I chose this product as one of my free birthday rewards for March. I'm so glad I did because it truly has improved my skin after the first use! I HIGHLY recommend this! I definitely recommend using after you cleanse your face and before using any serums or moisturizer. OR you can really just use this product and it makes your skin feel great, no lie🙌🏼

It's hydrating without being too heavy. Makes my face feel soft stressed and absorbs pretty fast.
