As I was drafting my allergy article, I just realized that there are so many hypoallergenic soaps that newborns or people with sensitive skin can use. And these soaps aren't necessarily that expensive or hard to find. Dove White, for example, can be found in grocery shelves as well as drug stores. Use of these soaps can also be one of the best acne treatments there is since they won't strip your skin of its natural oils. Because they are gentle too, you can use them more times in the day.
Check out your local drug store for trusted and handy brands. Check out message boards or referrals and organic, local products. There are so many to choose from. The gentler the scent, the gentler the soap is sure to be. And yes, ask moms what they use for their newborns. After all, even if our faces (and skin) do so much for us during the day, it still really needs utmost care like the one we give to wee babes.
