Public cases and clinical summaries

These are paraphrased summaries of public forum posts or clinical reports. They are included to show recurring patterns, with source links for context.

Public forum

Home gel use followed by cuticle itching, swelling, and nail lifting

Background
A home user described several months of DIY gel and stamping products, with concern about accidental contact with uncured gel.
Product
The thread mentions Beetles gel polish and other at-home gel products; the exact allergen was not patch-tested in the post.
Symptoms
The public account describes itchy bumps around the cuticle, then redness, swelling, severe itching, nail lifting, and peeling.
How it was identified
The user connected the timing to repeated gel exposure and uncured product contact. The post is a public experience, not a medical diagnosis.
Current approach
The commenter reported switching back to regular lacquer and avoiding gel systems after the reaction.
Public forum

Reaction after builder gel despite switching to HEMA-free products

Background
A user reported an earlier reaction after a rubber base product, then switched to HEMA-free products and later builder gel.
Product
The post mentions Neonail Rubber Base, HEMA-free products, and Didier Lab builder gel.
Symptoms
The public account describes itching, blisters, skin peeling, and touch sensitivity after suspected under-curing.
How it was identified
The user suspected a broken or inadequate lamp caused under-cured product exposure. HEMA-free labels did not eliminate all acrylate risk.
Current approach
The post discusses removing the product and pausing nail enhancements while the skin and nails recover.
Clinical report

Clinical report: HEMA-free gel polish still caused allergic contact dermatitis

Background
A case report described allergic contact dermatitis that mimicked swelling of the lips and eyelids after use of a vegan product marketed as HEMA-free.
Product
Vegan HEMA-free gel nail polish containing other acrylates and isocyanates.
Symptoms
The report focused on facial and eyelid/lip dermatitis rather than only skin around the nails.
How it was identified
The case was evaluated clinically and linked to acrylates and isocyanates in the gel product, showing that HEMA-free does not mean acrylate-free.
Current approach
The case supports patch testing and avoiding the confirmed allergen family rather than relying only on front-label claims.

Patterns these stories show

Symptoms can start after repeated exposure

Several reports describe normal early use followed by itching, swelling, peeling, or nail lifting after later applications.

HEMA-free is not acrylate-free

Some users and clinical reports still involve reactions to other acrylates, methacrylates, isocyanates, or nail glue ingredients.

Undercuring raises exposure risk

Uncured or under-cured gel leaves more reactive monomer available to touch skin during application, wear, or removal.
