As a Skin Care Specialist, you are up on the latest spa services and trends but do you have a good, working knowledge of ingredients used in your spa products?

Linda Walker has been designing professional skin care products for 25 years. That expertise has been funneled directly into The Skin Care Ingredients Handbook Revised & Expanded Edition, which, in addition to retaining the insight of the first edition, now contains even more of what the working skin care professional needs.

This handbook will help you answer ingredient and product questions from your well-educated, savvy clients and help you sell spa products based on individual needs. A little education goes a long way in boosting your confidence and clinching that extra sale.

The symbols next to each ingredient can easily be matched with the symbols on the bottom of the page which will help in categorizing the ingredient for acne, anti-aging… It's a clever, condensed way for you to find what you need in a hurry.

If you are looking for a current, reliable, easy-to-read science-based ingredients book, this second edition of The Skin Care Ingredients Handbook is a must-have reference. And it's more than just an ingredients book! Add to the ingredients mix a healthy dose of skin science, labeling information, drug interactions, green chemistry and more and now you have even more reason to keep this handbook within reach!
