Use it as the last step of your skincare routine. Spread 2 fingers' worth of sunscreen on your face & neck, add a palmful for any other exposed area. Massage on skin till the product has completely blended in. We recommend using this sunscreen 20 minutes before sun exposure and re-applying every 2-3 hours. Derm Tip: Pair this sunscreen with our Ashwagandha & Alpha Arbutin Melasma Serum Cream for double-duty defense: sun damage and pigmentation.
