What are Korean nail gels?

Gel nail coatings are UV/LED-curable systems that contain oligomers/monomers (e.g., acrylates), pigments, and photoinitiators.
When exposed to UV or LED light, the photoinitiators trigger polymerization, forming a cross-linked film that is durable and glossy.
Korean gel systems are known for high pigment density, smooth self-leveling application, and consistent curing behavior when used according to the manufacturer’s instructions.

Responsible use and basic safety

• Skin contact: Avoid contact of uncured gel with skin and cuticles. Wipe any excess before curing to reduce the risk of irritation or sensitization.
• Thin layers and full cure: Apply thin coats and cure each layer for the time specified for your lamp type (UV vs. LED). Under-curing may leave residual monomer.
• Ventilation and hygiene: Work in a well-ventilated area, keep tools clean, and follow good salon hygiene practices.
• Removal: Use manufacturer-recommended soak-off or file-off procedures. Do not peel cured product from the nail plate.
• Sensitive users: Individuals with a history of acrylate allergy or hand dermatitis should consider patch testing under professional guidance and choose products accordingly (e.g., low-sensitizer, HEMA-free options).
• Children: The nail plate and periungual skin in children are more delicate; avoid exposure to uncured materials and professional-strength systems. When in doubt, do not apply.

Regulatory context (EU)

In the European Union, nail gels are cosmetic products and must comply with Regulation (EC) No 1223/2009.
Key elements include: an EU-based Responsible Person, a Product Information File (with Cosmetic Product Safety Report), ingredient labeling (INCI), notified formulas in the CPNP, and adherence to any restrictions set in the Regulation’s Annexes.
Professional users should remain informed about updates that affect monomers and photoinitiators used in UV/LED systems.

Who is this for?

The content is written for trained nail technicians who need concise, technical guidance, and for informed consumers who want reliable, non-promotional information before using gel systems at home or in a salon.

Always cross-check individual product instructions (lamp type, cure times, removal method) and comply with local professional practice requirements.
