If I were starting over with Korean skincare, as an esthetician, here is what I would do:
I'd study the philosophy before the products.
One of the questions you'll inevitably get from clients is:
"Why Korean skincare?"
If your answer is simply, "Because the ingredients are better," you're missing one of the most meaningful parts of the conversation.
The ingredients certainly matter, but what drew me to Korean skincare wasn't a single ingredient or product. It was the philosophy behind it.
Korean skincare has historically viewed the skin as something to care for, not constantly correct. It emphasizes prevention over reaction, barrier health before aggressive correction, and understands that the skin is often a reflection of what's happening internally.
When you understand that philosophy, you stop repeating marketing language and start having authentic conversations with your clients. They can feel the difference.
I'd build my business around treatments—not products.
This is probably the advice I give most often.
When you're first getting started, it's tempting to buy a little bit of everything. Before long, your shelves are full of products you don't fully understand, and your treatment room starts to feel overwhelming.
Instead, I'd choose my treatments first....
Think about the clients you see most often. Are they struggling with acne? Aging? Pigmentation? Barrier damage? Purchase treatments around those concerns, then purchase the products that support those treatments.
I have found that this really simplifies everything.
Also, your retail recommendations become more intentional because they're simply an extension of the treatment your client just experienced—not random products you're hoping to sell.
I'd lean into a niche much sooner.
One of the biggest mistakes I see estheticians make is trying to be everything for everyone. In part because it feels safer. However, in reality, specialization builds trust.
When you're known for one or two things, referrals become easier, your marketing becomes more focused, and clients know exactly why they should book with you.
That's often what separates a busy esthetician from one who's constantly competing on price.
I'd learn the "why" behind ingredients.
The skincare industry moves quickly. There will always be another trending ingredient, viral product, or marketing claim.
The best way to avoid chasing trends is to understand the science behind them.
Learn what ingredients actually do. Understand how they interact with the skin.
Know why you're recommending something—not just what the brand says it does.
That confidence changes everything. Clients trust professionals who educate rather than persuade.
I'd become obsessed with consultations.
Some of the most important work you'll ever do happens before we even begin a service.
A great consultation isn't just about gathering information, it's about building trust.
I'd spend less time talking and more time listening. I'd make sure to ask thoughtful questions.
The better your consultation, the less your recommendations feel like selling and the more they feel like guidance. That's a completely different experience for your client.
I'd document everything.
Remember to take before-and-after photos (with the same lighting). Track each treatment and how you client responds. Keep records of homecare recommendations. All of these things are so important so that you can build on them the next time you see your client.
But I'd also document the human side: a wedding, vacation, job, etc. Those details matter! Not only do they help you become a better esthetician over time, but they also make your clients feel remembered which is one of the most powerful forms of hospitality we can offer.
I'd never forget that skin doesn't exist in isolation.
One of the greatest gifts Korean skincare gave me wasn't another ingredient.
It was a change in perspective. Sometimes the most valuable thing we can do isn't recommend another product—it's helping our client understand that there may be more influencing their skin than what they are or aren't doing with their daily skincare routine.
