Chemical peels work by applying an acidic solution to the skin that disrupts cell adhesion at a controlled depth, causing the upper layers to exfoliate. The body responds with accelerated cell turnover and, for medium and deep peels, new collagen formation. The depth of penetration — controlled by acid type, concentration, application technique, and number of passes — determines both the result and the recovery.
Korean dermatology clinics use peels as part of a broader protocol rather than as standalone treatments. A pico laser session followed two weeks later by a medium-depth peel targets different skin structures than either modality alone.
Peel depths and what they treat
| Peel type | Depth | Agents used | Best for | Downtime |
|---|---|---|---|---|
| Superficial | Epidermis only | AHA (glycolic, lactic), BHA (salicylic), low TCA (10–15%) | Glow, mild congestion, very mild texture | None to 1–2 days mild dryness |
| Yellow peel (Enerpeel) | Papillary dermis (biorevitalising) | TCA + H2O2 + retinoic acid or kojic acid | Brightening, mild resurfacing, collagen stimulation | Minimal — mild redness 1–2 days |
| Medium (Jessner's) | Papillary to upper reticular dermis | Resorcinol + salicylic acid + lactic acid | Pigmentation, moderate sun damage, mild acne scars | 5–7 days peeling |
| Medium (TCA 20–35%) | Papillary to reticular dermis | Trichloroacetic acid | Sun damage, wrinkles, acne scars, melasma | 5–7 days active peeling + redness |
| Deep (phenol / Baker-Gordon) | Reticular dermis | Phenol 88%, Baker-Gordon formula | Severe photoageing, deep wrinkles, perioral lines | 10–14 days; full recovery 4–6 weeks |

The yellow peel: Korea’s routine skin refresh
The yellow peel — most commonly Enerpeel (AB Medica) or PRX-T33 (WiQo) — is a TCA-based product combined with hydrogen peroxide that neutralises the surface frosting reaction, allowing the TCA to penetrate the dermis without removing the epidermis. The addition of kojic acid (Enerpeel) or retinoic acid (PRX-T33) triggers fibroblast activity in the dermis.
The result: dermal collagen stimulation without the surface damage and peeling of a standard TCA peel. Skin appears brighter and more hydrated from the next day; mild redness resolves in 24–48 hours. Korean clinics use it as a monthly brightening protocol and as a post-laser skin quality enhancer.
How Korean clinics combine peels with laser
A common protocol for hyperpigmentation:
- Pico laser session (week 1): Targets epidermal and dermal pigment via photoacoustic effect
- Yellow peel or superficial TCA (week 2–3): Accelerates shedding of disrupted pigment; stimulates new cell turnover
- Pico toning (month 2): Low-fluence maintenance to prevent pigment recurrence
A common protocol for acne-prone, textured skin:
- Salicylic acid peel series (4–6 sessions, every 2 weeks): Anti-comedonal, anti-inflammatory
- Fractional CO2 or RF microneedling (after acne is controlled): Scar remodelling
- Maintenance AHA peel (monthly): Prevents recurrence
What is the yellow peel and why is it popular in Korea?
The yellow peel (commonly Enerpeel or PRX-T33) combines trichloroacetic acid (TCA) with hydrogen peroxide and kojic acid or retinoic acid. The combination creates a biorevitalising effect in the dermis without the significant surface peeling of a standard TCA peel — making it a 'no-downtime' or low-downtime option. Korean dermatologists use it widely for brightening, mild textural improvement, and as a complement to laser protocols.
Is a chemical peel safe for darker skin tones?
Superficial peels (AHA, BHA, low-concentration TCA) are generally safe for all skin tones when performed by an experienced practitioner. Medium and deep peels carry higher risk of post-inflammatory hyperpigmentation (PIH) in Fitzpatrick III–VI skin. Korean dermatologists see a high proportion of Asian skin types and are experienced in adapting concentration and pH to minimise PIH risk — but it is important to confirm the peel type and concentration before proceeding.
How do peels fit into a Korean treatment trip?
Superficial peels and yellow peels can be done 1–2 days before flying home — minimal downtime, no flying restriction. Medium-depth TCA peels (20–35%) are best scheduled at least 5–7 days before departure to allow the active peeling phase to complete. Deep phenol peels require extended stay (10–14 days) and are not appropriate for a short trip. Discuss your departure date when booking.
