So called ‘DR’ brands have been around for a while now. The initial sell of a DR brand was that because a real doctor had a hand in the formulation (maybe), then somehow it must be better. 
Initially, DR brands were totally a buzz in beauty; a new concept in constructing a skincare product based on proven knowledge and endless experience of skin and skin issues. But, wait. Perhaps it is more that if there is DR in the product range title, consumers might think that somehow it is more potent, more clever and more likely to be ‘prescription strength’ than those without. 
Of course, none of the above is true, doctor or not, they still have to adhere to the same set of formulation rules as everyone else. And anyway, there is a way difference between a cosmetic surgeon and a plastic surgeon or even a dermatologist; being wieldy with a needle full of Botox doesn’t mean that you are a medical expert in skin. Not at all. 
In my view, DR brands are clever, clever marketing (there are a couple of notable exceptions here, one of them being Dr Darren McKeown who doesn’t go the ‘hype’ route) that are using their white coats to further their chances of a mink coat. 
Personally, my trust lies in the jobbing beauty therapists who work with skin every single day. They touch it, manipulate it and observe first-hand on real women what products can and cannot do. If I’m taking advice, it’s from them and not a product that says DR on it.
The DR brand days are on a trip to the ER as consumers realise that just because there is a medical implication on the packaging it doesn’t mean you will look any younger than if you used an alternative. The proof is in the buying, and the re-buying.. we might be fooled once, but not twice, it appears.
