Where to Find Your Favorite Discontinued Beauty Product

— -- The lipstick you can't live without, the perfect shade of eye shadow, your signature perfume scent. When your favorite beauty product gets discontinued, saying goodbye is just not an option.

Luckily, there are tactics to get your hands on your beloved product. Thanks to websites like DiscontinuedBeauty.com and BuyMeBeauty.com, where you can rediscover retired products, the secondary resale market is alive and well.

If your beauty product has been gone for a while, however, there may not be any more left on the sites. In that case, you can go to a custom color specialist for a close copy.

Dating back to the 1930s, Three Custom Color Specialists has resurrected more than 10,000 shades of discontinued make-up, even attracting A-list celebrities who want their beauty essentials brought back to life.

"One of our most famous clients is Angelina Jolie,” Three Custom Color Specialists co-founder and creative director Chad Hayduk said on “Good Morning America.” “We actually have had the opportunity to custom blend for her and her makeup artist a beautiful discontinued shade by Guerlain. It’s the perfect neutral lip color."

It may seem like far to go, but discontinued beauty product buyer Jennifer Fisherman-Ruff thinks it’s worth it.

“When you love what you love, you want it,” she said on “GMA.” “I found a lip gloss that I loved so much from Chanel, so then I purchased 27 of them.”
