Gel nail polish and shellac applications have gained enormous popularity in recent years because they provide a flawless finish for weeks on end. However, their negative effects on nail health are often overlooked. At Virtuana Clinic, we have prepared this comprehensive guide to help you maintain the balance between an aesthetic appearance and healthy nails.
What Are Gel Polish and Shellac?
Gel nail polish is a specialist type of varnish that hardens by curing under UV or LED light. Shellac is a similar technology applied to the nail surface, offering durability of two to four weeks. Both methods last considerably longer than traditional nail polish; however, both the application and removal processes can cause specific damage to the nails.
How Gel and Shellac Polish Harm Your Nails
Nail Thinning and Weakening
Before gel polish is applied, the nail surface is filed and roughened. This process abrades the upper layers of the nail plate. With repeated applications, nails gradually become thinner, more brittle, and lose their flexibility. Prolonged acetone exposure during removal also accelerates this thinning.
Nail Dryness and Dehydration
Acetone-based solvents disrupt the nail's natural moisture balance. The nail plate and the surrounding tissue become dry, leading to a tendency towards cracking, peeling, and breaking. Damage to the cuticle area also leaves the nail root unprotected.
UV Radiation Exposure
The UV lamps used to cure gel polish expose the nails and the skin of the hands to ultraviolet radiation. Although the exposure time is short, cumulative effects can develop with regular, long-term use. The wider adoption of LED lamps as of 2026 has reduced this risk, but has not eliminated it entirely. It is advisable to apply broad-spectrum sunscreen to the hands before the procedure, or to use UV-protective fingerless gloves during curing.
Allergic Reactions
Acrylate and methacrylate compounds in gel nail polish can cause contact dermatitis. Symptoms such as itching, redness, blistering, and peeling around the nails may appear. This allergy can intensify over time and spread to the face and neck.
Nail Infections
Cracks or lifting points that develop beneath shellac create an ideal environment for fungal and bacterial infections. Particularly when the polish has partially lifted but has not been fully removed, moisture becomes trapped under the nail, increasing the risk of infection.
Recommendations for Protecting Nail Health
Rest Periods Between Applications
Rather than having gel polish applied back-to-back, it is recommended to allow a gap of at least two to three weeks between sessions. This time allows the nails to regain their natural moisture and structure.
Correct Removal Method
Never peel or scrape off gel polish. This action tears away the upper layers of the nail plate, causing serious damage. It should be removed professionally by soaking in acetone for an appropriate amount of time and then lifted off gently.
Moisturising and Nutrition
Nail oil containing vitamin E or a moisturiser should be applied regularly to the nails and cuticle area. Biotin supplementation may contribute to nail strengthening. A diet rich in protein, zinc, and iron also supports nail health.
Choosing a Reputable Salon
Professional salons that operate in compliance with hygiene standards, use quality products, and follow sterilisation protocols should be preferred. Sterilising shared tools and equipment minimises the risk of infection.
