LUCA™ is one of the best UVA/UVB sunscreens available in the United States because the formulation contains Polycrylene®, a novel Avobenzone stabilizer and strengthener. Avobenzone provides great UVA protection, but without the addition of Polycrylene®, it begins to breakdown after 10 minutes in intense sunlight. In addition to excellent UVB coverage rated by familiar SPF ratings, LUCA™ is the only product in the United States to voluntarily place a critical wavelength value on the label showing their level of UVA protection.

Science of Encapsulation
LUCA Sunscreen is introducing a new product, Critical Wavelength to the sunscreen market. This is a unique product in that it is a water based spray on zinc formulation, and it utilizes encapsulation technology to encase the sunscreen active ingredients within a beeswax type material.
Encapsulation of active materials achieves a couple of things:
- One achieves a more uniform application with encapsulation, this allows for lower levels of active ingredients for the same SPF or Critical Wavelength rating. Encapsulation produces active ingredient particles of a more uniform size, allowing for not only a more even spread, but in the case of zinc, optimizing the size for the exact part of the UVA/UVB range that one wants to block.
- Encapsulation also decreases the incidence of skin irritation. There is always someone that is going to be irritated by a particular product. The goal behind a product designed for sensitive skin is to minimize the number of people who might have a problem. Fragrances, natural oils, and preservatives are among the leading causes skin irritation, as are sun screen active ingredients. Encapsulation reduces the incidence of skin irritation, because not only are the active ingredient levels lower, but they are encased in beeswax, as opposed to being in direct contact with the skin surface.
One might notice that the critical wavelength measurement of Critical Wavelength Spray on Sport SPF 30 formulation is 372nm as opposed to other LUCA Sunscreen products with critical wavelength values of 383nm. This is the nature of zinc oxide. Critical wavelength values peak in the early 370nm range for zinc formulations, as opposed to formulations containing avobenzone that allow for higher critical wavelength values. The American Academy of Dermatology considers any product with critical wavelength over 370nm to provide excellent UVA protection. In designing a sports formula, zinc oxide was preferable, as it produced a product that was more sweat proof.
Critical Wavelength Spray on Sport took over 2 years to develop. In designing a spray zinc there are challenges. The zinc particles need to be of an optimum size for UVA protection (400-500nm) and in concentration below 5% to keep the particles in suspension. Encapsulation allows each of these goals to be achieved.
Critical Wavelength Sport on Sport is 68% water, contains no alcohol or oil, and represents a milestone in sunscreen development.
