Affordable
Model: Hydrocolloid, Size: 102 Count (Pack of 1)
These patches are a good value for the price and work as expected. They stick pretty well and are relatively discreet on the skin. They don’t perform miracles overnight, but they do help keep the area clean and protected. I usually notice improvement after a couple of days. My only real complaint is that I wish the small size was just a bit larger. Overall, solid and affordable option.

INVISIBLE
Model: Hydrocolloid, Size: 102 Count (Pack of 1), Model: Hydrocolloid, Size: 102 Count (Pack of 1)
These are basically invisible so you can wear them during the day! And they actually work! Incredibly thin so I use tweezers to apply them. Have been so great for my hormonal acne during pregnancy. Highly recommend!!

Adheres well, nearly invisible
Model: Hydrocolloid, Size: 102 Count (Pack of 1)
I enjoy how clear, invisible and thin this is on. It compares to the one I bought in Japan that I liked. It’s fairly effective as well and adheres on the skin well. I always try to remove excess product on the surface of the area though. I like the protective film and easy peel sheets and that there’s two sizes available in packet!

Waterproof?
Model: Hydrocolloid, Size: 102 Count (Pack of 1)
It is nice that there are a lot included, but it is disappointing that the waterproof function is weak, so they come off easily when they get wet. I wish the adhesive were stronger

Fun
Color: Green
Was fun to play tug of war with my dog till she completely destroyed it by taking out all the stuffing, squeakers, and ripped the limbs off. Soft before dog droll and weather stiffened it. She liked to leave it outside for some odd reason like her other toys.
