The duration required to harden gel nail coatings under a UV or LED lamp is a critical factor in achieving a long-lasting and chip-resistant manicure. Insufficient exposure to the light source can result in a tacky or uncured finish, compromising the integrity of the coating and potentially leading to premature peeling. For instance, a standard gel polish application might necessitate a 30-second exposure under an LED lamp or two minutes under a UV lamp for each layer.
Proper hardening of gel polish is essential for its durability and aesthetic appeal. A fully hardened coating provides a smooth, glossy finish and resists chipping and scratching. Furthermore, inadequate exposure can lead to allergic reactions in some individuals due to the presence of uncured monomers. Historically, UV lamps were the primary method for hardening gel coatings; however, LED lamps have become increasingly popular due to their faster hardening times and longer lifespan.
