Randomized clinical trial to assess the effectiveness and tolerability of Mela B3 serum in combination with 35% glycolic acid peel vs. 35% glycolic acid peel for the treatment of various hyperpigmentation conditions (melasma, post-inflammatory hyperpigmentation and solar lentigo) and signs of aging in a population of participants from the Autonomous City of Buenos Aires, Argentina.

Interventional, monocentric, randomized, parallel-group, full-face clinical trial to analyze the effect of MB3 serum in combination with GAP 35 vs. GAP 35 alone.

• Group A: GAP 35 on Day0 + post-peel
• Group B: MB3 serum from Day-15 to Day84 + GAP 35 on D0 + post-peel Duration: 99 days Visits: Day-15, Day0, Day28, Day56, Day84 (5 visits)

Evaluations:

• To evaluate the occurrence and severity of post-procedure pigmentation changes, including the development or worsening of PIHP, melasma and solar lentigo, following treatment with MB3 serum and GAP35 determined by change in mMASI, PAHPI socre and SL score.

• To demonstrate the effectiveness of MB3 serum in combination (pre- and post-treatment) with GAP 35 in the treatment of the signs of skin aging:

  • Fine lines and wrinkles
  • Pores
  • Skin smoothness
  • Skin tone, evenness and luminosity
  • Skin firmness and elasticity
  • Skin flaccidity

• To assess the tolerability of MB3 serum in combination with GAP 35

• To evaluate the quality of life of subjects using QOL (quality of Life) questionnaires

• To evaluate the satisfaction of the participants with MB3 serum and cosmeticity using patient satisfaction questionnaire and cosmeticity questionnaire.

• To evaluate the changes in skin pigmentation using colorimeter measurements in areas affected by melasma, PIH and SL before and after treatment with MB3 serum and GAP35.

• To illustrate the efficacy of the treatment determined by using VISIA imaging.

Inclusion Criteria:

1. Women and men

7. Willingness to avoid contraindicated products (irritants, other depigmenting agents)

8. Signing of written informed consent

Exclusion Criteria:

1. Pregnant, breastfeeding or with pregnancy plans.

6. Participant using irritating products (require a washout period of at least 2 weeks).
7. Use of medications that may induce melasma, such as antiepileptics (requires a washout period of 1 month).
8. Use of other products with depigmenting activity (requires a washout period of 1 month).
9. Other facial dermatoses or known photosensitivity, or a pre-existing or latent dermatologic health condition and/or disease on the face (e.g., psoriasis, rosacea, acne, eczema, seborrheic dermatitis, severe excoriations) that, in the judgment of the investigator, are considered inappropriate for participation or may interfere with study results.
10. Topical treatments applied to the face (requires a 2-week washout period).

15. Facial treatment with microdermabrasion within 6 weeks prior to study entry.
16. Persons with visible tanning, scars, moles, excessive hair or other dermal conditions on the face that, in the judgment of the investigator, may influence the results of the study.
17. History of skin cancer, immunosuppression or immunodeficiency disorders (including HIV infection or AIDS), or current use of immunosuppressive drugs.
18. Uncontrolled disease such as asthma, diabetes, hypertension, hyperthyroidism or hypothyroidism. Persons with multiple health conditions may be excluded, even if controlled by diet or medication.
19. Participation in another clinical trial within one week prior to entering this study.
