The correct spelling of the commonly used term for lotion used to protect against the sun's rays is "sun cream", pronounced /sʌn kriːm/. The first part of the word "sun" is pronounced with the vowel sound /ʌ/, like "uh" in "hug". The second part, "cream", is pronounced with the long vowel sound /i:/, like "ee" in "tree". Together, the word is pronounced with equal emphasis on both syllables, creating a two-syllable word with a short and long vowel sound.
Sun cream, also known as sunscreen or sunblock, refers to a lotion, gel, or spray specifically formulated to protect the skin from the harmful effects of the sun's ultraviolet (UV) rays. It acts as a protective barrier that helps to prevent sunburn, premature aging, and potential damage to the skin, including the risk of skin cancer.
Sun cream typically contains active ingredients known as sunscreens, which effectively absorb or reflect UV rays to reduce their penetration into the skin. These active compounds fall into two categories: chemical sunscreens and physical sunscreens. Chemical sunscreens, such as avobenzone and octinoxate, work by absorbing UV rays and converting them into heat, while physical sunscreens, such as zinc oxide and titanium dioxide, act as a shield to physically block UV rays from reaching the skin.
To use sun cream, it is advised to apply a generous amount to all exposed areas of the body before heading outdoors, at least 15 to 30 minutes before sun exposure. Reapplication is recommended every two hours, or more frequently if swimming or sweating excessively. Sunscreens often come in various SPF (Sun Protection Factor) levels, which indicate the level of protection they provide against UVB rays, the main cause of sunburn.
In conclusion, sun cream is a protective product designed to shield the skin from the potentially harmful effects of the sun's UV rays, reducing the risk of sunburn and long-term damage. Regular and proper use of sun cream is highly recommended, particularly when spending time outdoors, to maintain healthy skin and minimize the risk of skin-related health issues.
The etymology of the word "sun cream" is a combination of two roots: "sun" and "cream".
- Sun: The word "sun" originated from the Old English word "sunne", which is derived from the Proto-Germanic word "sunnon". It has cognates in other Germanic languages, such as German "Sonne" and Dutch "zon". Ultimately, the term can be traced back to the Proto-Indo-European root *sóh₂w̥ (sun).
- Cream: The word "cream" comes from the Old French word "crème", which was derived from the Late Latin word "crema". This Latin term can be traced back to the Proto-Indo-European root *krēm- (to freeze, chill). The sense of "cream" meaning a cosmetic or medicinal preparation goes back to the 16th century.
