Vitamin A Benefits: Collagen Regeneration and Pore Size

Posted Sep 14 2008 3:08pm

For this blog entry, we welcome a submission from Dr. Lisa Kellett, a Toronto, Canada dermatologist. Be sure to check out her veryinformative siteon treating many kinds of skin concerns.

Vitamin A products offer many benefits for maintaining the skin’s well-being. Vitamin A helps to even skin tone, reduce fine lines and normalize cell turnover. At prescription strength, they can also stimulate collagen renewal. Retinol (Vitamin A) concentrations range from 0.15 % to a super potent one 1% but just keep in mind that over-the-counter creams are not as effective as those available from a pharmacist.


The only thing that has been conclusively proven over long-term studies is that Vitamin A changes the structure of collagen. Vitamin A regenerates collagen, which plumps the skin and makes pores less visible. Pores (also known as pilosebaceous unit) become dilated because of excess oil and lack of collagen surrounding the pore. Using products with vitamin A helps support the pore walls, keeping them tight and small.


Retinol-based cosmetics are a great starting point, as they can brighten skin and improve its texture. Be aware that the aggressive nature of retinoids can cause irritation. It is important to wear sunscreen, as Vitamin A makes skin more photosensitive. Products with retinol or Vitamin A work as an anti-aging ingredient to treat scars, regenerate collagen and help prevent blackheads. Try adding pure Vitamin A drops (preferably as a 1% retinol concentration) to your oil-free moisturizer at night for optimal results.
