12 steps, 90 minutes, $80–150. The complete first-timer’s guide to Korean glass skin facials.
You’ve heard about Korean facials. You’ve seen the glass skin results on Instagram. But you haven’t booked one because you don’t know what to expect — and that uncertainty is the biggest barrier. What do they do for 90 minutes? Will it hurt? Do you have to get naked? This is the step-by-step guide that removes every bit of anxiety so you can just book the appointment.
Most people who want to try a Korean facial never actually book one. The reason isn’t price — at $80–150, they’re cheaper than most Western facials. The reason is uncertainty. You don’t know the protocol, you don’t know the etiquette, and if the spa is in Koreatown, you might worry about a language barrier. All of these fears evaporate once you know what’s coming. So let’s walk through every single step.
Arrival and consultation: You’ll change into a robe or wrap. Your esthetician will examine your skin under a magnifying lamp, often with a skin analysis device that measures hydration, oil levels, and pore size. This isn’t a sales pitch — it determines which products they’ll use on you. Then the treatment begins.
Steps 1–2: Double cleanse. Oil cleanser first to dissolve sunscreen and sebum, then a gentle foam or gel cleanser. This is the same double-cleanse philosophy from K-beauty home routines, done professionally. Steps 3–4: Enzyme exfoliation and steam. A gentle enzyme peel removes dead skin cells without harsh scrubbing. Warm steam opens your pores and softens the skin for the next step.
Step 5: Extraction. Let’s be honest — this is the uncomfortable part. Your esthetician manually clears clogged pores and blackheads using a small tool. It’s not pleasant, but it’s thorough and worth it. Korean estheticians are trained extensively in extraction technique — they’re faster and more precise than most Western counterparts. The discomfort lasts 10–15 minutes.
Steps 6–8: Ampoule layering. This is where Korean facials diverge completely from Western ones. Instead of one serum, your esthetician layers 3–4 targeted ampoules — typically a hydrating essence, a brightening vitamin C ampoule, a calming centella serum, and a firming peptide concentrate. Each one is pressed into your skin with gentle massage techniques.
Steps 9–10: Sheet mask and LED therapy. A professional-grade sheet mask (far more potent than retail ones) sits on your face for 15–20 minutes while LED light therapy works overhead — red light for collagen, blue light for acne. This is the relaxation peak of the facial. Steps 11–12: Moisturizer and SPF finish. A rich cream seals everything in, and if it’s daytime, SPF goes on last. You leave glowing.
The differences are significant. Korean facials run 12 steps over 90 minutes for $80–150. Western facials typically offer 4–6 steps over 45–60 minutes for $150–400. Korean facials include multiple serum layers, LED therapy, and thorough extraction as standard. In Western spas, LED therapy and extraction are often add-ons that cost extra. The Korean approach treats the facial as a comprehensive skin treatment; the Western approach often feels more like expensive relaxation.
Stop retinol and all active exfoliants (AHA, BHA) for 3 days before your appointment. Don’t shave or wax the day of. Arrive with a clean face if possible, but don’t stress — the double cleanse handles everything. If you have specific concerns (acne, hyperpigmentation, sensitivity), mention them during the consultation so your esthetician can adjust products accordingly.
Your skin will be slightly pink and very hydrated. For the first 24 hours: use only a gentle cleanser, skip all actives (no retinol, no vitamin C, no AHA/BHA), and apply SPF religiously — your fresh skin is more sensitive to UV. After 24 hours, resume your normal routine. The glow typically lasts 5–7 days.
For general maintenance: once a month. This aligns with your skin’s natural 28-day cell turnover cycle. For specific concerns like acne scarring or hyperpigmentation: every 2 weeks for the first 2–3 months, then monthly. Most Korean facial clients in Seoul go monthly as part of their regular skincare routine — it’s maintenance, not a special occasion.
Your esthetician just spent 90 minutes layering hydration and actives into your skin. The at-home products below maintain those results between appointments. COSRX Snail 96 Mucin ($21) replaces the hydrating ampoule step. Illiyoon Ceramide Ato Cream ($16) locks in moisture the way the professional cream does. Beauty of Joseon Relief Sun ($10) protects the fresh, exfoliated skin that’s now more vulnerable to UV damage.
