The Korean Skincare Routine I Tried for 90 Days — Here’s What Actually Happened

I want to be honest with you right from the start: I was a skincare skeptic. My entire routine for the better part of a decade consisted of splashing water on my face in the morning, maybe using whatever bar soap was in the shower, and calling it a day. My skin was… fine. Not great, not terrible. Just perpetually dull, occasionally breaking out around my chin, and starting to show those first fine lines around my eyes that made me do a double-take in the bathroom mirror.

Then my coworker Sarah walked into the office one Monday looking like she’d had some kind of divine intervention over the weekend. Her skin was luminous — and I don’t use that word lightly. When I asked what she’d done, she laughed and said she’d been doing a Korean skincare routine for about six months. She rattled off words like “double cleansing” and “essence” and “snail mucin,” and I remember thinking she sounded absolutely unhinged. But her skin didn’t lie. So I went home that night, fell down a three-hour rabbit hole of Reddit threads and YouTube tutorials, and decided I was going to commit to a full Korean skincare routine for 90 days. No shortcuts, no skipping steps, no excuses.

What followed was one of the most surprisingly transformative experiments I’ve ever done — and not just for my skin. Here’s the full, unfiltered account of what happened when a skincare minimalist went full K-beauty for three months.

Week One: The Learning Curve Was Steeper Than I Expected

Let me paint you a picture of my first evening with a 10-step Korean skincare routine. I had about a dozen products lined up on my bathroom counter, a printout of the correct order taped to my mirror, and absolutely no idea what I was doing. The whole process took me nearly 45 minutes that first night because I kept second-guessing which step came next and whether I was applying things correctly.

The routine I settled on, after way too much research, looked like this:

1. Oil cleanser (to remove sunscreen and makeup residue)
2. Water-based cleanser
3. Exfoliant (only twice a week)
4. Toner
5. Essence
6. Serum
7. Sheet mask (two to three times a week)
8. Eye cream
9. Moisturizer
10. Sunscreen (morning only)

I started with the COSRX snail mucin essence because it seemed to be the one product that absolutely everyone raved about. I’ll admit, the idea of putting snail secretion on my face made me gag a little. It has this slightly viscous, almost stringy texture that looks deeply unappealing in the bottle. But once I patted it onto my skin, it absorbed surprisingly well and left this subtle dewy finish that I didn’t hate.

The double cleansing was the biggest adjustment. I’d never used an oil cleanser before, and the sensation of massaging oil into my face felt counterintuitive — especially since I have combination skin that leans oily in the T-zone. But when I followed it with my water-based cleanser, my skin felt genuinely clean in a way it never had before. Not stripped or tight, just… clean. I could actually feel the difference, and that was enough to keep me going through those awkward first days.

By the end of week one, I’d gotten the routine down to about 15 minutes in the evening and 8 minutes in the morning. My skin hadn’t changed much yet, but I noticed it felt softer when I touched my cheeks. A small win, but I was clinging to any sign that this wasn’t a complete waste of time and money.

The Products That Earned Their Spot (and the Ones That Didn’t)

Over the 90 days, I went through a fair amount of trial and error. Some products became holy grails; others got quietly shuffled to the back of the cabinet. Let me break down what actually delivered results.

The winners:

• Snail mucin essence: I cannot overstate how much this product changed my skin’s texture. Within three weeks, the rough patches on my forehead smoothed out, and my skin had this plump, hydrated quality that I’d genuinely never experienced before. I used it morning and night without fail.
• Sunscreen: I know this sounds boring, but wearing proper SPF every single day — even when I wasn’t leaving the house — made a visible difference in the evenness of my skin tone by month two. I used a lightweight Korean sunscreen that didn’t leave a white cast or feel greasy under makeup.
• Oil cleanser: The double-cleanse method was a revelation. My pores around my nose, which had been visibly clogged for years, started looking noticeably clearer by week four.
• Moisturizer: I switched to the Laneige overnight sleeping mask about three weeks in, using it as my final step at night. Waking up with genuinely soft, bouncy skin became the norm rather than the exception.

The disappointments:

• Sheet masks: I wanted to love these so much. They’re the most iconic part of K-beauty, and they feel incredibly luxurious. But honestly? I didn’t notice a dramatic difference on the days I used them versus the days I didn’t. They were pleasant, sure, but for the cost and the time commitment, I eventually dropped them down to once a week.
• Multiple serums: I tried layering a vitamin C serum, a niacinamide serum, and a hyaluronic acid serum, and my skin basically revolted. Turns out, more isn’t always more. I scaled back to just one serum at a time and my skin thanked me for it.

The biggest lesson here was that Korean skincare isn’t really about using ten products. It’s about understanding your skin’s actual needs and building a routine around those needs. Some nights I did the full routine; other nights I pared it back to five steps because my skin was feeling fine and didn’t need the extra layers. That flexibility was something the online tutorials never really mentioned, but it ended up being crucial to sticking with the whole thing.

Month Two: When I Started Seeing Real Changes

The first month was mostly about building the habit and getting comfortable with the process. The real transformation started somewhere around week five, and it happened so gradually that I almost missed it.

I was brushing my teeth one morning when I caught a glimpse of my reflection and actually paused. My skin looked… different. Not in some dramatic, Instagram-filter kind of way, but in a subtle, hard-to-pinpoint way that made me lean closer to the mirror. The dullness that I’d accepted as just “my skin” was gone. There was a softness and a clarity that hadn’t been there before. The fine lines around my eyes hadn’t disappeared, but they looked less pronounced, like the skin around them was more hydrated and plump.

I’d been taking progress photos every two weeks (something I’d highly recommend if you try this), and when I compared my week-six photo to my day-one photo, the difference was striking. My skin tone was more even, the redness around my nose had calmed down significantly, and the texture on my forehead — those tiny bumps that weren’t quite pimples but never fully went away — had smoothed out almost entirely.

The Beauty of Joseon propolis and niacinamide serum deserves special credit here. I introduced it at the start of month two, and within two weeks, my skin had a glow that I can only describe as “lit from within.” I know that sounds like marketing nonsense, but I genuinely don’t have a better way to describe it. The niacinamide helped with the redness and uneven tone, while the propolis seemed to add this layer of luminosity that even my foundation couldn’t replicate.

People started commenting. My partner said something about my skin looking “healthy.” A friend asked if I’d changed my diet. My mom, who has never once complimented my appearance without immediately following it up with constructive criticism, told me I looked well-rested. That might not sound like much, but coming from her, it was basically a standing ovation.

I was also sleeping better, and I think the routine had something to do with that. Having a structured evening ritual — the cleansing, the patting, the waiting between layers — forced me to slow down for 15 minutes every night. It became almost meditative. Instead of scrolling my phone until I passed out, I was standing in my bathroom, gently pressing essence into my skin, and something about that repetitive, quiet process helped my brain shift into sleep mode.

The Unexpected Costs (Financial and Otherwise)

Let’s talk about money, because nobody seems to want to address this honestly. Korean skincare has a reputation for being affordable, and compared to high-end Western brands, it generally is. But “affordable” is relative, and when you’re buying eight to ten products, those affordable price tags add up fast.

Here’s roughly what I spent over the 90 days:

Initial product haul: about $120. Replacement products (I went through the cleanser and toner faster than expected): about $45. Additional products I tried and didn’t keep: about $60. Total: roughly $225 for three months.

That’s $75 a month, or about $2.50 a day. Is that reasonable? I think it depends on your budget and your priorities. For me, it was more than I’d ever spent on skincare, but less than what I’d been spending on coffee. When I framed it that way, it felt manageable. But I also want to acknowledge that it’s a genuine expense, and anyone who tells you that K-beauty is cheap isn’t being fully honest.

The time cost was significant too. Even once I had the routine down, I was spending about 20 to 25 minutes a day on skincare — roughly 12 minutes at night and 8 in the morning. Over 90 days, that’s close to 37 hours. More than a full work week spent patting things into my face. Was it worth it? I think so, but it’s a real commitment, and there were mornings when I was running late and deeply resented the sunscreen step.

There’s also the mental load of keeping track of which products to use when, what order to apply them in, which ones you shouldn’t mix, when to reorder before you run out. I kept a simple spreadsheet tracking my routine and when I opened new products, and honestly, without that, I would have lost the plot by week three. Korean skincare requires a level of organization that my bar-soap-and-water past self could never have imagined.

The COSRX low pH morning gel cleanser became a staple I repurchased twice during the experiment. At its price point, it was genuinely one of the best values in the entire routine — gentle enough for daily use, effective enough that my skin felt properly clean without that awful tight sensation, and the tube lasted a solid five to six weeks with daily use.

What My Skin Looked Like at Day 90

By the end of the 90 days, here’s an honest inventory of what changed and what didn’t.

What improved:

• Texture: This was the most dramatic change. My skin went from slightly rough and bumpy to genuinely smooth. Running my fingers across my cheeks and forehead, there were no rough patches, no tiny bumps, no flaky spots. This alone made the entire experiment worth it.
• Hydration: My skin stopped feeling tight after washing, stopped flaking around my nose in winter, and developed this supple quality that I’d always associated with people who just naturally had “good skin.”
• Tone evenness: The redness around my nose and the slight discoloration on my cheeks both faded noticeably. My skin wasn’t perfectly uniform — that’s not realistic — but it was significantly more even.
• Glow: I hate using that word because it’s been co-opted by every beauty brand on the planet, but there’s no better term. My skin had a natural luminosity that it had never had before. I started wearing less foundation because my bare skin actually looked decent.
• Breakouts: My chin breakouts, which used to pop up like clockwork every few weeks, reduced to almost nothing. I had maybe two small pimples in the entire 90 days, compared to my usual four or five per month.

What didn’t change:

• Fine lines: They looked slightly better due to improved hydration, but they were still there. Anyone who tells you skincare can erase wrinkles is lying. It can soften them, but it can’t reverse time.
• Pore size: My pores looked cleaner, but they weren’t smaller. Pore size is largely genetic, and no amount of toner or serum is going to change that fundamental reality.
• Dark circles: Still there. Still hereditary. Still unbothered by my expensive eye cream. I’ve made my peace with this.

I took a final comparison photo on day 90 and put it next to my day-one photo, and the difference was undeniable. Not life-altering, not unrecognizable, but clearly and meaningfully better. My skin looked healthier, more hydrated, and more alive. If someone had shown me that photo three months earlier and said, “This is what your skin could look like,” I would have signed up immediately.

Would I Do It Again? Here’s My Honest Take

Now that I’m past the 90-day mark, I’ve had some time to reflect on the whole experience, and my feelings are genuinely mixed — which I think is more useful to you than a straightforward “yes, do it” or “no, don’t bother.”

The results were real. My skin is objectively better than it was three months ago. People notice. I notice. I feel more comfortable going without makeup. I catch myself in mirrors and feel a little burst of satisfaction instead of that vague, low-grade dissatisfaction I’d carried around for years. Those aren’t small things.

But the full 10-step routine? I’ve already scaled it back. In the weeks since the experiment ended, I’ve settled into a streamlined version — about six steps in the evening and four in the morning. I kept the double cleanse, the essence, one serum, moisturizer, and sunscreen. I dropped the separate toner, the eye cream (which I never felt did much), and the twice-weekly sheet masks. My skin has maintained its improvements on this simplified routine, which tells me that a few really good products, used consistently, matter more than hitting some arbitrary number of steps.

The Beauty of Joseon sunscreen is the one product I will never stop using. Before this experiment, I was the person who only wore sunscreen at the beach. Now I understand, on a visceral level, why dermatologists beg people to wear it daily. The difference in my skin’s tone and texture since I started wearing SPF every single day has been the single most impactful change in my entire routine. If you take nothing else from this article, take that: wear sunscreen every day. It doesn’t have to be expensive or complicated. Just do it.

Would I recommend trying a Korean skincare routine? Yes, but with caveats. Start simple. You don’t need ten products on day one. Pick up a good cleanser, a hydrating essence, a moisturizer, and a sunscreen. Use those consistently for a month before adding anything else. Pay attention to how your skin responds, and let that guide your next steps rather than following someone else’s routine blindly.

The most important thing I learned in 90 days wasn’t which products to buy or what order to apply them in. It was that taking care of your skin is really just a form of taking care of yourself — and that showing up for that small act of self-maintenance every day has ripple effects you don’t expect.

My skin is better. My evenings are calmer. My relationship with my own reflection has shifted from avoidance to something approaching appreciation. For a three-month experiment that started as idle curiosity in my office kitchen, I’d call that a pretty remarkable outcome.

If you’re on the fence, give it a try. Start small, be patient, and take those progress photos. You might surprise yourself.
