I love, love, love this product. So hydrating. I do not want to be without this in my life!

Does what it says!

I am really impressed by the Custom Hyaluronic Acid Serum. It lasted me for three months of daily use and I only used it in the morning because it provided a great amount of moisture and plumpness for my mourning routine and at night I like to use a more anti aging serum. My serum also had niacinamide and it evened out my skin tone and eliminated redness around the center of my face that I basically had to use less foundation. Overall, a great product and I plan to reorder.

Good for a minimalist routine

I'm only 30, but I'm a type A, proactive type of person and I wanted to get a head start on avoiding aging. I really like that with this product I can deal with my acne AND prevent aging. It fits in with my minimalist philosophy to not have to use more than one product per day. However, I will say that I was so impressed with the efficiency that you get out of one of these custom serums that when it was time for a refill I went ahead and ordered the set of this serum plus the oil one to use at night.

Very Effective!

Ever since I have began using my hyaluronic acid and vitamin C serum in January, my skin has cleared up noticably. I haven't changed anything else in my skincare/diet/supplements etc., so I am sure that this product has made a huge difference. For reference, I am 27 and struggle with congested skin and some mild hyperpigmentation and I get decent breakouts that are hormonal in nature and worse around my cycle. My skin has appeared much less congested and my breakouts in between my period have almost gone away. My skin also feels much smoother as well. The product is effective, affordable, and I have had an overall wonderful experience with it!




I really appreciated the personalization of this product. I had some issues with my first batch, but didn't feel it was worth making a big deal about — however they insisted on taking a look at the ingredients and working with me to get a second serum that was much more to my liking. It's been great for my skin and I couldn't be more happy with it! Really excellent service.

We're really happy that we could help you, Sean. Thanks for reaching out when you needed your formulation tweaked. We're also glad that the tip on cleansing with micellar water turned out to be helpful! Let us know if there's anything else we can do to help, now or in the future.
A new must have in my mature skin routine

This hyaluronic acid serum was custom-formulated to match my mature dry winter skin. To determine my needs I had answered a few qs before submitting my order. I was slightly anxious that the formula might arrive too greasy & too heavy as my questionnaire replies were always on the extreme end of dry.

However, this serum exceeded my expectations. It makes my winter dry skin hydrated & plumed. It is light but not watery nor oily, it doesn’t leave your skin sticky either. After I received the Maya Chia Super Couple from my BH box, I tried the Activist Serum with the Maya Chia serum only to discover a powerful duo. This is not to say that the Activist’s own Custom Precious Oils Serum is not a good combo - I just happened to try my routine with another potent type of serum. I can see why the Activist skincare sells their products in pairs (serum + oil) for the best results.

This is a high-performance clean skincare that will leave your skin deeply hydrated.
Bonus: shipment to Canada, unheard of only $5.

We are really happy that your formulation (with the active ingredients vitamin C, green tea and niacinamide) is working out for you! We agree, combining an oil-based serum with the Hyaluronic Acid Serum in your regimen is a great way to go. And we are proud to be able to make shipping to Canada affordable. Thanks so much for giving us a try, and we hope to see you back here in the spring!

It is an incredible opportunity to have a serum custom created for your needs. And this is a high quality serum, very potent. I noticed how my skin became so much more hydrated and plump. It absorbs effortlessly and has very mild scent. I enjoy using it!

Natalie received niacinamide, licorice root extract, and green tea extract in her custom formulation. We're so happy you like it, Natalie!

This is a star product for me. I absolutely adore this serum. Hand in hand with the other serum, my skin has been absolutely AMAZING. This was so hydrating, yet gentle for my super sensitive skin. This natural serum was absolutely wonderful. Please try this, you will not be disappointed!

We're so happy your sensitive skin is loving the serum! Thanks for the update, Sammy :) We used green tea extract, niacinamide and lotus extract in her formulation.
In love!

The inner beauty of this serum is just as amazing as the outer beauty!
I have been so happy with this product since the moment it arrived on my doorstep. I decided to order it pre-mixed and the consistentancy of the product is thick which makes it so wonderful to apply. It feels great going on and my skin has been feeling so rejuvenated since I have been using it.
I highly recommend!

We used niacinamide, licorice root extract, and our alpha hydroxy acid blend in Whitney's custom formulation. So glad you're liking it, Whit!
