Summer Fridays' Marianna Hewitt and Lauren Ireland Share Their Must Haves

Ireland loves incorporating LED light therapy into her skin-care routine. For a great at-home mask, she recommends the Pro LED Light Mask ($1,900) by Shani Darden, a celebrity aesthetician who works with the likes of Chrissy Teigen, Shay Mitchell, and more. "It's certainly an investment, but I love this mask because it addresses all of the common skin concerns like acne, pigmentation, [and] aging, and it boosts collagen," Ireland says.

Pro Tip: Different colors of LED light give you different benefits. Blue light is said to help fight acne-causing bacteria, red light is great for antiaging, and yellow light helps boost collagen production and reduce inflammation. The Shani Darden LED Mask is FDA-cleared and includes a neck attachment for extending the treatment beyond just your face.
