Balancing Phage Serum

I received a sample in the mail like two months ago, and I loved it that's why I ordered the mini duo. It really helped with my breakouts in the chin area, it worked like magic! Overnight, redness and inflammation disappeared and in two days, they're all cleared up. It is now a staple in my skin care, and I do not need to use a toner anymore.And 7 ml mini bottle goes a long way! Will definitely purchase again. Two thumbs up to the ladies behind Ellis Day! Keep it up! Appreciate receiving a personalized note from Carol, too. Thank you so
much. Enjoy the holidays!

good so far

Easy and clean - feels good and notice a little difference in my skin after 2 weeks. Hoping for continued good results as I use it :)

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.
