Lira Retinol Serum-LOVE!

Jasmine was right on when she suggested I try this serum to replace my current skin care (The Ordinary). Not only does it feel lovely, it has a pump that helps the serum stay fresh and WORKING for the entirety of the bottle. After using this serum for a while I really do see a difference in my skin and how smoothly my makeup goes on. (FYI-I am also using the enzyme cleanser, the BIO Hydra C serum from Lira as suggested by Jasmine.)

Great product!

After just one month of using the Lira Pro C4 Retinol Serum I’ve noticed clearer skin tone, a smoother forehead, and smaller pores next to my nose. Love it! Smells great and no irritation for my sensitive skin. Jasmine makes the online ordering processing easy, highly recommend!
