The plasma fractional radiofrequency and transepidermal delivery of platelet-rich plasma using ultrasound is useful in the treatment of striae distensae.

IFUS can be used as a non-invasive, skin-tightening procedure for infraorbital laxity. No serious, permanent, or delayed side effects were noted up to 6 months post treatment. Thus, this procedure can be effective and safe in the treatment of decreased laxity of the lower eyelids.

The Thermage and pulsed dye laser appear to be an effective treatment for striae distansae.

Corticosteroids are widely used therapeutic agents that have as a major side-effect the impairment of wound healing. Two hypotheses were tested: 1) that antiinflammatory corticosteroids decrease the local insulin-like growth factor-I (IGF-I) response to injury; and 2) that locally administered IGF-I would overcome methylprednisolone-mediated suppression of healing. The IGF-I concentration was measured in fluid from wire mesh cylinder wounds in rats given saline or methylprednisolone im. Rats receiving 8 and 16 mg had decreased wound IGF-I levels of 32% and 56%, respectively, compared to the saline-injected controls. IGF-I was infused (15 micrograms/day) by osmotic minipumps into wire mesh cylinder wound chambers of methylprednisolone (8 mg)-treated rats for 7 and 14 days. Methylprednisolone decreased wound DNA to 21%, hydroxyproline to 30%, and total protein to 5% of the values found in saline-infused controls. A 14-day treatment with IGF-I completely reversed the effect of methylprednisolone and increased DNA, hydroxyproline, and total protein to 216%, 109%, and 96% of saline control values, respectively. In conclusion, corticosteroids depressed wound IGF-I concentrations in rats, and an infusion of IGF-I into wound chambers reversed the corticosteroid-induced impairment of wound healing, as determined by the DNA, hydroxyproline, and total protein contents in wound chambers.

Hyaluronic acid filler intradermal injection with special injector is a safe and effective method for correction of nasojugal groove.
