Last week I explained the reasons for K-Beauty's rise in the global skincare market - you can read this post about the rise of K-Beauty here.

Today I'm going to show you what I've learned from Korean skincare over the years using their products. To be quite honest, I don't remember exactly how I started using Korean products.

But what I do know is that it all started with my curiosity to try new products. I must have bought a product, liked it a lot, and one thing led to another until I got deeper into the subject. Not to mention the fact that I have a peculiar relationship with my skin — I talk more about this in this personal post here.

I've learned a lot about how to take care of my skin since I got to know Korean skincare, I've been surprised by some of the practices and I've changed my mind in some respects. In this post, I'll tell you the 5 lessons that were a game changer.

Just an important reminder: the big secret to healthy skin is holistic health management. It's not just using skincare products that will change your skin's health. It's a complex set of factors that complement each other. I want to make it clear that it's not just Korean products that have improved my skin. In this post, I focus only on topical skin care!

1. Moisturizing

The first thing I learned from the Korean skincare philosophy is that moisturizing can never be overdone —especially as skin ages.

I used to think that if I have oily skin (very oily and acne-prone, by the way), moisturizing would only make my skin produce more sebum and therefore more pimples.

Nooo. I was completely wrong!

When I finally started using moisturizer, that's when my skin started producing less sebum. This is because moisturizing regulates oil production, bringing the skin into a state of balance.

The skin is always trying to maintain a balance between water (hydration) and oil (sebum). When it notices that it is dehydrated (lack of water), it goes into a state of alert and tries to compensate by producing more oil — as if to say:

"I'm too dry, I'll produce more oil to form a barrier and hold on to what's left of the moisture."

By applying a light moisturizer, you restore hydration and help the skin return to balance. The body then understands that it no longer needs to compensate with excess oil. The result? Sebum production decreases — naturally.

And the same principle applies to dry skin — but instead of producing more sebum to compensate, dry skin reacts with flaking, pulling and inflammation. Therefore, to achieve balance in genetically dry skin, it is necessary to use a denser moisturizer, capable of deeply nourishing and protecting.

Moisturizing the skin (oily, combination or dry) is a gesture of collaboration with the body's homeostasis system. Instead of fighting oiliness, dryness or pimples, you show the skin that it is safe and balanced — and it responds with vitality and resilience.

So hydration is essential.

2. The Sequence of Product Application Matters (a lot!)

Here things get more technical — but not to make things more complicated (they already are! haha) — it's to give results. The sequence in which you apply the products matters because of the skin's ability to absorb different types of formulas.

To put it simply: the easiest way to know which product to apply first is to look at the texture. More liquid textures are absorbed more quickly by the skin (such as tonics and essences) — start there. If you apply something too thick first (like a cream), it will create a barrier and prevent the other products from penetrating properly, losing their effectiveness. Makes sense, right?

Therefore, to maximize results and avoid waste, you need to follow the right order to ensure that nothing cancels each other out and that each active ingredient works where it needs to — without overloading or blocking the skin.

3. Double cleansing

Using an oil-based cleanser and then a water-based one changes the game — especially if you use sunscreen and make-up. Micellar water or make-up remover don't clean the skin enough.

Double cleansing prepares the skin for more effective absorption of skincare. This doesn't mean that you have to cleanse your skin all the time — that could even have an undesirable effect. But, without no doubt, at the end of the day is when your skin most needs a complete and effective cleanse.

4. Sun Serum

If you're not much of a skincare person, have never taken care of your skin or don't know anything about it, but are interested, here's the biggest and most important lesson: if you want to take care of your skin, but don't have the time, baggage or money to spend on it — just use a good sunscreen.

Sunscreen is the most important product in any skincare routine. Sun, rain, indoors, outdoors — it doesn't matter.

But years ago I thought that any sunscreen would do the trick.

Wrong. Another thing I had no idea about.

Sunscreens are different and there is a lot of controversy about them. The subject is extensive. So, for the purpose of this post, I'll simplify.

Korean sunscreens have different formulations to those we're used to in the West. In short? They're superior. Most, for example, don't contain hormone-disrupting ingredients (which are very common in the West) or fragrances.

Sun serums are multifunctional, have high protection, are comfortable to use, the variety is almost endless and the exceptional quality — combined with low prices — is the complete package.

5. Give Products Time to Show Results

Everything worthwhile takes time — and that couldn't be any different with skincare. Consistency and patience are essential. It's a long-term game. And I'm well aware of that.

Don't expect quick and dramatic results. It takes time to balance health and strengthen skin resilience. Results last when they are built up gently and consistently.

Final Thoughts

These are the 5 lessons I learned when I was accidentally introduced to the Korean skincare philosophy.

And, of course, these lessons are universal — they don't depend on the brand or the origin of the products. But in my experience, it was through K-beauty that they finally made sense to me and began to really work. They're simple lessons, but they're so simple that we end up forgetting them.

Note: everything I share here comes from my personal experience and curiosity. I'm not a dermatologist, so use this information as a starting point — and never as a substitute for professional advice.
