photoprotection is the set of measures used to reduce skin and tissue injury from ultraviolet (UV) radiation and other light exposures. It commonly includes behavioral strategies (shade, timing), protective clothing, and topical products such as sunscreen. In cosmetic and plastic care, photoprotection is used before and after procedures to support even healing and help reduce pigment changes. It is relevant in both aesthetic and reconstructive settings, including scar care and prevention of photoaging.

pH-balanced describes a product or solution formulated to have an acidity level intended to be compatible with a specific tissue, most often skin. In cosmetic and plastic surgery settings, it commonly refers to cleansers, wound-care products, and peri-procedural skincare. It may be used in both cosmetic care (appearance-focused) and reconstructive care (function- and healing-focused). “Balanced” does not mean “one pH fits all”; it typically means matched to the target area and use.

comedogenicity describes how likely a substance is to contribute to clogged pores (comedones). It is most often discussed for skincare, cosmetics, sunscreens, ointments, and hair products. In clinical settings, it helps guide product selection for acne-prone skin and post-procedure skin care. It can be relevant in both cosmetic and reconstructive care because topical products are commonly used before and after procedures.
