Background: Patients with acne scarring often have several types of acne scars, and combination therapies have demonstrated superior success to single treatment modalities. Chemical reconstruction of skin scars (CROSS) has gained popularity as the treatment for ice-pick scars and fractionated laser therapy for rolling and boxcar scars. However, no study has looked at combination therapy with CROSS and fractionated non-ablative laser for the treatment of atrophic acne scars. Read More

Currently, consumers' demand for sunscreens derived from natural sources that provide photoprotection from ultraviolet (UV) radiation is pushing the cosmetic industry to develop breakthrough formulations of sun protection products by incorporating plant antioxidants as their active ingredients. In this context, the present study was initiated to evaluate the antioxidant and photoprotective properties of the underutilized peel extract (HPPE) using spectrophotometric techniques. The phytochemical screenings of HPPE conducted via high-performance liquid chromatography (HPLC) and ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS) revealed the presence of phenolic acids and flavonoids as the major secondary metabolites in HPPE.

Turning to peeling in a dermatological sphere is extensively common and has been used for a long time. From the use of single acids moving on to the so-called compound peelings (associations of more than one substance in the same product) and the combined peelings which take advantage of the action of different substances in a synergistic manner (different products are applied sequentially) in order to best guarantee a greater effectiveness of the treatment for the recommended target. Superficial peelings, combined and not, have led to a drastic reduction in the percentage of incidence of adverse events typical of medium and deep peels. Read More

Mounting evidence from clinical and epidemiological studies suggests that lycopene, the most abundant carotenoid in tomatoes, may be beneficial in the prevention or treatment of some important diseases. Ripe tomato peels are the richest source of lycopene, but the use of conventional solvent extraction methods without pretreatment of the plant material results in very poor recovery. The reason lies in the localization of lycopene in the plant tissue and the low permeability of the latter to solvent molecules. Read More
