This is a b.glen trial set. The facial cleanser has not been used. The hydroquinone serum was used for 4 days, so about 30% remains. The other items were used for about 2 days. I purchased it from the official website, but the shipping label was attached directly to the box, so part of it is peeled off. - Brand: b.glen - Set Contents: 7-day Special Set - Product Type: Skincare - Program Number: 1 - Purchase Date: August 2025 Thank you for looking.
