Problem: Undereye Circles and Bags
Solution: Juvederm. A doctor can inject this filler into the tear-trough area to eliminate those shadowy hollows. Because the procedure targets such a small area, you'll be in and out the door very quickly.
Time: Up to 15 minutes
Cost: $500 to $750 (per syringe)
Pain Factor: x x x x x
"Since you're numbed with a topical cream, you should barely feel any discomfort," says Nashville-based dermatologist Michael Gold.
Maintenance Product: Lab Series Skincare for Men MAX LS Instant Eye Lift. This gel brightens dark circles instantly and tightens skin over time. $42;

Problem: Sun Spots
Solution: Photorejuvenation. This treatment blasts targeted bursts of high-intensity light at dark pigmentation. Skin tone will even out after a single session, but New York City dermatologist Fredric Brandt suggests three to five follow-ups for optimal results.
Time: 15 to 45 minutes
Cost: Starts at $1,200
Pain Factor: x x x x x
Very minor temporary irritation or redness.

Problem: Thinning Hair
Solution: IllumiWave180. This low-level-energy laser stimulates circulation and follicle growth. It's a treatment, not a cure; you'll need several sessions a week for six months (depending on the extent of your thinning), then one weekly for maintenance.
Time: 20 minutes
Cost: $50
Pain Factor: x x x x x
Because it's a noninvasive laser, "there really is no pain," says New York City dermatologist Doris Day.

Time: 15 minutes
Cost: Starts at $350
Pain Factor: x x x x x

Cost: $500 to $1,000 (for full-face treatment)
Pain Factor: x x x x x
A minor sting during treatment.
