikini line. This cream has a smooth texture and feels comfortable on the external skin. A small amount is easy to apply without leaving everything feeling greasy.

Under Arms
More Comfortable Every Day
My underarms often feel uncomfortable after a long, warm day. This cream feels gentle, spreads easily, and doesn’t leave a sticky finish. It has been a lovely addition to my daily skincare routine.

“I’ve Tried Powders And Creams. What Makes This One Different?”
Most of what’s on the shelf was designed for diaper rash, not for adult skin folds that stay warm, damp and rubbing together from morning to night.
Fold rash has three causes at once: yeast, moisture and friction. Most products only deal with one of them.
Baby Diaper Cream
Thick, greasy, sits on top. Made for babies, not adult folds.
Baby Powder / Cornstarch
Dries you out for an hour. Does nothing about yeast.
Antifungal Powder
Hits the yeast, but leaves skin burning and raw.
Steroid Creams
Calms it for a day, then it comes right back.
Antiperspirant
Blocks sweat for a while. Stings and irritates folds.
Your skin fold irritation may involve more than moisture. Heat and friction can play a part too, which is why simply soaking up dampness may not address every source of discomfort.
That’s the idea behind the DERMELYN skincare concept: thoughtful care for often overlooked skin folds, with everyday comfort at the heart of the routine.

What Our Customers Are Saying
“I was tired of creams that left me feeling sticky under my bra. What I like about DERMELYN is that it spreads easily and dries down instead of sitting on my skin. Getting dressed afterward feels much more comfortable.”
Under Breast
“The powder-like finish is what won me over. I wanted something for the fold under my belly that wouldn’t leave a thick, greasy layer. This fits into my morning routine without making a mess of my clothes.”
Abdominal Fold
“Honestly, I nearly passed on another cream. I already had a bathroom drawer full of them. I appreciate that this one doesn’t have a strong perfume or that heavy ointment feel. Simple to apply, and pleasant to wear.”
Under Breast
“I bought this for my inner thighs because I hate that tacky feeling when my skin rubs together. The texture surprised me. Creamy when you apply it, then soft and dry once it settles. That’s the part I really like.”
Inner Thighs
“No strong smell, no powder scattered across the bathroom, and no greasy hands afterward. Those might sound like small things, but they make a difference when you’re using something regularly. The tube is handy to take along, too.”
Underarms
“Skin-fold care isn’t exactly something I talk about over coffee, but finding a texture I’m comfortable with matters. I like that DERMELYN feels light rather than heavy. I give it time to dry, get dressed, and get on with my morning.”
