Siggy Flicker is best known for her lengthy career as a relationship expert, but she also happens to be well versed in another area: skin care, at least when it comes to this specific brand. For over 20 years, the Real Housewives of New Jersey star has sworn by Dr. Zein Obagi‘s ZO Skin Health products and she’s revealing her favorite ones!

The 49-year-old mother of two initially began visiting Beautiful You by ADA in Boca Raton, Florida to seek help for her skin issues. The facility specializes in everything beauty and body rejuvenation.

Siggy battled with dark spots and discoloration in various areas on the skin, so owner Ada (Shepard) insisted she use Dr. Obagi’s products. Twenty years down the line and the reality star still can’t get enough of them.

“As soon as I started using the products, it was an overwhelming response,” Siggy told People. “Everyone was asking me what I was doing to get such beautiful skin and I owe it to ZO Skin Health products. My favorite products are the Melamin and Melamix. I mix them together and they take away all of the impurities on my face.”
