I've just started retin a (tretinoin) 0.05% on my face, neck and hands. What's an oil free sunscreen you'd recommend I use? And what SPF 30 or 50 thanks!

Skinceuticals. Skinceuticals Physical Fusion sunscreen is water resistant, oil free, paragon free, tinted sunscreen 50 with a lotion consistency. You cause 30 for regular daily exposure and 50 if out in the sun for a long time. May have to repeat every 2 hours.
