retinaldehüüd

Retinaldehyde, also known as retinal, is a form of vitamin A. It is an aldehyde derivative of retinol and plays a crucial role in vision. When light strikes the retina, retinaldehyde undergoes a chemical change, initiating a cascade of events that ultimately leads to the transmission of a visual signal to the brain. This process is essential for our ability to see.

Beyond its function in vision, retinaldehyde is also important for cell growth and differentiation. It influences the health and development of various tissues in the body. In the skin, it is recognized for its anti-aging properties. Topical application of retinaldehyde can help to reduce the appearance of fine lines and wrinkles, improve skin texture, and promote a more even skin tone. It works by increasing cell turnover and stimulating collagen production.

Retinaldehyde is often found in skincare products and is considered a gentler alternative to other retinoids, such as retinol, as it requires fewer conversion steps within the skin to become active. It is a key intermediate in the visual cycle and is involved in the synthesis of rhodopsin, the light-sensitive pigment in the rod cells of the retina. Its biological significance extends to maintaining epithelial tissue integrity and immune function.
