Emily Mariko's Must-Have Products, From Diptyque to Linen Sheets

Mariko does not go a day without her trusted lip balm, the Aquaphor Lip Repair Ointment ($5). "It's a comfort thing. I've repurchased since I was 12 years old, and it's just the one product that's stayed consistent in my beauty routine for years," she says.

The sensitive skin-friendly lip balm contains conditioning ingredients like shea butter; vitamins C, E, and B5; and calming chamomile essence. It also leaves a subtle glossy finish for a healthier-looking lip.

Pro Tip: Mariko mainly uses it on her lips, but she also uses it around her nose when she has a cold or on a dry patch around her eyes.
