These Are January Jones's Go-To Beauty Products 

Jones turns to this lightweight Kérastase mask when she needs to revive her dehyrdated strands. I have really fine hair, and this mask doesn't weigh it down," she says. "I normally leave it in for five minutes, but if I need extra moisture, I keep it in for 30." 

For an instant slimming effect from head-to-toe, Jones slathers on this rose-scented elasticity-boosting cream. "It's for face, neck, legs, arms, and anywhere that needs firming," she says. 

Betty Draper wouldn't be Betty without her matte red lip, and it's a classic beauty look that Jones routinely visits herself. Although she's tested many bullets throughout the years, nothing compares to this Chanel shade, "I have so many great reds, but this one from Chanel is my favorite," Jones reveals. "It's the perfect shade for my skin tone."

Between regularly using heat tools, brushing, and coloring hair, split ends are inevitable. To help prevent future strands from splitting, take a cue from Jones and use an oil such as this one from Kérastase. "I like to put this on my ends before blow-drying, when my hair is still damp. It prevents them from splitting," says Jones. 

If you have sensitive skin and you're in the market for a gentle multitasking skin care product, look no further than this product in Jones's arsenal. "I have sensitive skin, and this retinol product doesn't irritate it at all. It gets rid of blemishes and wrinkles. It's been a game changer in my skin-care routine," explains Jones.
