Your Skin is the most important part of your body to maintain. You can go without doing your hair ( though it's not always pretty) or cutting your nails or trimming your eye brows but your skin is so important. I had some acne issues As a teen, but don't we all, so most of what I use is for sensitive skin and oil free.
I use purpose soap to wash my face both day and night. For face cream I use CeraVe which has both moisturizer and sunscreen, which is very nice to have because you don't have to think about it.
For make up I go pretty light and natural but do use the essentials:
Concealer from elf
Powder from neutrogena.
I'll also generally put on some mascara (from almay) and maybe some white eye liner but, that's it
