People often assume that because I’m Paula Begoun’s assistant, and given that I work alongside The Cosmetics Cop Team who reviews products for the most comprehensive beauty resource in the world (Beautypedia.com), I must know all the latest and greatest makeup and skin-care products. While I do feel blessed to have such invaluable knowledge at my fingertips, I still sometimes struggle when shopping for cosmetics. In some ways, the more I learn, the harder it becomes.

Fortunately in the realm of skin care, I’ll never have to gamble another dollar on a “miracle treatment” again. Since I started using Paula’s Choice products my skin is in the best shape it’s ever been, and I can rest easy knowing that I’m only using ingredients that have proven benefit for skin. (Not to mention the fact that Paula wouldn’t hire me unless I agreed to stop tanning, and I can already see my skin is better for it.)

But shopping for makeup, on the other hand, is a different story. While I used to impulsively stroll into Sephora for my makeup fix, I am now all too conscious of what’s lurking on those shelves. Are the ingredients bad for my skin? Is it worth the price? Is the packaging conducive to the active ingredients? Does it contain fragrance? Will it live up to the claims? How does it compare to other products in the category? Despite my efforts to research products on Beautypedia.com before I leave the house, once I’m surrounded by a sea of options on display I can’t help but be tempted to stray from my list. It’s frustrating because I know that even if something looks great initially, it may not be good for my skin below the surface or have the longevity I’m looking for.

Then it dawned on me… hello, the name of Paula’s book is Don’t Go to the Cosmetics Counter Without Me! So I did just as the title says and hit the stores with my copy of the book knowing fully well that I’d be attracting attention from every salesperson in sight. Some were intrigued or impressed, while others were apprehensive, but either way I had peace of mind knowing that I didn’t have to second-guess whether or not a particular mascara would end up flaking by the day’s end or if that long-wear lipstick really held true to it’s name—all the answers were right there in the palm of my hand.

Interestingly, the instant I pulled out the book the sales pitch changed. It’s as if the consultants realized they weren’t going to be able to pull the wool over my eyes. One woman, who was trying to sell me a kit of products including an eye cream, completely changed her tune as soon as I spoke up about Paula’s theory about eye creams. She went on to not only agree with my point, but then also began recommending products from a line other than the one she was working for. What a breath of fresh air!

Another salesman wasn’t so congenial. He watched me as I flipped through pages of the book and exclaimed, “Oh honey, that is so cute,” as if to say that I was so naïve in the world of cosmetics. I didn’t let his demeaning attitude get to me. Instead, when he began rambling on about how magnificent a particular line of products were, I cut him off and told him “Thank you, but I’d rather look it up in my book.” The look on his face was priceless!

Would I go shopping with my copy of Don’t Go to the Cosmetics Counter Without Me again and again and again? In a heartbeat! Not only did I have peace of mind and a more informed experience with salespeople, I also had a quick and easy way to shut them up if need be!
