CKD Guaranteed - Heyitscli review for Retino Collagen Small Molecule 300 Cream

I received this product for free from Picky and CKD in exchange for my honest review. These two have been in my collection for a while. I enjoy applying the collagen mask because it firms up my skin and leaves it glowing the next morning. It also has a cooling effect. Every time I think my skin needs extra hydration, I use it. I'm hoping for any improvements on my neck with the cream, but I'm not seeing any yet. Since retinal is a very delicate substance, it makes sense to use it exclusively at night.
