I've read here and several other blogs that mineral oil, vitamin-E and a few other very inexpensive products are both hydrating and non-comedogenic.
WOuld that make them effective every day go-t moisturizers? That said, what is the benefit of spending anything more than the couple bucks it costs for these products on expensive moisturizer formulas? Even inexpensive ones that are $10-$20 seem expensive compared to the $3 it costs for an absolutely enormous bottle of mineral oil? We know it works, why would we throw our money at anything else? Would I be doing my skin a massive disservice by forgoing my current moisturizer (clinique gel) in favor of using mineral oil long term?
You certainly won't be hurting your skin by using mineral oil but you may be missing out on some of the benefits of a fully formulated product. Here are three examples:
1. Balanced moisture Fully formulated lotions containing water and ingredients that can attract water to your skin like glycerin. You won't get that with just mineral oil.
2. Non-greasy feel Compared to modern lotion formulas which feel nice and soft on the skin mineral oil can leave you feeling a bit, well, oily.
3. Special function ingredients Creams and lotions can deliver sunscreens and retinol which are both important antiaging ingredients that you won't get from just mineral oil.
