Allergy considerations

  • HEMA, HPMA, Di-HEMA TMHDC, and other methacrylates can cause allergic contact dermatitis.
  • HEMA-sensitive users may also react to related methacrylates such as HPMA or Di-HEMA TMHDC.
  • Watch for redness, itching, swelling, skin peeling, or blisters around the nail fold.

UV exposure

  • Builder gel cures under UV/LED lamps; product-specific wavelength is usually not disclosed on listings.
  • Use the lamp and cure time specified by the brand, typically 30-90 seconds per layer.
  • Mitigation: apply SPF 30+ to hands before curing or use UV-protective fingerless gloves.

Regulatory note: In the United States, cosmetics are regulated by FDA but are generally not pre-approved before sale. Ingredient disclosure and recall checks are therefore part of the safety review.
