What are Retinoids?
Retinoids are a group of chemical substances that are either vitamers or chemically linked to vitamin A. Retinoids are used in medicine to control the proliferation of epithelial cells. Several transcription factors, including RAR and RXR, are found in the nucleus of diverse cells and are regulated by them. Retinoids also play an important role in intercellular communication, allowing signaling to adjacent cells via nuclear receptor binding and thereby controlling epithelial cell development and reproduction.
Benefits of Retinoids:
- Reduces fine lines
- Reduces wrinkles
- Stimulate production of new blood vessels in skin
- Improves skin colour
- Fading age spots
- Softening rough patches of skin
- Retinoids for warts
- Essential for vision
Sources of Retinoids:
- Fortified milk
- Swiss cheese
So, should you start using retinoids?
If you want to cure or prevent wrinkles, fine lines, pigmentation, scarring, and other skin issues, starting with over-the-counter retinol or even prescription-strength tretinoin in your late 20s or early 30s is a fantastic place to start. Around this period, the body begins to produce less collagen, at a slower rate than in previous years. Of course, your lifestyle and the amount of sun damage you’ve collected over those years have a role!
