3. Radiesse
A long-lasting filler made up of calcium hydroxylapatite crystals, a compound found in bones and tooth enamel.
Best for: Sculpting areas like the chin and pumping up hollow cheeks and temples. (It’s not recommended for lips or the eye area.)
Cost: $500 to $1,000 per treatment (that's for one syringe; may need more, depending on the condition of the patient’s skin).
Full effect: Improvement is immediate but complete results occur within a week or so.
Results last: 1 to 2 years.

4. Sculptra
A thin, watery filler made up of poly-L-lactic acid, a substance used in implants and dissolvable sutures.
Best for: Creating overall smoothness and volume on faces that look gaunt or melted away. Wherever it’s deposited, Sculptra prompts the skin to make and repair collagen. The result: a gradual filling-out effect.
Cost: $600 to $1,200 for a one-vial treatment. Depending on your age, degree of hollowing and response to the product, you may need 2 or 3 treatments over 6 months (and in some cases, quite a few more).
Full effect: 6 months after the last treatment.
Results last: Up to two years.

5. Ulthera and Thermage

Ulthera (focused ultrasound) and Thermage (which uses radio-frequency energy) heat up tissue deep inside the skin to tone and tighten.
Best for: Firming skin on the face and neck, tightening mild jowling when you’re in your thirties or forties and creating a subtle, nonsurgical brow lift. Ulthera and Thermage go deep into skin tissue to stimulate it to produce collagen, so you get more lift and smoothness over time. Thermage can also be used to treat eyelids. Note: Results vary. Some patients see a lot of tightening; others, very little.
Cost: $1,500 to $3,000 per treatment area.
Full effect: In 2 to 3 months. Some patients see major results within 24 hours.
Results last: A year or more.

6. Fractional CO2 Lasers and other Resurfacing Lasers
Treatments (such as Fraxel) in which tiny beams of light are used to damage skin below the surface, thus triggering new cell growth. High-tech fractional lasers spread out the damage in microscopic treatment zones, for deeper penetration and faster healing.
Best for: Resurfacing sun-damaged skin—smoothing out fine lines and crosshatches, erasing brown spots and some redness, refining pores, evening out tone and stimulating collagen for a firmer, more radiant effect. Fractional lasers can also reduce deep acne and chicken pox scars, which until now had been hard to treat.
Cost: About $1,500 each session for a gentler treatment (a series of 3 to 5 is recommended) or $4,000 to $5,000 for a more intense, ablative procedure. (Ablative lasers vaporize the top layers of the skin. Translation: 1 to 2 weeks for healing, a full month out of the sun and more dramatic results.)
Full effect: 6 months after the last treatment.
Results last: Several years.

7. Vascular lasers
Pulsed-dye lasers that target redness in the skin, vaporizing red pigmentation or tiny broken blood vessels.
Best for: Obliterating brokencapillaries, red spots and port-wine stains.
Cost: It varies. It might cost $150 to zap one red spot, $200 to $300 to treat the area around the nostrils and about $600 to address diffuse redness all over the face. Depending on your age and degree of redness, you may need 3 sessions, spaced 4 to 6 weeks apart.
Full effect: 2 to 3 weeks after your last treatment.
Results last: At least a year (broken capillaries around the nose tend to return, as does high color in the cheeks if you have rosacea or go back in the sun)—but possibly forever: Spider veins around a scar are usually gone for good.
