Gel manicures are a beauty favorite because they’re glossy, long-lasting, and dry quickly. But when it comes to skin and nail health, there’s more to consider than just the finished look. Our dermatologists weigh in on two main aspects of gel manicures—UV/LED curing lamps and the chemicals in the gel polish itself—to help you make informed decisions about your nails.
UV/LED Lamps: What the Evidence Shows
To cure gel polish, salons use UV or LED lamps that emit mainly UVA radiation—the same type of ultraviolet light linked to skin aging and DNA damage. Recent studies have shown that repeated exposure to these lamps in laboratory settings can cause DNA changes in skin cells similar to those caused by sun exposure. However, real-world risk in humans is not fully established.
Experts stress that cumulative UV exposure—whether from the sun or nail lamps—may add up over years, especially if gel manicures are done frequently (every few weeks). While the overall cancer risk from lamps alone is considered low, it’s still prudent to protect your hands, especially if you have fair skin or a personal or family history of skin cancer.
Gel Polish Chemistry: Allergies, Formulas, and Nail Damage
In addition to UV exposure, dermatologists are paying closer attention to the chemicals in gel polish. Many formulas contain acrylates and methacrylates, which can trigger allergic contact dermatitis with repeated exposure. Symptoms include redness, itching, swelling around the nails, nail lifting, or rashes on nearby skin.
Recently, gel polish safety made headlines after the European Union banned the use of TPO (trimethylbenzoyl diphenylphosphine oxide), a photoinitiator often used to help gel polish cure under UV light. While this restriction does not currently apply in the U.S., it has raised awareness about the importance of moderation and product quality.
Gel manicures can also affect nail health when they’re applied or removed improperly. Repeated soaking, scraping, or peeling can weaken the nail plate, leading to thinning, peeling, and brittleness over time.
Practical Tips from Dermatologists
If you enjoy gel manicures but want to reduce your risk of adverse reactions:
- Apply broad-spectrum sunscreen (SPF 30+) to the backs of your hands approximately 15 to 30 minutes before nail curing—avoiding the nail plate itself for best polish adhesion.
- Consider wearing UV-protective fingerless gloves that expose only the nails.
- Space out your appointments to reduce cumulative UV exposure.
- Consider reserving gel manicures for special occasions.
- Avoid picking or peeling off gel polish; always have it professionally removed, or follow proper at-home removal techniques with appropriate tools.
- Research salons and their gel manicures carefully, looking for those that avoid gel polish with known allergens and potentially concerning substances in their formulas.
Gel manicures can be safe when done occasionally and with simple precautions—but they’re not risk-free. UVA exposure from lamps and potential chemical sensitivities make it important to protect your skin and nails, especially if you get gel manicures often.
