Numbersin No. 6 Serum Review

The advantage is that it is moisturizing and not sticky, making it a perfect match for my oily skin. The bottle itself has a transparent feel, and the texture is watery, making it the best item for those with very oily skin. In the summer, stickiness is uncomfortable when you wake up, so this is great for the upcoming summer. However, the downside is that although it claims to be a serum that helps you sleep soundly for 6 hours... it isn't quite that deep. I think the advertising is a bit exaggerated. It is just okay for simple basic skincare. Also, I think it is a product worth buying at a discounted special price at Olive Young rather than at full price. The regular price might feel a bit wasteful. I used to love the No. 3 Serum, but this one is too watery, and I didn't notice much of a difference the next day, so I recommend the No. 3 Serum instead.
