While we can't say for sure whether collagen supplements will give your skin a youthful boost, our experts do have a few tried-and-true tips. As far as topical solutions go, Jegasothy says that retinoids help stimulate collagen production. Though, keep in mind that most of the research has been done on prescription Retin-A, says Jegasothy. Avene RetrinAL 0.1 Intensive Cream, $70, is formulated with vitamin E (an antioxidant) for free radical protection, as well as Avene's calming thermal spring water.

In addition to getting it through your diet, applying vitamin C topically can also help stimulate collagen production. Among sin-care junkies SkinCeuticals C E Ferulic, $165, tends to be the holy grail of serums, but we like these vitamin C serums too.

Finally, some lasers can also help stimulate collagen production. "Lasers used to tighten skin -- like Ultherapy -- create a mild thermal injury in the dermis that wakes up the skin into creating more collagen," says Jegasothy.
