Again - I am a big fan of your blog/podcast.
I am trying my best to use products that would really benefit my skin and this benefit would be based on science so I read your blog and others and try to use the best judgement. However sometimes I get sort of confused as it seems that different cosmetic scientists have different opinions.
I thought that since this is science it should be objective so how come these different statements?
For example alcohol denat. I am so confused about it. As I understand there are differences in opinions if it is ok for skin or it could encourage aging of skin. I know that after all a user should decide if it is okay for her but what if after 10 years of using products with alcohol denat I get more aged skin than using alcohol free products? Is that possible?
Please shed some light on this matter.
