What's Included


Parallel's Skin Microbiome Discovery Kit allows you to understand your skin health and age to support clarity and better aging. Parallel uses the most advanced sequencing technology available today. This kit contains four swabs and two oil strips to test different areas of your facial skin microbiome. The resulting skin health report provides an assessment of your skin microbiome type, skin age, bacterial assessment, as well as holistic recommendations across food and skincare ingredients. We also identify bacterial overgrowth associated with acne-prone and eczema-prone skin, along with imbalances associated with other skin issues correlated with melasma, rosacea, psoriasis, and hidradenitis suppurativa. By understanding your skin microbiome, you can choose the right products at the right time. Conducting the test is easy, requiring less than a minute. Video tutorials and step-by-step instructions available with every kit. Results provided within 2-3 weeks.10-min consultation with Parallel physician included.


Your first bottle of Active Phage Serum (4-6 week supply) targeted for your skin microbiome type; selection to be shipped after results of your test are delivered. Our various phage serums have the ability to support eczema-prone and acne-prone skin, amongst others. With this bundle, we offer a 30-day money-back guarantee on your custom active phage serum.

Worked overnight!

I've had a very red, painful, cystic bump on my chin from an ingrown hair and shaving. I tried to get rid of it with other products and extraction, which seemed to make it worse. A friend suggested that his custom phage product from Parallel might work for me, too. Overnight, the pain went away and it's much less red. This stuff works! I'm impressed and about to purchase my own.

This Product Changed My Skin!

Most recently, I have battled persistent acne, and it seemed nothing I tried could truly clear my skin. New breakouts appeared weekly, and I grew increasingly frustrated as expensive cleansers, serums, prescription medications, and facials failed to provide lasting results.

Then, I discovered this facial product, and it has absolutely transformed my skin! The breakouts have ceased entirely, and my complexion is the clearest it's ever been. I have integrated these serums into my daily skincare routine, and I will never go back.

This has worked for me like no other product!


Within just one week... I noticed a remarkable difference in my skin...leaving behind a noticeably clearer and healthier complexion. It's as if this serum understood my skin's needs like no other product before.


I spend so much money and effort on beauty and preventative care only to be stuck in a cycle of trial and error. Our skin and what it needs to be healthy is so personal, so the moment I saw Parallel, I was sold.

Parallel is a fully comprehensive experience with testing, personalized products, and clinical guidance. I was impressed with the test, which provided my skin microbiome type and skin age, as well as skincare recs and food guidance. With Parallel, I know that what I'm getting is exactly what my skin needs to function properly and look its best. But what's awesome is that in addition to data, I also have access to scientists and doctors who help guide me through the journey.

After using Parallel's product line (cleanser, phage serum, and moisturizer), my skin feels fresh and radiant. The ingredients are all really high-quality. I'm now also thinking about getting a personalized anti-aging prescription. Honestly, I'd be hard-pressed to go back to buying mass-produced products when I've experienced Parallel. It's like driving a Tesla. Once you try one, you've entered the future, and all other cars seem outdated.
