i didnt want to buy another product to fix my face, but this ended up being the best purchase of my life, fully worth the price
Three steps happen every night you apply — no needles, no downtime.
The tiny spicules in the serum penetrate into the layers of your skin and deliver active ingredients, much like microneedling does. Over time, this process supports natural collagen production and helps fill in the look of acne scars.
Real hydrolyzed sponge spicules, magnified — the same microcrystal structures at work in every application.
Yes. Microcrystal Serum PM is made to work alongside active acne, not against it — it won't clog pores or cause new breakouts. You can keep using it consistently through breakouts while it goes after the scars left behind.
It is. The formula is fragrance-free and allergen-free, so there's nothing in it built to irritate reactive skin. If your skin runs sensitive, start every other night and build up as it adjusts — that's exactly why this Duo includes a milder strength.
Depressed (atrophic) scars — including boxcar, rolling, and icepick types — along with pigmented marks such as red PIE, brown PIH, and general discoloration.
The Duo pairs a 2000-strength Mild formula, best for beginners, with a 5000-strength Strong formula for experienced users. Start mild, then move to strong once your skin has built tolerance.
No. Microcrystal Serum PM is designed to be used entirely at home — no lasers, no microneedling appointments required.
It doesn't hurt. You'll feel a light tingle as the microcrystals get to work — that's it. They dissolve into the skin and don't stay lodged in or under the surface.
Yes to both. It layers with the rest of your routine, and makeup goes on as normal afterward. It's a PM serum, applied at night before bed.
Scars form the same way regardless of gender or age, and this serum is formulated to work the same way in response.
Mericube Serum PM Duo pairs a mild formula for beginners with a strong formula for experienced users — so your skin always gets the right intensity as it adjusts.
Best for beginners. Start here to let your skin acclimate to nightly microcrystal treatment.
Best for experienced users. Move up once your skin has built tolerance, for a more intensive treatment.
YOUR 12-MONTH JOURNEY
Acne scars live deep — so progress is gradual, then unmistakable. One serum, every night, before bed. Here's the path most customers walk, week by week.
Apply, press, and within seconds you'll feel the spicules activate — a light, prickly tingle most customers describe as “weirdly pleasant.” That's the serum opening micro-channels in the skin so the actives can reach where scars actually live.
By day 3–4, the prickle softens and your skin starts feeling hydrated. Your other products absorb deeper, and the surface feels noticeably softer to the touch.
The first visual cue: skin looks brighter under bathroom light, and the dull, uneven look begins to lift.
Redness fades and pores look smaller. The makeup you used to need to fill in texture starts becoming optional.
The depth of boxcar and rolling scars begins to soften as collagen rebuilds in the dermal layer. Dark spots and post-inflammatory marks (PIE / PIH) start fading.
The dark spots, redness, and hyperpigmentation that stood out three months ago are visibly receding.
This is when visible scar reduction becomes most apparent — the result of consistent nightly use without downtime.
Many customers say they think less about lighting and angles, and more about simply getting on with their day.
Collagen support continues to build around the 6–9 month mark. New breakouts may heal with less visible scarring.
One year in, most customers describe smoother, more even-looking skin — the result of a simple routine repeated every night.
