Sensitive skin - Dinah

Last night, I brought the girls to Junction 8 pharmcy to racky moisturizer and body wash for Dinah persistence skin problem.
We went to Guardian searching high and low for the brand Eucerin and Cetaphil but couldn't find. So I thought maybe the guardian too small never sell.
Fruitlessly, we went to NTUC to buy superglue, to repair the strollers. I ended up buying apple cider vinegar, which I learn is good for hair. I intend to experiment. It's good to use less chemical on my hair.
Unwilling to give up, I decided to try again and this round I asked the sale assistant. I just don't believe Guardian doesn't sell.
Finally we found it, and I bought DermaVeen lotion and Cetaphil body wash. I actually wanted to buy Lavender essential oil but too expensive, I dropped the idea.
Dinah seems excited and she wants to try the lotion straight off. Hopefully the lotion help, meanwhile I might wants to mix Cetaphil and Johnson body wash. Concurrently use them, as Cetaphil too costly for such a size, but worried too drying for Dinah's delicate skin.
Perhaps I could add some oilve oil to Johnson body wash so it won't be too drying for her. Who knows if it's suitable for her, then I will do without Cetaphil. Monitor and decide approach....
