Marine Care Retinol Gesichtsserum 50ml

I've been using this 50ml serum every night for a month and my forehead lines look noticeably softer. The texture sinks in fast without any greasy residue, which is exactly what I need under my moisturizer.

Three weeks in and the 50ml bottle is still going strong, which is rare for a retinol serum. My skin handles it well even on sensitive days, no irritation, and it sinks in fast before moisturizer.

The dropper gives just the right amount for my whole face, and the 50ml bottle has lasted me over two months of nightly use. My skin feels smoother in the morning, and it hasn't caused any irritation like I worried retinol might.
