How It Works

Our PM serum delivers thousands of microscopic spicules, with soothing centella and PDRN, into your skin. Like microneedling, they create tiny micro-channels that switch on your own collagen production, so acne scars fill in from underneath over time.

What's Included?

1 Cica Centella Microneedling Serum (50 ml) + 1 PDRN Centella Microneedling Serum (50 ml)

Shipping & 90-Day Guarantee

Orders ship within 1-2 business days and arrive in 7-13 business days, tracked.

Every order is backed by our 90-day money-back guarantee: if you don't love your results, we refund you in full.

Real skin, real doubts, real results

"I was sure it wouldn't work on me."

Every one of these women had a reason not to try KOEC. Here's what changed their mind.

Before and after
"I've tried everything"
★★★★★

Ten years of products. This was different.

Creams sit on top of the skin, so of course they never touched my scars. This actually gets underneath. By week three I could see the edges softening. If you've given up, give it one month.

Jordan S. · verified buyer

Before and after
"My scars are too deep"
★★★★★

Old boxcar scars, finally shallower

Mine were 8 years old and I assumed only lasers could touch them. Two months in they're visibly shallower, and the dark marks around them are almost gone.

Katelin C. · verified buyer

Before and after
"Microneedling is cheaper at a clinic"
★★★★★

Cheaper than ONE derm session

I was quoted $400 a session, 4 sessions minimum. I've already had better results with this at home, with no red face for three days after.

Jasmine T. · verified buyer

Before and after
"Will it make me break out?"
★★★★★

No purge, no new breakouts

That was my biggest fear. It never clogged a pore. My active acne actually calmed down first, then the scars started fading. I've stopped wearing foundation.

Nina S. · verified buyer

Before and after
"Does it hurt?"
★★★★★

A tingle, not pain

You feel a light prickle for a minute, that's the crystals working. It fades fast and the next morning my skin is calm, not red. Honestly I've come to like it.

Dharma K. · verified buyer

Before and after
"Probably another gimmick"
★★★★★

I bought it to prove it wrong

Skeptic here. I took photos every week expecting to return it in 90 days. I never sent it back. The photos did the convincing.

Microcrystal technology in the skin

Why it works when creams don't

Microcrystal Technology

Scars live below the surface, which is why creams can't reach them. KOEC's serum carries thousands of microscopic spicules, paired with soothing centella and PDRN, that create tiny micro-channels, exactly like microneedling does.

That gentle micro-trauma tells your skin to rebuild its own collagen. Night after night, the scar fills in from underneath while the actives fade red and brown marks on the surface.

Questions & answers

Everything You Want to Know

Can I use this if I'm still breaking out?

Yes. It's non-comedogenic, so it won't clog pores or cause new breakouts. Centella also soothes active, irritated skin, so most customers see breakouts settle before the scars start to fade.

Is it safe for sensitive skin?

It's built around soothing cica (centella asiatica) to calm reactive skin. If yours runs sensitive, use it every other night for the first week and build up as your skin adjusts.

What kinds of scars does it work on?

All depressed (atrophic) scars, boxcar, rolling and icepick, including old and deep ones. It also fades pigmented marks: red PIE, brown PIH and general discoloration.

Will it work on my skin tone?

Yes. The microcrystals work on the structure of the scar itself, so results don't depend on your complexion. And unlike lasers, there's no heat, so no risk of laser-related hyperpigmentation on deeper skin tones.

How long until I see results?

Most customers notice softer, brighter skin in the first one to two weeks, smoother texture by month one, and visibly shallower scars by month two to three. Collagen takes time to rebuild, which is why we give you 90 days to judge it.

Does it hurt? Do the crystals stay in my skin?

It doesn't hurt. You'll feel a light tingle for a minute or two as the microcrystals work. They break down naturally and don't stay lodged in the skin.

Can I use it with tretinoin and makeup?

Yes. It's a PM serum: apply it at night, and if you use tretinoin, alternate nights for the first two weeks. Makeup goes on as normal the next morning.

What if it doesn't work for me?

Then you don't pay. Use it for up to 90 days. If you're not happy with your skin, contact us for a full refund, no questions asked.

Your 12-month journey

What nightly use actually looks like

Scars live deep, so progress is gradual, then unmistakable. One serum, every night, before bed.

✦Night 1
FIRST FEEL

The microcrystal tingle kicks in

Within seconds you'll feel a light, prickly tingle, the spicules opening micro-channels so the actives reach where scars actually live.

"You can instantly feel it working. I like the feeling." Jordan S.
○Week 1
EARLY WINS

Softness, then glow

The prickle softens, hydration improves, your other products absorb deeper and the surface feels noticeably softer.

◐Month 1
VISIBLE PROGRESS

Smoother texture, calmer tone

Active acne calms, redness fades, pores look smaller. The makeup you used to fill in texture becomes optional.

"I literally don't have to wear makeup anymore." Nina S.
◑Month 2
TURNING POINT

Scars are noticeably smoother

Boxcar and rolling scars soften as collagen rebuilds. Dark spots and PIE / PIH start fading.

"I went on a date last week without even thinking about my skin." Katelin C.
●Month 4

Deep scar repair becomes obvious

Results start to rival in-office microneedling, without the redness, downtime or four-figure bill.

❖Month 6
HALF-YEAR MARK

You forget you had a skin problem

You stop planning your day around lighting and angles. Selfies, mirrors and close conversations stop being a worry.

"I didn't realise how much mental energy my scars took up until it stopped." Rachel M.
♛Month 12
THE TRANSFORMATION

You don't recognise your old skin

Smooth, even, glowing, bare. No filters, no angle tricks.

What Our Customers Say...

The questions people ask before buying, answered by people who already did.

"I have super sensitive skin"
★★★★★

Gentle but powerful

Rosacea-prone and nervous. I started every other night like they suggest. Zero irritation, and my marks are fading fast.

Amanda K.

"Does it work with tretinoin?"
★★★★★

Fits right into my routine

I alternate with tret and it's been fine. My skin actually tolerates tret better now, and the texture is the smoothest it's been in years.

Michelle P.

"Will it work on dark skin?"
★★★★★

Finally safe for my skin tone

Lasers left me with more dark spots, not fewer. This faded my PIH without any of that. Even tone for the first time in forever.

Rachel B.

"How long does it take?"
★★★★★

Patience paid off

Week 1 softer skin, month 1 smoother texture, month 2 my scars were obviously shallower. Not overnight, but real. Get the 3 month supply.

Emily R.

"Is it worth the price?"
★★★★★

Cheapest thing that ever worked

I'd spent hundreds on creams that did nothing. This costs less than one facial a month, and it's the only thing that's changed my scars.

Lauren H.

"What if it doesn't work?"
★★★★★

The guarantee got me to try it

90 days to decide felt like no risk at all. I'm on my second order now. Wish I'd stopped overthinking it sooner.

Jessica T.
