As a person with dry skin and with a certain age, I am always on the look for a serum that helps my skin. I have heard about the T.E.W.L. serum for many years as it has excellent reviews. I always hesitated to try for its price as in my opinion is extremely expensive for a skincare product. But I decided to take the hit and try it. Here is my experience

My Review
My review: I had high expectations of the product for 3 reasons: for the company, the reviews, and the price. But unfortunately, did not meet expectations and my skin looked and felt dry.
