Is the L30 Not that shy nail polish safe for people with sensitive nails or skin?

The polish contains strong solvents such as butyl acetate, ethyl acetate and isopropyl alcohol, as well as phthalic and trimellitic anhydrides and styrene, which can be irritating to very sensitive skin or nail beds; a patch test on a small nail area is recommended before full application.

What function does nitrocellulose serve in this nail polish?

Nitrocellulose acts as the primary film-former, creating a flexible, durable coating that dries quickly and helps the pigment adhere firmly to the nail surface for long-lasting color.

How often should this nail polish be applied, and does it contain any controversial chemicals?

Typical use involves applying two thin coats, allowing each layer to dry before a possible topcoat; the formula includes chemicals such as phthalic anhydride, trimellitic anhydride, and styrene, which are sometimes flagged as controversial due to potential sensitisation, so application should be done in a well-ventilated space and discontinued if irritation occurs.
