Frequently asked questions
Does the Round Lab Birch Juice Sunscreen leave a white cast?
No — it uses chemical UV filters that blend into the skin without an obvious chalky finish. It leaves a dewy, moisturizer-like finish rather than a matte one.
Is it good for oily skin?
The dewy, moisturizing finish suits normal to dry skin best. Oily skin may find it too rich or shiny, so a lighter gel SPF may be a better fit.
Does it contain essential oils?
The official ingredient list includes chamomile flower oil and pine leaf oil, which can matter for users sensitive to aromatic botanicals. Patch-test first if you react to botanical oils.
Can I use it instead of moisturizer?
It is positioned as a moisturizer-like sunscreen, and many normal-to-dry skin types use it as a hydrating final step. Very dry skin may still want a separate moisturizer underneath in winter.
