Sulwhasoo Jaumsaeng Serum, bought with my own money

It is a serum from such a famous brand that there is hardly anything to explain, but it is well-known for its anti-aging benefits. It is excellent for basic skincare, and if I apply it before makeup, my skin gets a natural glow for a beautiful finish. It absorbs exceptionally well and is effective for improving skin elasticity and reducing wrinkles, so it is a serum I use consistently.
