Clean Skincare That Actually Cleans

Safe, gentle and effective ingredients.

100% NATURE-DERIVED INGREDIENTS

Your skin acts like a filter. Not everything gets through, but some things do. That’s why we leave out anything synthetic and focus on what matters: clean ingredients that are safe, gentle, and effective.

ONE BAR DONATED FOR EVERY BAR SOLD

One for you, one for our community. 8,000+ bars delivered citywide through ongoing partnerships with Food Bank For New York City and The Bowery Mission.

FORMULATED BY A CHEMIST

With a background in biology and formulation chemistry, I choose nature-derived actives that deliver real results. I’m obsessed with ingredient integrity and how skin actually behaves. B&L delivers products you can trust and results you can feel.
