Anti-aging is a valuable brand in science and business, and all these groups try to control the brand or benefit from it: In this way, the war for the meaning of "aging" for money, but especially for the perception of legitimacy. Anti-aging medication means early detection, prevention, and treatment of age-related diseases. This is very different from dealing with the aging process itself, and the various strategies and therapies currently offered. Calorie restriction, for example, reduces the risk of suffering from various age-related diseases. An anti-aging cream is primarily a skin care cosmetic moisturizer with the promise of making the wearer look younger by reducing, masking or preventing signs of aging. These signs include laxity (sagging), rhytids (wrinkles) and mild aging, including erythema (redness), dispigmentation (brown discoloration), sun elasticity (yellowing), keratosis (abnormal growth) and poor texture. The study found that drug regimens appeared to change biological age as measured by changes in DNA that accumulate with age.
