Pre-Portioned Sachets That Calm Itch and Hydrate
Size: 1.47 Ounce (Pack of 1)
These individual sachets make it incredibly easy to prepare a soothing oatmeal bath when your skin is dealing with itching, dryness, or reactivity. I recently had an allergic reaction that left me with intensely itchy hives across my body, and I was willing to try anything that might help. I picked this up because it was reasonably priced, and it ended up being a great decision.
The powder sprinkles smoothly into running bath water and begins to work quickly to calm the skin. Even though it is a powder, it forms only minimal clumps, and any that do appear are easy to break apart with your fingers. My skin felt noticeably more hydrated and far less irritated after soaking, and I was pleasantly surprised that it didn’t leave any residue behind in the tub.
The pre-portioned sachets make the whole process simple and mess-free, which is especially helpful when you’re already uncomfortable. I’ll definitely be keeping these on hand for times when my skin needs extra TLC.

I use these for both myself and my 18 month old when we have eczema flares. Simply pour a pack in a bath and soak. It helps with irritation and itching! Leaves skin feeling soft and moisturized!
