VVBETTER - queque062 review for Teca Lifting Moisture Serum

I received this product for free from Picky and VVBETTER in exchange for my honest review. The package is the first thing that amazed me. It is a twist lock cap with a dropper. So luxury design also keeps serum fresh. It is so hydrating and has no sticky feeling. I only use serum during the night. I feel in the humid hot area, using toner plus serum in the morning is too much. Used it for 2-3 weeks at night. I can tell my skin is smoother, especially around my mouth where used to be rough.Another great thing is that It does not contain any scent. Even people with sensitive skin can enjoy it. It contains 8 types of peptides that make skin firm and patent “TECA” which make skin barrier stronger. It contains brightening ingredients such as Vitamin C, Niacinamide. For the brightening and firm effect, I think I need to use longer to check these benefits.
