Have you been incorrectly taught that your clients cannot hydrate their skin via water intake and diet?

This is a common misconception taught to dermatologists, functional nutritionists, skin therapists and estheticians. If this was part of your training I'm sorry to say that you've been lied to misinformed.  Fortunately, you've landed here and can now begin your exciting journey into the evidence-based science of Skin Hydration Biomechanics to help your clients experience deep and superficial skin hydration

The following screenshots are from a recent 'ask the experts' article about skin hydration. 

Now let's destroy this skin hydration myth with science...

In a study using 34 females drinking 2L of water daily for 30 days superficial and deep skin hydration occurred

Skin Res. Technol. 2015 21(4) 413-8

The main function of Aquaporin 1 is played in the vascular endothelial cells, where it mediates the exchange of water between the blood and dermis to maintain hydration.

Int J Mol Sci. 2022

Drinking more than 2L a day can have a significant impact on skin physiology

Int. J. Cosmetic. Sci. 2007 29(2) 131-8

But it's not all about water

One of the core focuses of this course is on skin-hydrating foods. You'll learn which functional plant foods and phytochemicals are particularly beneficial for skin hydration and how to incorporate them into your clients' diets. And you'll learn about the foods and dietary patterns that can cause or worsen skin dehydration.

If you're not already fascinated with functional skin hydration foods and phytochemicals you soon will be...

Learn the role of osmolytes in skin hydration and which foods they are in

Discover how the phytochemicals in Parsley and Red Grapes regulate water homeostasis in the skin. 

Found out what sorbitol, lecithin and glycerol in the diet have to do with skin hydration

 During my work as a skincare formulator I noticed that so many cosmetic ingredients were foods or food extracts, I realised that the power to beautify, treat and rejuvenate the skin was in diet, nutrition and food...not skincare products
