“I use Biologique Recherche P50. It smells intense, but it’s supposed to tighten your pores. You can feel it tingle when you dab it on—you’re not supposed to wipe it on. I went to this facialist in the Valley for a few years and she exclusively used Biologique Recherche products. I loved going there because part of her routine was to use these pulsating sponges to help you better absorb the product and to tighten your skin—it makes you look like you’ve had an instant facelift. I stopped using Biologique Recherche for a while, but my skin felt like it was out of balance, so now I’m back on.
I’m at the age where I have to start thinking about the under-eye lines and stuff. I don’t necessarily care about aging—I think aging is beautiful—but I also want to try and maintain things for as long as possible.  When I want to be more dewy, I spray Biologique Recherche Fluide VIP O2 on my hand and then pat it on my face to look extra glowy. It’s apparently supposed to protect your skin from environmental damage.
When I want to do a fun mask, Biologique Recherche Masque VIP O2 is a super yummy, ultra hydrating treatment that’s especially good for under my eyes. I put it on for 10 minutes. None of their products really smell great, but I feel like that’s why they work? [Laughs]
Biologique Recherche Masque Vivant smells like yeast. It’s awful. What you’re supposed to do is mix a little bit of it with baking soda to make this weird foam, and then put the foam all over your face for 15 minutes. It makes you feel so clean; it’s like my pores have been excavated. Frankie told me about the baking soda part. The mask is super emollient and thick, so when you add the baking soda it foams up and becomes light and frothy. Whenever my husband (Ryan Adams) catches me with the mask on, he makes fun of me, like, ‘Oh, I didn’t know you were in [the band] KISS today.’ [Laughs]”
