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.

Liquid Goodness

Finally found Activist when I was trying to move zero waste with my skincare, and I am so pleased! Shipment is seamless and recyclable! This active hydration lives up to the name as it actively hydrates your face! I have been so happy with this product and plan to continue using for a long time!

Slippy, smooth, and refreshing!

I love everything about this serum. It's the perfect hydrator for me. Makes my skin feel so good and sets me up for Precious Oils. My skin has never been so clear and glowy before using this 4 step system! I am obsessed!

Great at improving skin hydration

I’ve been using my full-sized Activist products for about a month now (after using the sample kit for a few weeks), and I’m in love with the entire routine. I alternate between the two serums, using the Active Hydration each morning. I was having terrible problems with dry skin during the Winter months before starting the Activist routine, and I couldn't be happier with how fast my skin health and hydration improved.
