A., KUDOS to you on wanting to take care of your good skin now, rather than trying to "fix" any future problems down the road!! Most expensive also doesn't equate to the "best" or most beneficial. (If you're interested, I've got some great pictures which compare some of the "best" anti-aging creams and actually show clinical evidence of oxidation.)
I have used for years and highly recommend the ENFUSELLE skin care line by Shaklee. This line is protected by 8 patents, is clinically formulated, pH balanced, non-comedogenic, botanically based, hypoallergenic, dermatologists tested, never tested on animals, and contains no animal-derived ingredients, free of occlusive oils, soap, and dyes.
Shaklee is the #1 natural nutrition company in the US and is recognized as pioneers in the development of nutritional supplementation for almost 50 yrs. Because Shaklee takes a new approach to skin nutrition, ENFUSELLE never includes harsh ingredients that others do to achieve short-term results but that may not lead to a lifetime of beautiful, healthy skin. Shaklee invested more than $1 MILLION in R&D and clinical studies on the products that make up the ENFUSELLE SKIN CARE SYSTEM. Please let me know if you're interested in learning more. You can either reply or contact me at ____@____.com the way, at my 20-yr HS Reunion in FL, two of my male classmates pulled me aside and asked me what my "secret" was for looking soooo much younger than the rest of the class - LOL!! I "shared" that they'd never believe me in a million years ... they waited w/ bated breath ... botox/surgery? Neither - my Shaklee vitamins and ENFUSELLE skin care! Of course they didn't believe me. But, it's true! I'm turning 45 in 2 wks and STILL loving it!! Been using Shaklee 16 yrs.
