„I’m all about investment pieces and that includes my skincare. When you find something that really works, that’s so potent and pure, it’s transformative.

Apply in the morning on cleansed skin as a luxurious prep. Before bed, layer on again for an overnight treatment that feels like a cashmere hug. 

I like to apply Skin Activator and follow with Suprême C for skin that feels incredibly balanced and satiated. The combination of the two is otherworldly—it’s like everything is bouncing back.

The unique gel-oil texture of this Vitamin C concentrate leaves my skin intensely hydrated, but you can always follow with a favorite moisturizer directly and add SPF as a final daytime step.

Bonus Tip! A little goes a long way. start with 1-2 pumps, enough to cover your face, and pat any excess onto neck.” – Gucci Westman, Founder.
