Retinoid or retinol, commonly known as Vitamin A plays role in the skin antiaging process, the new study found.
Vitamin A is naturally found in:
- Leafy green vegetables (kale, spinach, broccoli), orange and yellow vegetables (carrots, sweet potatoes, pumpkin and other winter squash, summer squash)
- Red bell pepper.
- Cantaloupe, mango.
- Beef liver.
- Fish oils.
Around 3000 years ago, people in Ancient Egypt already knew about the benefits of Vitamin A. The people applied beef liver to the eyes to cure nighttime blindness.
Vitamin A deficiency is very rare nowadays. However, researchers around the world are trying to work out how to use Vitamin A to make the skin look younger. There are few studies that show that Vitamin A is, actually, making the skin look more youthful.
There are a few problems with what form of Vitamin A to apply to the skin and how. Some research showed that long-term application of some forms of Vitamin A was very effective over the 6-month long trial. However, some people were not patient enough to continue for that long and used other creams. Some people experienced irritation of the skin and aborted the trial.
At the moment, there is no firm information on what and how to use it in order to deliver Vitamin A to the skin cells. A general advice from some specialists in skin antiaging is to have a healthy diet, regular exercise, enough sleep and an application of Vitamin A (retinol) cream from some reputable manufacturer.
