If you have very dry skin it means that you do not produce much of your own moisturizer (aka sebum produced in your sebaceous glands in your pores that is commonly termed ‘oil’). Generally man-made moisturizers should only be applied where you do not naturally produce your own skin moisturizer. See the video Moisturizers: Yes? or No?
For dry skin I recommend that at night you use a hyaluronic hydration gel like Tu’el Hy-drate or Hale Dermist M3 HA and then apply a moisturizer on top of the hydration gel. Hyaluronic will hold water in the skin (and thus hydrate the skin) whereas a moisturizer is an emolient layer that makes the skin feel soft and silky. I recommend that you use a light moisturizer lotion like Skin Renu’s lipid based products . There is more information about these at the Online Shop .
Most people do not need very heavy moisturizers if they use a truly gentle (non-stripping) cleanser .
If you have exceptionally dry skin (due to having used Accutane in the past, or you take very drying medical drugs, or you are post-menopause) then a layer of Vaseline on top of the moisturizer will help….
For daytime moisturizers you should use one that is suited to the environment in which you work (cold/hot temperatures) as well as your stress levels as both of these have an impact on the amount of natural moisturizer that you produce in your skin. Rather use a hyaluronic hydration gel and a small amount of moisturizer rather than too much moisturizer. As I have often noted before, I do not believe in combined moisturizer sunscreens…see the video Moisturizers: Yes or No?
