It’s expensive for a reason, this stuff works! Even better than the steroids
Scent: Fragrance Free, Size: 2 Pack - 3.5 Ounce & 8 Ounce
It’s expensive for a reason! This stuff works, my 4 mo old has been struggling with eczema for 2 months now and we have been to the ER twice due to infections, I’ve taken everything out of my diet since he’s breastfeeding, we’ve tried every other cream and routine out there. Up until just a few days ago when we ordered Tubby Todd’s his cheeks were constantly raw and weeping. After just 3 days of use with Tubby Todd’s he is finally getting some reprieve and we are finally getting SLEEP (before we would have to hold his hands down manually all night so he wouldn’t itch himself raw) this cream is even better than the steroids, you won’t regret purchasing even at the high price point.

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.
