- Brief Summary
This research is a clinical study with a single-blind randomized clinical trial design (randomized controlled trial) in multicenters at two Dermatology and Venereology Education centers in Indonesia.
This study aims to determine the effectiveness and safety of PSP as adjuvant therapy for melasma.
This research will be attended by 33 research subjects
- Detailed Description
Melasma is one of the most common hyperpigmentary dermatoses, found mostly in Asian or Hispanic people living in tropical areas.
The goal of melasma treatment is to remove existing pigmentation and to inhibit pigmentation. Until now, hydroquinone (HQ) is still used as the Gold Standard for melasma therapy.
Various epidemiological studies calculate the prevalence of melasma, it is estimated that the prevalence of melasma is 1% in the general population and in high risk populations it is 9 - 50%. This large variation is due to differences in skin type, ethnicity, and level of UV exposure
The diagnosis of melasma is based on the clinical picture, namely light to dark brown macules with irregular edges and a distribution that tends to be symmetrical, especially on the face. Supporting examinations can be carried out to determine the degree of melasma and monitor the therapy given.
This research is a clinical study with a single-blind randomized clinical trial design (randomized controlled trial) in multicenters at two Dermatology and Venereology Education centers in Indonesia. The number of samples was 33 divided into 2 groups based on consecutive sampling to obtain subjects who met the eligibility criteria. Then subjects will be allocated into two groups using block randomization.
What is meant by group 1 is control, getting SPF 30 sunscreen cream in the morning and only 2% Hydroquinone cream at night without a combination cream and facial soap that can be used in the morning and evening. Meanwhile, group 2, the treatment group, used PSP cleanser, PSP Day Cream and SPF 30 sunscreen in the morning and used Hydroquinone 2% and PSP Night Cream at night and PSP cleanser which was used in the morning and evening before using the cream.
Data collection and research will be carried out for 3 months and data management and analysis will be carried out for the following 1 month. Follow up will be carried out at Week 4, Week 8 and Week 12. Each follow up will be analyzed as follows:
* Physical examination
* 5 position face photos
* Mexameter examination
* Dermoscopic examination
* Check wood lamp
* MelasQoL check
* Calculation of mMASI Score
* Completing the Investigator's Global Assessment questionnaire
* Completing the Patient's Global Assessment Questionnaire
* Completing the Investigator's Tolerability Assessment questionnaire
Data is recorded in research status which is then compiled into a master table. After recording the research results is complete, the masking code is opened for statistical analysis. Data analysis used statistical tests in accordance with the intention to treat approach with research subject analysis methods based on intervention groups. The research results are attached in the form of narratives, frequency tables and graphs. The data will be processed statistically by a statistical consultant. Thus, data from SPs who dropped out will be included in the data analysis. The hypothesis test to assess changes in the primary end point (degree of melasma) during the study measurement series (baseline, M4, M8, M12) will be assessed using the Independent Sample T-test. Normality was tested using the Kolmogorov Smirnov normality test which was confirmed with the Coefficient of Variation. The data was processed statistically by a statistical consultant using SPSS® version 21.

Group Intervention Description Group 2 (PSP Group) Pigment Solution Program Group 2, the treatment group, used PSP cleanser, PSP Day Cream and SPF 30 sunscreen in the morning and used Hydroquinone 2% and PSP Night Cream at night and PSP cleanser which was used in the morning and evening before using the cream.
- Primary Outcome Measures
Name Time Method Change of Melasma Severity based on Wood's Lamp re-evaluation on day 84 of therapy Epidermal Type/ Dermal Typed/ Mixed Typed
Compare Quality Of Life based on MelasQoL Score re-evaluation on day 84 of therapy based on MelasQoL Score minimum score: 7 maximum score : 70
Change of Melasma Severity based on modified Melasma Severity Index (mMASI) score. re-evaluation on day 28, day 56 and day 84 of therapy The range of values for mMASI is between 0 and 24 which can then be divided into mild melasma (0-8), moderate (8-16), and severe (16-24).
The range of values for mMASI is between 0 and 24 which can then be divided into mild melasma (0-8), moderate (8-16), and severe (16-24).
improvement occurs if the mMASI score decreases by \<50% from the previous visit worsening if score persists or mMASI Score Increase \>50%Change of Melasma Severity based on Investigator Global Assesment (IGA). re-evaluation on day 28, day 56 and day 84 of therapy Assessment of response to therapy as follows:
* No effect: 0 (no visible change in Pigmentation)
* Mild: 1 (decreased visible pigmentation, but still visible boundaries)
* Moderate: 2 (obvious decrease in Pigmentation, but still limited visible)
* Very good: 3 (disappearance of all visible abnormalities Pigmentation)
improvement if there is \>50% improvement from the previous visit worsening if score persists or improvement \<50%Change of Melanin and Erythema Index Based on Mexameter re-evaluation on day 28, day 56 and day 84 of therapy improves if there is a decrease in melanin levels \> 50% from the initial visit It is said to be bad or persistent if there is no decrease in melanin levels or there is a decrease of \<50%
Change of Melasma Severity based on Dermoscopy re-evaluation on day 84 of therapy based on Dermoscopy
Telangiectasis score assessment using a 5-point dermoscopy-scale:
0 = No visible capillaries.
1 = Elongated capillaries accompanied by dilation, not visible to the naked eye. 2 = Moderate telangiectasis that is beginning to be visible to the naked eye.
3 = Severe telangiectasis characterized by reduced capillary loops. 4 = Very severe telangiectasis characterized by dilatation and loss of capillary loops.Change of Melasma Severity based on Investigator Tolerability Assesment (ITA). re-evaluation on day 84 of therapy is one method of evaluating patient tolerability of products which is assessed subjectively by investigators.
Assessment of patient tolerability as follows:
* 0 = no tolerability,
* 1 = moderate tolerability,
* 2 = good tolerability,
* 3 = very good tolerability.
tolerability was good if the score improved \>50% from the previous visit worsening if score persists or improvement \<50%Change of Melasma Severity based on Patient's Tolerability Assesment (PtGA). re-evaluation on day 28, day 56 and day 84 of therapy one method of evaluating the response to therapy in melasma which is assessed subjectively by the patient. The response to therapy can be assessed as follows
* No or slight response: \< 25% improvement
* Moderate response: 25% - 50% improvement
* Good response: 50% improvement - \< 75%
* Excellent response: improvement \> 75%
The response is said to be good if the score is above 50% since the previous visit
