yeah,,
I just saw the picture and I noticed that the dermis label were put in the wrong place..
It should be put in the dense irregular connective tissue bellow the basal layer (stratum germinativum of epidermis)..

No, they really shouldn’t reduce moisturization but it depends on how much you put in and what kind of moisturizer you are using.

Do you know if ingredients to give a “dry fisnish” for the formula, like silica, Nylon-12 etc. will reduce the moisturizer efficacy?

Your diagram is wrong. The dermis is below the basal cell layer.

Thank you for your complements Jennifer! A book titled Antiaging: Physiology to Formulation is a good resource available from Allured Publishing, it is a bit pricey but worth it because it compiles a lot of information that you would have find in individual pieces elsewhere. -Kelly

Thanks so much Kelly for that information, as alot of companies say how bad mineral oil is. Very interesting information about Hylauronic Acid. I think this site is brilliant – I am so glad I found it! If you have one book to recommend to me about the latest skin care ingredients i.e. peptides etc, is there any particular ones you would recommend?

Hi Jennifer,
Thanks for your questions! Mineral oil is a cost-effective occlusive agent. However, there is widespread belief that mineral oil is comedogenic despite a good deal of data to the contrary (see article by DiNardo in Journal of Cosmetic Dermatology, 2005). There also exists some controversy regarding the fact that mineral oil is derived from petroleum, but it is a by-product of the distillation process and is an example of the utilization of a potential waste stream. Hyaluronic acid has powerful water binding capabilities within the skin as it is considered part of the skin’s own natural moisturizing factor (NMF). It is a very high molecular weight polymer which, I believe, would limit effectiveness in topical application because the molecule is just too big to penetrate the stratum corneum.

What do you think of mineral oil used in moisturisers and Hylauronic Acid is this a good humectant?
