It would be very useful to have a dermatology episode (I'm not sure if that would connect nicely to the 'sunscreen' discussion, but it could dovetail nicely). It could cover typical skin diseases/issues and causes/treatments - and whether there are 'internal' ways to provide relief (how many skin issues are caused by microbiome or diet imbalance). Along with the sunscreen issue, are there general additives and ingredients that are red flags to avoid when buying skin products. Also, is there science behind all the 'serums' and products out claiming to even skin blemishes and tones (are they actually healing the skin or just covering things up)? Are there possible negative consequences to using them (similar to mouthwash...is it a temporary fix that ultimately isn't a positive)?
