Specification

Description:TECHNICAL FIELD
The present disclosure relates to lightening hyperpigmented skin. More particularly, the present disclosure relates to a method of preparing a formulation and a kit for lightening hyperpigmented skin. More particularly, the present disclosure relates to a method of preparing a formulation and a kit for Melasma.
BACKGROUND
Melasma is a common acquired skin disorder characterized by symmetrical hyperpigmented patches, primarily affecting sun-exposed areas such as the cheeks, forehead, upper lip, nose, and chin. It predominantly affects women, particularly those of Asian, Latin American, Middle Eastern, and African descent with Fitzpatrick skin types III to VI. Studies indicate that melasma affects up to 40% of Southeast Asian populations. While its exact cause remains unclear, genetic predisposition, chronic sun exposure, pregnancy, oral contraceptive use, and certain antiepileptic drugs are recognized as key contributing factors. Beyond its physical manifestations, melasma can significantly impact psychological well-being, leading to feelings of shame, low self-esteem, social withdrawal, and depression.
Presently available treatments, such as Kligman’s formula—a combination of hydroquinone, retinoids, and corticosteroids—remain widely used but have notable drawbacks. Despite their effectiveness, these treatments often lead to a rebound effect, where hyperpigmentation returns upon discontinuation. Various therapeutic agents, including both plant-derived and synthetic compounds, have been explored to target different stages of melanin production. These include tyrosinase inhibitors, which suppress melanin synthesis, agents that block melanosome transfer to keratinocytes, and compounds that accelerate skin cell turnover. However, present therapies primarily address melasma as a pigmentary disorder driven by overactive melanocytes, overlooking underlying factors such as photoaging. In addition to the rebound effect, conventional treatments for melasma often cause skin irritation, redness, and increased sensitivity, particularly with prolonged use of hydroquinone and retinoids. Corticosteroids, if overused, can lead to skin thinning, telangiectasia (visible blood vessels), and steroid-induced acne. Moreover, many treatments require long-term adherence, and their efficacy varies based on individual skin type, making consistent and predictable outcomes challenging.
Therefore, there is a need for a method of preparing formulation and a kit for lightening hyperpigmented skin to overcome aforementioned problems.

It is to be understood that this disclosure is not limited to methods, and experimental conditions described, as such methods and conditions may vary.
Example 1:
A 16-week, open-label, single-arm clinical study was conducted to evaluate the efficacy, safety, and tolerability of the formulation in individuals with an mMASI score of ≤10. The formulation consisted of three serums (serum 1-3) containing quercetin, 4-n-tertbutylresorcinol, niacinamide, glutathione, ascorbic acid, retinaldehyde, and tranexamic acid, targeting various promoters in the melanogenesis pathway. The individuals were assessed at baseline, week 4, week 8, and week 12 by dermatologists and through clinical photography. Adverse events were documented at each visit, and participants' perceived efficacy and satisfaction were recorded. Additionally, the Melasma Quality of Life Survey (MELASQOL) was completed at baseline and at the end of treatment (week 12). To assess rebound pigmentation, follow-up evaluations were conducted one-month post-treatment (week 16).
Observation: The individuals were assessed at baseline, week 4, week 8, and week 12 by dermatologists and through clinical photography. Adverse events were documented at each visit, and participants' perceived efficacy and satisfaction were recorded. Additionally, the Melasma Quality of Life Survey (MELASQOL) was completed at baseline and at the end of treatment (week 12). The observations of the treatment on the individuals can be referred by Fig 2.
To assess rebound pigmentation, follow-up evaluations were conducted one-month post-treatment (week 16).
• Dermatologist-Assessed Efficacy (mMASI Scoring): Dermatologists performed Modified Melasma Area & Severity Index (mMASI) scoring at each evaluation point along with clinical photography. A progressive reduction in mMASI scores was observed throughout the study period, with a 32% reduction at week 4, 47% at week 8, and approximately 60% at week 12 compared to baseline (as shown in FIG. 3A).
• Patient-Perceived Efficacy: Participants assessed the effectiveness of the test formulations using a 5-point scale, where -1 indicated worsening, 0 indicated no improvement, and higher scores reflected increasing levels of improvement. A greater percentage of participants reported ‘marked’ or ‘moderate’ improvement at week 12 compared to week 4, while those reporting ‘mild’ improvement declined steadily over the treatment period (as shown in FIG. 3B).
• Patient Satisfaction: Participants evaluated their satisfaction with the treatment at weeks 4, 8, and 12, with ratings classified as ‘excellent,’ ‘moderately satisfied,’ or ‘not satisfied.’ An equal proportion of participants expressed satisfaction as either ‘excellent’ or ‘moderately satisfied,’ and no participants reported being ‘not satisfied’ with the formulations (as shown in FIG. 3C).
• Melasma Quality of Life (MELASQOL) Survey: The MELASQOL survey, assessing quality of life on a scale from 1 to 7, was conducted at baseline and week 12. A significant improvement in MELASQOL scores was observed at the conclusion of the 12-week treatment period, indicating enhanced quality of life for study participants (as shown in FIG. 3D).
Result: The study demonstrated a significant reduction in mMASI scores over the treatment period. mMASI stands for Modified Melasma Area and Severity Index. It is a validated scoring system widely used by dermatologist to evaluate the severity of melasma. It takes into account the extent of melasma pigmentation (area) and intensity of the pigmented patches (darkness). A 32% reduction from baseline was observed at week 4, followed by a 47% reduction at week 8, and close to 60% reduction at week 12. No, adverse events were noted by the dermatologists in any of the individuals participating in the study.
Additionally, no resistance to the treatment was observed among the participants. Compared to other depigmenting cosmeceutical formulations, either as monotherapies or in combination with antioxidants and tranexamic acid, the formulation exhibited both faster and superior efficacy. The treatment approach leveraged the lowest effective concentration of melanogenesis inhibitors while incorporating quercetin’s ability to mitigate production of senescent associated secretory phenotype (SASP) proteins by senescent cells in the epidermis and dermis, overcoming resistance commonly associated with conventional treatments.
Following discontinuation of the formulation, clinical improvement in melasma remained evident at the one-month follow-up. Importantly, there was no observable rebound in pigmentation following the cessation of application of the serums. In contrast, conventional therapies have shown a significant decline in efficacy within one month, with complete relapse to baseline levels within six months post-treatment. Moreover, some patients undergoing traditional treatments have experienced pigmentation rebound surpassing their initial condition.
Further, the participants rated their perceived efficacy as 'marked improvement' or 'moderate improvement' at the end of the study (week 12) compared to the beginning of the study (week 4). Additionally, subject satisfaction with the serums remained consistent as an equal proportion reported their satisfaction as 'excellent' or 'moderate', while none reported 'no satisfaction'. Lastly, there was a significant improvement in Melasma Quality of Life (MELASQOL) Survey, which evaluates quality of life for patients with melasma, at the conclusion of the 12-week study period when compared to baseline measurements.
Example 2
A formulation for lightening hyperpigmented skin was prepared by combining 6% w/v non-GMO sunflower phosphatidylcholine H90, 1.5% w/v 4-n-tert-butylresorcinol, 0.6% w/v quercetin, 0.4% w/v ceramides, 0.5% w/v lavender essential oil, 0.05% w/v all-trans-retinal, 2% w/v ethanol, 3% w/v niacinamide, 4% w/v tranexamic acid, 3% w/v glutathione, 1.5% w/v ascorbic acid, 2% w/v sodium ascorbate, 0.2% w/v sodium metabisulphite, 2% w/v glycerol, 2% w/v propylene glycol, 0.8% w/v xanthan gum, 0.5% w/v acacia, 0.3% w/v poloxamer 407, and 0.2% w/v potassium sorbate. The ingredients were dissolved in ethanol to obtain a mixture, which was then poured into a flask and heated at 50°C to evaporate residual ethanol, forming a thin lipid film. The lipid film was hydrated by adding an aqueous phase containing 3% w/v niacinamide, 3% w/v tranexamic acid, 2.5% w/v glutathione, 1.2% w/v ascorbic acid, 1.5% w/v sodium ascorbate, 0.1% w/v sodium metabisulphite, 1.5% w/v glycerol, 1.8% w/v propylene glycol, 0.6% w/v xanthan gum, 0.5% w/v acacia, 0.2% w/v poloxamer 407, and 0.2% w/v potassium sorbate, followed by heating at 40°C to convert the lipid film into a hydrated liposome suspension. The hydrated liposome suspension was sonicated at 15°C and homogenized at 12,000 rpm to reduce liposome size, and the pH was adjusted to 5.2 to obtain the final formulation. The final formulation included serum 1, serum 2, and serum 3.
Serum 1 was prepared by mixing 6% w/v non-GMO sunflower phosphatidylcholine H90, 2% w/v glycerol, 2% w/v ethanol, 2% w/v propylene glycol, 1% w/v 4-n-tert-butylresorcinol, 3% w/v niacinamide, 4% w/v tranexamic acid, 0.3% w/v acacia, 0.3% w/v xanthan gum, and 0.2% w/v potassium sorbate with ultra-pure water.
Serum 2 was prepared by mixing 6% w/v non-GMO sunflower phosphatidylcholine H90, 2% w/v glycerol, 2% w/v ethanol, 2% w/v propylene glycol, 0.5% w/v quercetin, 0.4% w/v ceramides, 3% w/v glutathione, 1.5% w/v ascorbic acid, 2% w/v sodium ascorbate, 0.2% w/v sodium metabisulphite, 0.2% w/v poloxamer 407, 1% w/v acacia, 0.8% w/v xanthan gum, 0.2% w/v potassium sorbate, and 0.5% w/v lavender essential oil with ultra-pure water.
Serum 3 was prepared by mixing 6% w/v non-GMO sunflower phosphatidylcholine H90, 2% w/v glycerol, 2% w/v ethanol, 2% w/v propylene glycol, 0.05% w/v all-trans-retinal, 0.5% w/v quercetin, 0.4% w/v ceramides, 0.2% w/v poloxamer 407, 1% w/v acacia, 0.8% w/v xanthan gum, and 0.2% w/v potassium sorbate with ultra-pure water.
Advantages of the present invention include:
• Rapid Onset and Enhanced Efficacy: The formulation demonstrates up to a 60% reduction in melasma within 12 weeks, exceeding the performance of conventional treatments such as topical 4% hydroquinone.
• Sustained Remission and Prevention of Rebound Pigmentation: Results are maintained post-discontinuation, with no observed rebound pigmentation following cessation of treatment.
• Targeting Cellular Senescence: The formulation addresses senescent fibroblasts, a key factor in relapse and rebound pigmentation associated with melasma treatment.
• Reduced Side Effects: Utilizing minimal effective concentrations of active agents results in improved tolerability and patient compliance.
• Multifaceted Mechanism of Action: The formulation combines depigmenting, antioxidant, anti-inflammatory, and anti-angiogenic effects.
• Liposomes with a particle size of 300 nm or below enables deeper penetration of active agents into the skin, enhancing delivery efficiency.
• A polydispersity index (PDI) of 0.3 or below ensures a homogeneous population of lipid vesicles, optimizing liposomal formulations for effective transdermal delivery.
