Why is there BHT in it?

Yes, Butylated hydroxytoluene (BHT) is a listed ingredient. On the EWG Skin Deep database BHT is rated a 6 (1-10 scale). We carry other lanolin creams that are similar but don't contain BHT.

Does it have collagen?

The list of contents is as follows: water, glycerin, stearic acid, cetyl alcohol. paraffinum liquidum, cetearyl alcohol. triethanolamine, keratin and hydrolysed keratin, phenoxyethanol, PEG-30 lanolin, lanolin, disodium EDTA, fragrance, ethylhexylglycerin. There is no mention of "collagen." I really like this hand cream.

Can I use on exema rash I need fragrance free!!

Hi Lu. This was developed for eczema 40 years ago. If the eczema is open, I would avoid using right on it. Any open wound could sting at first. I’d apply our lanolin oil on the open areas and this cream around the patch. By next day you should be able to use cream all over. This would depend upon the severety of the rash. Of course you should always consult with your physician if you feel necessary. Hope this helps and if you have any questions feel free to reach out.
