Love this product

Such a great product. My skin glows and stays hydrated every time I use it. It’s a must have in my skincare arsenal!

Andrea S. (Albuquerque, NM, US)

I started off with the travel/trial set to try out a variety of products and after the first week I was obsessed! Activist Skincare is exactly what I was looking for when it came to high-quality products and sustainability. After a few simple questions I was able to set up a convenient subscription to fit my needs based off how often I would be using each product. They also go above and beyond with the packaging and even go as far to leave a handwritten note inside the box. I would 100% recommend to anyone looking to change up their skincare routine with sustainable products.

Love it!

This is a great serum! After a few weeks of using it, I can tell that my skin takes in moisturizers much better. Some of my dark spots are lightening too! I signed up for the membership and got the sweetest note and a sample of the precious oil :) Love this company and what they do.
