Vitamin A acid is a skincare ingredient that is often misspelled as "retin-A". However, the proper spelling should be "tretinoin", pronounced /trɛtɪnɔɪn/. The "v" in "vitamin" is pronounced as /v/ while the "a" is pronounced as /eɪ/. The word "acid" is pronounced as /æsɪd/. Proper spelling and pronunciation are crucial when using skincare products as it ensures that the correct and safe ingredient is being used for the benefit of the skin.
Vitamin A acid, also known as tretinoin or all-trans retinoic acid, is a synthetic derivative of vitamin A that is widely used in dermatology for various skin conditions. It falls under the category of retinoids, which are chemical compounds related to vitamin A.
Vitamin A acid is primarily used topically to treat acne, fine wrinkles, and skin discoloration. It works by regulating the growth of skin cells, reducing inflammation, and enhancing collagen production. As a result, it promotes the turnover of skin cells, unclogs pores, and improves the overall appearance and texture of the skin.
In addition to its applications in dermatology, vitamin A acid can also be used orally in the treatment of acute promyelocytic leukemia (APL), a type of cancer of the blood and bone marrow. It is known to induce differentiation of leukemic cells, impeding their growth and proliferation.
It is important to note that vitamin A acid may cause skin irritation, redness, and increased sensitivity to sunlight. Therefore, it is advisable to use it as prescribed by a healthcare professional and to follow appropriate sun protection measures when using this medication.
Overall, vitamin A acid is a potent and versatile compound used in both dermatology and oncology, offering therapeutic benefits for various skin conditions and specific cancers.
