You flew to Seoul, got the treatment, and now you're home. Or you finally found a US clinic that does Rejuran, and you're walking out with instructions you don't quite understand. Either way, the next two weeks determine how much of your result you actually keep.
Post-treatment aftercare is where most people lose 20 to 40 percent of what they paid for. They use the wrong cleanser on day two. They layer actives too soon. They skip sunscreen because their skin feels fragile. They go back to their normal routine on day five because the initial redness faded. Every one of these mistakes costs you treatment efficacy.
This protocol is the aftercare routine used in Seoul dermatology clinics, translated for at-home recovery. It's organized by treatment type and by phase — because Rejuran recovery is not the same as laser recovery, and both differ from chemical peel recovery.
Who This Protocol Is For
This protocol is for you if you've had — or are about to have — any of the following:
- Rejuran Healer, Rejuran HB, Rejuran I, or Rejuran S injections
- Juvelook or other PDLLA biostimulator injections
- Fractional CO2 laser, Fraxel, or similar ablative resurfacing
- Non-ablative laser toning (Q-switched, picosecond, Clarity II)
- Chemical peels (glycolic, salicylic, TCA, Jessner's)
- Microneedling or RF microneedling (Morpheus8, Secret RF)
- Hyaluronic acid dermal fillers
- Exosome therapy or PDRN infusions
- Ultherapy, Thermage, or other energy-based tightening
This protocol is not for you if:
- You're recovering from surgical procedures (rhinoplasty, blepharoplasty, facelift) — those require clinic-specific instructions that supersede general aftercare.
- You have active infection, open wounds, or unhealed biopsy sites.
- Your clinic gave you specific written aftercare instructions — follow theirs first. This guide is supplementary, not a replacement.
- You're under 18.
The Four Phases of Recovery
Every in-office treatment follows the same four-phase recovery arc, even though the durations differ by procedure. Understanding the phases makes the protocol make sense.
Phase 1: Acute (hours 0–24). Your skin is traumatized. The barrier is compromised, inflammation is peaking, and the skin's ability to tolerate even routine skincare is at its lowest. The rule: minimize everything. Water, gentle cleanser, barrier cream, sleep.
Phase 2: Calm (days 2–4). Inflammation begins to subside. The skin barrier starts rebuilding. This is when Korean clinics introduce centella-based soothing products and, for certain treatments, topical PDRN to accelerate cellular recovery. No actives, no exfoliants, no retinoids.
Phase 3: Rebuild (days 5–10). The skin is actively repairing. Fibroblasts are producing new collagen and elastin in response to the treatment. This is the window where peptides, PDRN, and barrier-supporting ingredients do their most important work. Still no retinoids, AHAs, or BHAs.
Phase 4: Maintenance (days 11–14+). Normal skin function resumes. You can gradually reintroduce actives and your regular routine. The treatment's long-term results are still building (collagen remodeling continues for 3–6 months), but your daily skincare returns to normal.
Rejuran Aftercare (All Variations)
Rejuran is polynucleotide injection — PDRN fragments placed in the dermis to stimulate fibroblast activity. The injection creates hundreds of micro-punctures plus localized inflammation as the PDRN is processed by cells. Recovery is fast but the aftercare affects results directly.
Phase 1: Day 0 (treatment day)
- Immediately after: Clinic applies cooling mask or ice pack. Redness and mild swelling are normal.
- Evening: Cleanse with lukewarm water and a fragrance-free gel cleanser (like Cerave Hydrating or Round Lab Soybean Cleanser). Pat dry, do not rub.
- Apply: A thin layer of ceramide barrier cream (Dr. Jart Ceramidin, Pith Blue Repair Hydro Soothing Cream, or equivalent). No toner, no serum, no sunscreen before bed.
- Do not: Apply makeup, use actives of any kind, exercise, drink alcohol, or sleep face-down.
Phase 2: Days 1–3
- Morning: Gentle cleanse → hydrating toner (no alcohol, no actives) → centella ampoule (Skin1004 Madagascar Centella, Purito Centella Green Level Buffet) → ceramide cream → mineral SPF 50.
- Evening: Gentle cleanse → hydrating toner → topical PDRN serum if available (VT Reedle Shot, Rejuran Healer Essential Essence, Sungboon Editor PDRN Ampoule) → ceramide cream.
- Continue to avoid: Retinoids, AHAs, BHAs, vitamin C, benzoyl peroxide, physical exfoliants, hot showers, sauna, intense exercise, alcohol.
- Expected: Small raised bumps at injection sites (these are normal and resolve in 24–72 hours). Mild pinpoint bruising in some patients.
Phase 3: Days 4–7
- Add: Peptide serum in the evening (Pith Core Rebuild Cream, Medicube Collagen Peptide, Medi-Peel Peptide 9). Peptides support fibroblast activity and amplify Rejuran's cellular effect.
- Continue: Centella, ceramide, and topical PDRN daily. Mineral SPF every morning.
- Optional: Gentle sheet masks (centella, heartleaf, or hyaluronic acid-based) 2–3 times this week.
Phase 4: Days 8–14
- Gradually reintroduce: Niacinamide, hyaluronic acid serums, fermented essences.
- Still avoid: Retinoids, AHAs, BHAs, vitamin C, physical exfoliants until day 10 minimum.
- Day 14: Normal routine can resume. Peak Rejuran results appear around weeks 4–6.
Juvelook and PDLLA Biostimulator Aftercare
Juvelook uses poly-D,L-lactic acid microparticles suspended in hyaluronic acid. Recovery is longer than Rejuran because the PDLLA creates a sustained controlled-inflammation response as fibroblasts build collagen around the microparticles. Mishandling the first week can cause visible nodules.
Phase 1: Day 0
- Critical rule: Massage injection areas firmly for 5 minutes, 5 times a day, for the first 5 days ("5-5-5 rule"). This prevents PDLLA particles from clumping and forming palpable nodules.
- Skincare: Same as Rejuran day 0 — gentle cleanse, ceramide cream only.
- Do not: Apply pressure to injection sites while sleeping (use a travel pillow if side-sleeping).
Phase 2: Days 1–5
- Continue the 5-5-5 massage rule. This is more important than any product you apply.
- Morning: Gentle cleanse → hydrating toner → centella ampoule → moisturizer → mineral SPF 50.
- Evening: Gentle cleanse → hydrating toner → barrier cream. Skip retinoids, actives, exfoliants.
- Avoid: Any facial massage other than the prescribed 5-5-5. Avoid facial rollers, gua sha, LED masks, any mechanical stimulation.
Phase 3: Days 6–14
- Add: Peptide serum and topical PDRN to support the collagen-building process that Juvelook is stimulating.
- Stop the 5-5-5 massage after day 5. Continuing longer can reduce treatment efficacy.
- Gradually reintroduce: Niacinamide from day 7, gentle exfoliants from day 10, retinoids from day 14.
Laser Aftercare (Fractional and Ablative)
Fractional CO2, Fraxel, and other ablative lasers create microscopic columns of thermal damage that trigger dramatic skin remodeling. Recovery is the most demanding of any common treatment — the skin barrier is severely compromised for days.
Phase 1: Days 0–3
- Cleanse: Only lukewarm water for the first 48 hours. No cleanser.
- Apply every 2–3 hours: A thick occlusive barrier cream. Vaseline, Aquaphor, or a ceramide occlusive (Dr. Jart Ceramidin Liquid Cream, La Roche-Posay Cicaplast Baume).
- Expect: Intense redness, swelling, crusting, itching, pinpoint bleeding. All normal.
- Critical: Do not pick. Do not exfoliate. Do not apply anything active.
Phase 2: Days 4–7
- Add gentle cleanser: Cerave Hydrating or similar. Use tepid water, not hot.
- Skin will flake and peel. Let it happen. Do not help the process.
- Apply: Centella ampoule + ceramide cream + occlusive on top, morning and evening.
- Mineral SPF 50 is mandatory from day 4 onward, even indoors near windows.
Phase 3: Days 8–14
- Add topical PDRN: Now safe to use. Accelerates recovery.
- Add peptide serum: Evening only.
- Gradually reduce occlusive: Skin is rebuilding its own barrier.
- Still avoid: All acids, retinoids, vitamin C, benzoyl peroxide.
Phase 4: Days 15–30
- Reintroduce actives very slowly. Start with low-strength niacinamide on day 15, then low-concentration vitamin C on day 21, then retinoids no earlier than day 30.
- Continue daily SPF indefinitely. Post-laser skin is photosensitive for months.
For non-ablative laser toning (Q-switched, picosecond lasers used for pigmentation), recovery is much faster — typically 48–72 hours of redness only, with full routine resuming at day 5–7.
Chemical Peel Aftercare
Chemical peels range from superficial (glycolic, lactic) to medium (Jessner's, 20–35% TCA) to deep (50%+ TCA, phenol). The aftercare protocol scales with peel depth. This protocol covers superficial and medium peels — deep peels require physician supervision.
Superficial Peel (glycolic, lactic, mandelic at clinic strengths)
- Day 0: No cleanser in the evening. Apply ceramide cream only. Expect redness and tightness.
- Days 1–3: Gentle cleanse, hydrating toner, centella, ceramide cream, mineral SPF. Mild flaking is normal.
- Days 4–7: Add peptide serum, topical PDRN. Continue mineral SPF.
- Resume actives: Day 5–7 (niacinamide first, retinoids day 10+).
Medium-Depth Peel (Jessner's, TCA 20–35%)
- Days 0–2: Water cleansing only. Thick barrier cream 3–4 times daily.
- Days 3–7: Visible peeling and frosting. Let it peel naturally. Do not pick.
- Days 8–14: New skin revealed. Continue gentle routine + centella + peptides + topical PDRN.
- Resume actives: Day 14–21.
Microneedling and RF Microneedling Aftercare
Microneedling creates thousands of vertical microchannels in the skin. The channels close within hours but the underlying wound-healing response continues for weeks. The first 72 hours are critical — anything applied topically can enter the dermis directly through open channels.
Day 0
- Nothing on the skin except prescribed post-treatment serum or saline for the first 24 hours. This is non-negotiable.
- Expect: Skin looks like a mild sunburn. Pinpoint bleeding resolves within hours.
Days 1–3
- Cleanse: Water only or extremely gentle cleanser.
- Apply: Centella ampoule + ceramide cream.
- Topical PDRN is especially effective during this window because microchannels enhance penetration. If you've ever wanted to maximize PDRN absorption, this is when.
- Avoid: All fragrances, essential oils, active ingredients.
Days 4–7
- Add: Peptide serum, hyaluronic acid, niacinamide.
- Sunscreen: Mineral SPF 50 daily.
- Resume: Normal cleansing and moisturizing routine.
Days 8–14
- Reintroduce: Gentle exfoliants (lactic acid, mandelic) from day 10. Retinoids from day 14.
- Avoid: High-concentration vitamin C, benzoyl peroxide, strong AHAs until day 14 minimum.
Dermal Filler and Neurotoxin Aftercare
Hyaluronic acid fillers (Juvederm, Restylane, Neuramis) and neurotoxins (Botox, Nabota, Innotox) have minimal skincare aftercare requirements but significant physical restrictions.
- Day 0: No skincare on injection sites for 4 hours. Ice for swelling. No massage except as prescribed by clinic.
- Days 1–3: Normal skincare can resume, but avoid: facial exercises, sleeping face-down (for filler), hot showers, sauna, strenuous exercise, alcohol.
- Days 4–14: Full routine OK. Continue to avoid aggressive facial massage for filler patients.
The Post-Treatment Recovery Kit
Regardless of which treatment you've had, this core kit covers 90 percent of aftercare needs:
- Gentle cleanser: Cerave Hydrating, Round Lab Soybean, La Roche-Posay Toleriane Dermo-Cleanser
- Alcohol-free hydrating toner: Pyunkang Yul Essence Toner, Round Lab Birch Juice Moisturizing Treatment
- Centella ampoule: Skin1004 Madagascar Centella, Purito Centella Green Level Buffet, Dr. Jart Cicapair
- Ceramide barrier cream: Dr. Jart Ceramidin, Pith Blue Repair Hydro Soothing Cream, La Roche-Posay Cicaplast Baume
- Topical PDRN serum: VT Reedle Shot 100/300, Rejuran Healer Essential Essence, Sungboon Editor PDRN Ampoule
- Peptide cream: Pith Core Rebuild Cream, Medi-Peel Peptide 9 Volume, Medicube Collagen Jelly Cream
- Mineral SPF 50: Beauty of Joseon Relief Sun Rice (uses chemical filters though — alternative: Round Lab Birch Juice Moisturizing Sun Cream for mineral)
- Occlusive (for laser/peel only): Aquaphor, Vaseline, or Cerave Healing Ointment
Total kit cost ranges from $150 at drugstore level to $350 at premium Korean clinical level. The premium kit is not twice as good — it's maybe 20 percent more effective, largely because of better PDRN and peptide products.
Common Mistakes That Cost You Results
1. Using your regular cleanser too soon. Foaming cleansers, micellar water with fragrance, cleansing oils — all too aggressive for post-treatment skin. Water or extremely gentle cleanser only, for as long as the protocol indicates.
2. Skipping sunscreen because the skin feels delicate. Post-treatment skin is photosensitive by a factor of 2–5x. UV exposure during recovery causes hyperpigmentation that can take months to fade — sometimes permanent.
3. Applying actives "just a little early." Retinoid two days before the protocol allows, or vitamin C "just for the antioxidant benefit" on day four — these small violations reduce treatment efficacy by 15–30 percent. The protocols have clinical reasons.
4. Picking at flakes or crusts. This causes scarring, hyperpigmentation, and barrier damage that undoes the treatment. Let the skin shed on its own timeline.
5. Returning to the gym too early. Sweat + heat + elevated blood flow = increased inflammation, bruising, and in filler cases, displacement of product. Follow clinic restrictions strictly.
6. Combining treatments too close together. Stacking Rejuran + laser + chemical peel in the same week is not "amplified results" — it's barrier catastrophe. Minimum 2-week spacing between different treatment types.
7. Not communicating changes to your clinic. If your skin reacts differently than expected — prolonged redness, unusual bruising, visible nodules, infection — contact your clinic immediately. Aftercare protocols assume normal healing. Abnormal healing requires medical response.
When to Contact Your Clinic
Call your clinic (not a dermatologist who didn't perform the procedure) if you experience:
- Severe pain beyond mild tenderness
- Fever, chills, or signs of systemic infection
- Spreading redness beyond the treatment area after day 3
- Pus, oozing, or crusting that smells
- Visible lumps or nodules that don't resolve with massage (filler/Juvelook)
- Vision changes (any filler procedure near the eyes)
- Asymmetry worsening beyond the expected timeline
- Severe swelling that doesn't improve by day 3
For non-urgent concerns — unusual texture, slow fading of redness, questions about products — email or message the clinic. Korean clinics typically respond within 24 hours in Korean and within 48 hours if responding in English.
The Long Game: Weeks 3–12
Most treatments don't show peak results until 4–12 weeks post-procedure. Collagen remodeling, cellular turnover, and pigmentation normalization all take weeks. This is where consistent maintenance skincare matters more than aftercare.
From week 3 onward:
- Continue topical PDRN 3–5 times a week. PDRN accelerates collagen remodeling, which is what determines long-term results from Rejuran, laser, microneedling, and Juvelook.
- Maintain peptide skincare evening routine. Peptides support ongoing fibroblast activity.
- Mineral SPF daily, indefinitely. Post-treatment skin remains photosensitive for 2–6 months.
- Reintroduce retinoids carefully at week 2–4 depending on treatment. Start 2x per week, build to nightly.
- Plan next treatment only when fully recovered. Rejuran series: 4 weeks apart. Laser: 6–8 weeks. Juvelook: 4 weeks for second session if needed, then 18–24 months.

Frequently Asked Questions
How long until I can wear makeup after Rejuran?
24 hours minimum. Use a fresh, gentle mineral foundation (Laura Mercier Tinted Moisturizer, Koh Gen Do, or similar) for the first week. Avoid heavy liquid foundations and color-correcting primers with alcohol.
Can I fly home the day after treatment?
Yes for most procedures. Hydrate aggressively, skip alcohol on the flight, and bring your aftercare products in your carry-on (most creams exceed liquid limits so buy travel sizes). Avoid red-eye flights after ablative laser — sleeping against a seat can disturb healing skin.
Is it safe to stack topical PDRN on top of what my clinic gave me?
Usually yes, but ask the clinic first. Most Korean clinics encourage topical PDRN and will often give you their dispensary version to use during recovery. If you're using an outside topical PDRN, bring the ingredient list to the clinic or email a photo for approval.
My skin is more reactive than before. Is this permanent?
Usually not. Post-treatment reactivity typically resolves within 4–8 weeks. If it persists beyond 12 weeks, you may have developed temporary sensitization — switch to an all-ceramide, fragrance-free routine for 4 weeks and reintroduce actives from scratch.
When can I get my next treatment?
Minimum spacing: Rejuran series 4 weeks apart (3–4 sessions), then maintenance every 6 months. Laser: 6–8 weeks between sessions. Juvelook: 4 weeks if splitting doses, then 18–24 months. Chemical peels: 4 weeks for superficial, 8–12 weeks for medium. Different treatment types: minimum 2 weeks between any two procedures.
