The Beauty of Joseon relief sun plus probiotics at 50 ml sunscreen is a tried and tested product that has really been popular for quite some time so I really find it a great steal when it was offered at markdown price thanks to style Korean’s promo offering.Hence out of curiosity,I got one and voila! it was really effective in making the skin dewy especially during those dry humid days when moisturizing is not enough it really helps with it’s lightweight formulation that easily glides upon application.
Did not like this sunscreen. Feels too heavy and leaves face really oily and broke me out.
Love it….

it’s not worth the hype. I feel it’s overhyped, but it really works if you have dry skin.
Good quality.
