Key messages

  • Il presente studio ha valutato l’efficacia e la tollerabilità di un gel, applicato 1 volta die, contenente ac. salicilico al 3% + curcuma e un idratante esfoliante contente ac. salicilico a bassa concentrazione + burro di karité, in monoterapia o in associazione ad altri trattamenti per la psoriasi.
  • L’applicazione 1 volta die del prodotto da banco ha dimostrato tollerabilità ed efficacia eccellenti nella psoriasi in placche dopo 12 settimane di trattamento.


This study examined the efficacy and tolerability of a once-daily regimen of a 3% salicylic acid treatment gel containing turmeric and a low concentration of salicylic acid plus shea butter exfoliating moisturizer when used as monotherapy or in as an adjunct to other Rx psoriasis medications.

Patients and methods
This single-site 12-week study enrolled 20 subjects >18 years of age with mild-to-moderate psoriasis involving <10% body surface area. Assessments were performed at baseline and Weeks 4, 8, and 12 using a 5-point scale (0 = none to 4 = severe). The investigator-assessed efficacy (changes from baseline for erythema, desquamation, induration, and overall global assessment [IGA]) and tolerability (irritation and edema). Study subjects assessed efficacy parameters of redness, scaling, and overall skin problems along with tolerability parameters of stinging, burning, itching, and irritation. Subjects applied the turmeric and salicylic acid treatment gel along with a moisturizer once daily to all affected areas.

Half (50%) of the subjects were using concomitant Rx psoriasis treatments, while the other 50% received the study psoriasis treatment regimen as monotherapy. Investigator assessments of erythema, desquamation, induration, and IGA scores showed significant reductions from baseline (p ≤ 0.021) at Weeks 4, 8, and 12. At Week 12, these reductions reached 48%, 46%, 51%, and 48%, for these parameters, respectively. The investigator observed no irritation or edema at any time point. Subject assessments of redness, scaling, and overall improvement demonstrated significant reductions in 8 of 9 assessments (p ≤ 0.037). The subjects reported mild irritation at Weeks 4, 8, and 12. No treatment compliance issues or adverse events related to study product occurred during the study.

A once-daily over-the-counter (OTC) turmeric/salicylic acid gel followed by a shea butter/salicylic acid exfoliating moisturizer demonstrated excellent tolerability and efficacy in plaque-type psoriasis after 12 weeks of once-daily use.
