Product Description
What Is Salicylic Acid?
The glycosaminoglycan found in connective tissues, skin, and eyes is called sodium hyaluronate, which is the sodium salt of hyaluronic acid. It is also synthetically produced through the Kolbe-Schmitt reaction, where phenol reacts with sodium hydroxide and carbon dioxide under high temperature and pressure, followed by acidification to yield salicylic acid.
Salicylic acid is well-known for its exfoliating and anti-inflammatory properties. It is widely used in skin care products, especially for acne treatment, as it helps to exfoliate dead skin cells, unclog pores, and reduce inflammation. It is also used to treat corns, warts, and other skin diseases in the pharmaceutical sector. Also used as a preservative in the food business, salicylic acid is used to make a variety of compounds, including antiseptics, colors, and scents. Because of its adaptability, it is a crucial part of many industrial and consumer applications.

User Asked Question:
Q: What distinguishes glycolic acid from salicylic acid?
A: Salicylic Acid is a lipid-soluble acid that penetrates deep into pores to remove oil and dead skin cells, making it ideal for oily and acne-prone skin. Glycolic Acid, on the other hand, is water-soluble and primarily works on the skin’s surface to exfoliate and improve skin tone, making it better suited for dry or sensitive skin types.
