The Science of Anti-Pigmentation
RAYANS LEVISH BODY LOTION 300ML (100ML)
Drug Facts
Active Ingredients
INGREDIENT · DEPIGMENTING AGENT / TYROSINASE INHIBITOR
Alpha-Arbutin
also known as Alpha-Arbutin, α-Arbutin
Evidence
Function
May help support skin brightening and even tone through tyrosinase inhibition and melanin synthesis modulation
How it works
Alpha-arbutin undergoes hydrolysis to release hydroquinone, which research indicates may inhibit tyrosinase enzyme activity and potentially reduce melanin production in melanocytes. Studies suggest the ingredient works through competitive inhibition of tyrosinase, the key enzyme responsible for melanin synthesis. The mechanism may involve downregulation of melanin-synthesis-related genes, supporting its use in addressing hyperpigmentation concerns.
⚑ For Indian skin (Fitzpatrick IV–VI)
Alpha-arbutin has been shown in research to support melanin reduction across diverse skin types and may be particularly relevant for Fitzpatrick IV-VI individuals in Kerala where high UV exposure and genetic predisposition contribute to melasma and PIH. Studies indicate the ingredient's efficacy is not compromised in darker skin phenotypes; however, practitioners should monitor for delayed or uneven depigmentation patterns common in Indian skin, as PIH risk remains significant during treatment. The tropical Kerala climate with intense UVB exposure necessitates concurrent daily broadspectrum sunscreen use (SPF 50+) and consideration of sequential therapy; alpha-arbutin alone may be insufficient for moderate-to-severe melasma in this population. Combining with other tyrosinase inhibitors or tranexamic acid may enhance efficacy, though patch testing is advisable given variable skin sensitivity in pigmented populations.

Evidence
Function
Barrier support, melanin transfer inhibition, anti-inflammatory, skin tone regulation
How it works
Niacinamide functions through multiple pathways including inhibition of melanosome transfer from melanocytes to keratinocytes, thereby potentially reducing hyperpigmentation. Research indicates it modulates skin barrier function by supporting ceramide and lipid synthesis, while simultaneously exerting anti-inflammatory effects through NAD+ pathway involvement. Studies suggest niacinamide's transdermal delivery is pH-dependent, with neutral formulation pH (7.4) facilitating approximately twofold greater skin permeation compared to acidic pH, which may enhance its biological activity.
⚑ For Indian skin (Fitzpatrick IV–VI)
Niacinamide demonstrates particular relevance for Fitzpatrick IV-VI skin types, where post-inflammatory hyperpigmentation (PIH) and melasma represent significant clinical concerns, especially in Indian populations with genetic predisposition to melanin dysregulation. In Kerala's tropical climate with high UV exposure, niacinamide's dual mechanism—supporting barrier integrity against environmental stressors while inhibiting melanin transfer—offers protective benefits without photosensitization risk. Research indicates that niacinamide formulations optimized at neutral pH may enhance efficacy in darker skin phototypes where enhanced permeation facilitates superior melanin transfer inhibition, making it particularly suitable for Indian dermatological practice where melasma prevalence ranges from 8-40% in certain populations. Local humidity and heat may increase transepidermal water loss in tropical settings; niacinamide's barrier-strengthening properties may provide compensatory protection.

Ascorbic Acid
also known as Vitamin C
Evidence
Function
Antioxidant protection, collagen synthesis support, and melanin regulation
How it works
Ascorbic acid functions as a free radical scavenger, reducing oxidative stress that contributes to photoaging and hyperpigmentation. Research indicates it may support collagen cross-linking and stabilization through its role as a cofactor in hydroxylation reactions. Studies suggest ascorbic acid derivatives may suppress inflammatory cytokine pathways including interleukin-33, potentially benefiting barrier-compromised skin states. Evidence indicates it may modulate melanin synthesis pathways, though efficacy is dependent on formulation stability and skin penetration.
⚑ For Indian skin (Fitzpatrick IV–VI)
Ascorbic acid has been shown to support barrier function and may help address post-inflammatory hyperpigmentation (PIH), a significant concern in Fitzpatrick IV-VI skin types prevalent in Kerala. Studies on ascorbic acid derivatives suggest they may suppress inflammatory mediators that exacerbate PIH development in darker skin tones. In Kerala's humid tropical climate, the high instability of pure ascorbic acid necessitates stabilized derivatives such as tetrahexyldecyl ascorbate for effective formulation and penetration. Patients with Fitzpatrick IV-VI skin should be monitored for potential irritation during initial use, particularly in combination with other actives, and formulations should be pH-controlled (pH 3.5 or lower for efficacy without excessive irritation). Evidence suggests that well-formulated ascorbic acid preparations may support epidermal turnover and dermal matrix organization, which may help improve barrier resilience in darker skin types prone to reactive conditions.
Effective concentration
10–20 % (for pure ascorbic acid; derivatives may be effective at lower concentrations) (optimal ~15% (for pure ascorbic acid; derivatives may be effective at lower concentrations))
Clinical evidence
Tetrahexyldecyl ascorbate, a lipid-soluble derivative of ascorbic acid, has been shown to have superior stability and skin-mimicking properties compared to native ascorbic acid. Studies suggest this derivative may address both extrinsic photoaging and intrinsic hyperpigmentation without the formulation challenges of parent compound ascorbic acid.
