What Our Customers are Saying about Our Balancing Phage Serum

"Awesome product"

"I enjoy how this product feels on my face - it is light and refreshing. After just one night of using the serum, my face cleared up from larger pimples and overtime, I noticed less blackheads."


"Highly recommended. This is better than my prescriptions!"

"I used a lot of other products and even prescriptions to try and improve my breakouts, but nothing has worked as well as the Wild Resilience* serum. Many people have noticed how improved my skin looks!"


"Highly recommended. This is better than my prescriptions!"

"I've struggled to control my acne for years and tried everything over the counter and prescriptions to tame it, but everything just dried out my skin, causing more breakouts later. The Wild Resilience* serum is my answer. It clears major breakouts quickly and keeps them away. Seeing photos of myself from before, it shocks me just how much better my skin looks now. The B/A pictures attached are only after two weeks!"

I wish I had this product years ago, I can't say nice enough things about it! My misbehaving skin has card down and is actually glowing!

Awesome product

I cannot imagine a world where I don’t have this product. Ellis Day has created something that is magical. It doesn’t irritate my skin at all. It’s done something that I hadn't thought was possible for my acne and I am incredibly thankful to the Ellis Day team. If you have struggled with acne, this is what you need.

Very happy

I wanted to wait at least one full cycle to review since my acne is hormonal. After a month and a half of use, I'm very happy with this product. While my skin is not 100% acne free (and I'd never expect one product to manage that), I am definitely having fewer breakouts, fewer clusters/patches of breakouts, and fewer cystic breakouts that linger for weeks. The breakouts I do get often come to a head more quickly as well. I knew I'd have to be extremely happy with this product to keep using based on the price but I'm now sure I'll be reordering. Going to try it on my back next because it's been so effective on my face!

Amazing product

This is a wonderful serum! It goes on so smoothly and does not pill or easily come off like other products do. It has made a great difference in the texture of my skin and now I cannot do without it!

My skin needed this.

I've been using the Balancing serum for the last three weeks. I am 41 with adult acne and my skin is sensitive. This has completely reduced inflammation and reduced breakouts. I highly recommend!!

Can’t go without it!

Firstly let me start by saying I LOVE the ladies at Ellis - the products they are creating are truly revolutionary (with solid science to back them) and a customer support that is the best I’ve had of ANY skin care line. I’ve been using the balancing phage since November and I absolutely love it. I recently went off birth control - the last time I did that it caused really bad hormonal acne - this time I started using the phase serum and I’ve had no issues with hormonal deep cystic acne like I use to. I basically haven’t had any mayor breakouts since I started using it! Which is still shocking to me. It’s such a beautiful primer for your skin - It feels like all my other products - retinoids, vitamin C, etc now apply so much smoother and effectively - it turns your skin into a perfect canvas for the rest of your skin care routine. Big fan!!! Won’t go without it.

New staple

This is my new favorite product! I wish I had heard and learned about this sooner. I would trade any of my skincare products for this. The customer service is really good as well.

Definitely helps clear skin!

I like this product and definitely would say it helps clear skin / renewing in my case. (I did have a facial maybe 3 weeks ago so I'm sure that also added to improving my skin a bit) Although I did notice less pigment spots before the facial. My pictures below are not filtered at all and you can definitely see a difference. My only complaint is it was a bit too watery for my liking and definitely needed moisturizer afterwards as it did make my face feel a little on the dry side afterwards.

I feel a difference!

It’s been a few weeks getting close to the end of the bottle.... I do feel a difference not sure about huge changes overall maybe I’ll need to use for a time but skin is smoother, hormonal acne is still happening but less duration I will continue using and see if there are further improvements and update 👍🏻 so far happy!
