The truth about topical retinoids The money word in anti-aging skin care these days is retinoid -- so what is it exactly? Retinoids are basically derivatives of vitamin A, which you now know plays an integral part in your skin's health. "So by giving the body adequate retinoid, you can essentially make new skin tissue," says Canfield.

Retinol is the most common over-the-counter topical form of the vitamin, but unless you use a high concentration of it, you won't see significant improvement in fine lines and wrinkles. However, if you use too much retinoid, it can cause "toxicity to the skin and dying off of the skin cells," doing exactly the opposite of what it's intended to do.

That's why you may want to avoid it altogether and opt instead for topical tretinoin (find this in prescription creams like Retin-A or Retin-A Micro). Unlike retinol, which takes time to convert, tretinoin (another retinoid) provides more immediate results and "can be very effective in diminishing the appearance of fine lines and wrinkles," says Simpson. Start off slow with this ingredient though as too much of it too soon can irritate skin causing it to get red and peel.

Where it's found: If you've never used a retinoid, try an over-the-counter product that contains retinol or retinyl palmitate first (try SkinCeuticals Retinol 1.0, $59), then if you haven't seen the results you're after, talk to your doctor about trying a prescription for a tretinoin cream.

Applause, applause! We truly are what we eat, and our diets do show on our complexions. I disagree that a supplement isn't needed--our soil is depleted of all of the vitamins and minerals we need. And drinking lots of water is extremely important!
