A solid option for managing eczema flare-ups.
Scent: Fragrance Free, Size: 2 Pack - 8 Ounce
Tubby Todd Eczema Ointment is a thick, soothing balm that really helps calm irritated skin. It’s gentle enough for sensitive skin and doesn’t have a strong scent. The texture is a bit heavy, so it takes a little work to rub in, but it stays on well and gives noticeable relief.

Miracle Cream
Scent: Fragrance Free, Size: 2 Pack - 3.5 Ounce & 8 Ounce
This cream has been nothing short of a miracle. Within 24 hours, my infant’s dry, itchy eczema improved dramatically, and their skin became noticeably softer and smoother. I was amazed at how quickly it worked. This is an absolute must-have for new mothers dealing with infant eczema and sensitive skin.

good for my sons severe eczema
Scent: Fragrance Free, Size: 2 Pack - 3.5 Ounce & 8 Ounce
i was skeptical to purchase because of the price, i didn’t want to spend that much on a product that potentially wouldn’t work. my son has severe eczema so we’ve tried loads of products including prescribed steroid/non steroid creams. Tubby Todd is the most hydrating of them all. don’t get me wrong, his skin wasn’t healed over night & his eczema isn’t “gone” but after a couple weeks of use his skin is healing & he is having less breakouts. i am so glad i gave Tubby Todd a chance.

Great cream, not so great price
Scent: Fragrance Free, Size: 2 Pack - 3.5 Ounce & 8 Ounce
My one year old has recently started to have eczema in these warmer months and I had heard good things about this ointment so I wanted to give it a try. I grew up with eczema and still have ongoing issues with it and didn’t want her to have to go through the same thing. I also wanted to avoid steroid creams if at all possible so I went straight for “the big guns” and purchased this thinking “oh it has to be the holy grail for this price”. Don’t get me wrong it is a decent eczema cream, but not for the price. You can find much cheaper creams that have the same results. I used this religiously with my daughter and it still did not clear up her eczema. Took her to her pediatrician and ultimately had to use a short term low dose topical steroid that cleared it right up. As far as daily maintenance use I will opt for a less expensive version next time.
