How Much Hydration Does Skin Really Need?

Hydration is more complex than you think.   In general, plain water is what you need to drink for hydration.   It’s better than soft drinks, including “diet,” with too much sugar and too many chemicals.   Fruit juice is better but only if it’s really fresh.  And too much coffee can dehydrate you.  

6-8 glasses of water a day are recommended.  

Skin is an organ!

 

It’s true that the very outer layer of the skin doesn’t get very hydrated, but that’s because it’s getting ready to shed.  It is also true that sleep is extremely important for hydration.  During sleep, the water in our bodies re-equilibrates, and the fluid that collects in our legs during the day, flows back when we lie down, to our faces.   Think reversing gravity!

 

Healthy oils like olive oil, avocado oil, nut oil, etc don’t “hydrate” skin but they do supply the oils that are building blocks for the fats naturally present in skin, and help keep it healthy and pliable. They make skin look more hydrated.

One of the best investments in your skin is your daily skincare. Why? Because you can prevent many problems with blotchy skin color, lack of glow, texture, some types of acne, and fine lines with good skincare products. You can also correct some of these problems with effective skincare products. Great skincare is often more expensive because quality ingredients are expensive. Some companies spend on research/development which benefits all of us and adds to the cost. Are they worth it? In general - yes! I have handpicked some of what I consider to be the best skin care products, and offer them for sale on SkinTour's shop. This is based on my team and I's testing and research at our clinic. Many of the products are in my own regimen. What could be better than using skin care products a dermatologist uses?!
