Here's How Much Chrissy Teigen's Skin-Care Routine Costs

The product Teigen uses from her aesthetican's line is the Shani Darden Skin Care Retinol Reform Treatment Serum ($88). Encapsulated retinol in the serum makes the formula non-irritating. That, combined with AHAs, helps reduce fine lines and wrinkles and improve the skin's overall tone.

Just be careful when using retinol in the morning. It's best to use this powerful ingredient in your nighttime routine, because it can make your skin more sensitive to the sun. You also shouldn't use this product while pregnant or nursing.
