Again, what does that mean? A 'science degree'...it could be computer science, palaentology, botany....anything. Unless it's in dermatology, she has no more authority to speak than Hirons (or you or I). It's not about the level of the qualification or intellectual snobbery, but if your qualifications are not in that field, you are not qualified in that field. Either you have credentials, or you don't.I think she has a science degree from what I remember, I watched her couple of her videos and she mentioned it in one and thats why she likes looking into ingredients and what they do, efficacies, research, etc
Making out skincare is complex, there is arcane specialist knowledge that is required or that these women know anything more than any of us is rubbish, and totally disrespectful of those who actually bothered to get proper qualifications.
