The Flakes Aren't Dry Skin.
Here's What Actually Calms Them Overnight.
You moisturize. It feels better for a few hours. Then the flakes come back, and there are more of them than there were yesterday. So you moisturize again. You buy a heavier cream. You try the oil everyone on Reddit swears by.

Everything You've Been Putting On It Is Working Against You
You've been treating a moisture problem. The flakes around your nose, in your brows, along your hairline, on your shoulders. Those often aren't dry skin at all.
Many of the oils, creams, and hair oils marketed for dry or flaky skin — coconut oil, argan, olive, and other popular natural oils — contain oleic acid, a long-chain fatty acid that research links to disrupting the skin's protective lipid layer. That disruption can mean more flaking and more sensitivity over time, not less.
And because they feel soothing on contact, you get a few hours of relief that convinces you it's working. Right up until the flaking comes back heavier. That isn't you doing it wrong. You were handed the wrong instructions.
I have searched for years trying to find a shampoo for my flakes.
Little did I know everything I was doing was feeding my problem."
Landon R., verified buyer
I was the poor sap that used coconut oil in the past thinking I was helping my skin/beard,
little did I know I was feeding the problem. I came across Dermazen while doom scrolling and figured I would give this product a shot. I'm very happy with it as it has helped clear up the irritation, flaking, itchy, annoying skin problems I've suffered with.

Putting oils on my face was the culprit.
Threw all of my oil filled stuff away and use this as a moisturizer now, even under makeup. No flare since!!

The Two-Minute Problem
Now look at what you're using to fight it.
A medicated shampoo goes on, sits for the length of a shower, and rinses off. Two minutes, give or take. That's the entire window it has to do anything. Then it's gone until your next wash, while the buildup of oil, dead skin, and product residue keeps accumulating at the scalp surface between washes.
Two minutes against a problem that runs 24 hours a day. Every wash buys you two minutes and costs you a week.
The Calming Seborrheic Serum isn't a wash. You apply it before bed and leave it on. It gets 8+ hours of contact time while you sleep, against the two minutes a rinse-off gets, and you wash it out in the morning.

What Harsh Cleansers Leave Behind
There's a second cost to the shampoo cycle.
Sulfates are the bubbly cleansers in most medicated shampoos. They can strip natural oils and leave sensitive skin feeling tight and dry. Zinc pyrithione, coal tar, selenium sulfide, steroids. Each carries its own tradeoff, and steroids in particular are associated with skin thinning over time, with rebound flare-ups when you stop.
The serum contains none of them.
No steroids

What It Actually Does While You Sleep
Three things happen across those eight hours.
First
It clears the buildup layer.
First, it goes to work on the buildup layer. Oil, dead skin, and old product residue accumulate at the skin's surface over time, and that layer is part of why so many treatments seem to slide off the problem without ever reaching it. Clearing it is what lets the rest of the formula do its job.
First
It clears the buildup layer.
Then it calms the flare-up. Redness and itching get soothed by aloe, urea, niacinamide, and grapefruit seed extract.
First
It clears the buildup layer.
Supporting the skin barrier is what makes relief hold instead of resetting every wash.
The serum has been through a third-party clinical study reviewed by a dermatologist. *27 participants applied it overnight daily and rinsed the next day, across four weeks.
*In a 4-week open-label, single-group clinical consumer perception study conducted by Citruslabs (n=27 test subjects, 18 and over). Results based on participant self-report unless noted as dermatologist-confirmed. Individual results may vary.
They Thought It Was Dry Skin Too
"Trust this product"
"I've had a very itchy scalp. I thought it was just dandruff that I could manage with dandruff shampoo. The dandruff shampoos did not help. I found Dermazen accidentally by googling dandruff prevention. Although it was a bit pricy, I was desperate enough to try Dermazen. So very glad I did. Even one application helped. My scalp is normal now and my hair is soft and shiny."

"So far so good!"
I have only used the serum once and it’s already helped immensely! I put it on and wore it overnight until I washed my hair the next day. I typically only wash my hair once or twice a week but in just one use my scalp is calm, doesn’t feel “hot”, and isn’t itching or irritated at all."

What It Looks Like When You Stop Checking Your Shoulders
Now look at what you're using to fight it.
What It Looks Like When You Stop Checking Your Shoulders
You stop scanning your collar before you leave the house. You wear the black shirt. You sit down for a haircut without rehearsing what you'll say if the barber notices.
No percentage on a chart captures that. It's just the flakes not being the first thing you think about in the morning, or the last thing you check before you walk out.
Peaceful skin, and the peace of mind that comes with it.
How the first month works
Three things happen across those eight hours.
Every night
Massage it into your scalp or face before bed, covering the whole area. Rinse with water or wash with a gentle, barrier-safe shampoo in the morning. On your face, leave it to absorb overnight.
The first week.
If your skin is very inflamed, you may feel a sting from the sea salt and tea tree oil. The aloe usually settles it within a minute or two, and it eases as your skin barrier gets healthier.
Four weeks in.
The point the clinical study measured.
*27 participants, applied overnight daily and rinsed the next day, across four weeks.
You have 60 nights to get there. See the guarantee below.
*4-week clinical study, n=27. Individual results may vary.

Questions Before You Start
Is this safe for color-treated hair?
yes, plenty of people with colored hair use the serum on a regular basis with no impact on their hair color.
I wash my hair once every two weeks. Does that work?
Yes. Apply it and leave it in. A lot of people with braids, locs, and protective styles use it as a leave-in between washes, or rinse with water and a washcloth in between.
Can I use it on my face?
Yes. Apply after cleansing and leave it on overnight. The soothing ingredients absorb while you sleep.
Stop Treating Dryness That Was Never Dryness
Eight hours of contact time instead of two minutes, and nothing in the bottle working against your skin barrier. Sixty nights to find out.
