Sunscreen lotion is a topical product designed to protect the skin from the harmful effects of ultraviolet (UV) radiation from the sun. It is an essential part of daily skincare to prevent sunburn, premature aging, and skin cancer. Here’s a detailed description of sunscreen lotion:

Features:
SPF (Sun Protection Factor): Indicates the level of protection against UVB rays, which are responsible for sunburn. SPF values typically range from 15 to 50+.
Broad-Spectrum Protection: Many sunscreens offer protection against both UVA and UVB rays. UVA rays penetrate deeper into the skin and contribute to aging and skin cancer.
Formulation: Available in various formulations including lotions, creams, gels, sprays, and sticks, catering to different skin types and preferences.
Water Resistance: Some sunscreens are formulated to be water-resistant for a certain period, typically 40 or 80 minutes, making them suitable for swimming or sweating.
Active Ingredients: Contains either chemical filters (like avobenzone, octinoxate) that absorb UV radiation, or physical/mineral filters (like zinc oxide, titanium dioxide) that reflect UV radiation.
