Target and La Roche-Posay Singapore pages verify formula context including niacinamide, glycerin, dimethicone, propylene glycol, 2-mercaptonicotinoyl glycine, sodium hyaluronate, capryloyl salicylic acid, retinyl palmitate, tocopherol, fragrance, and CI 17200 / Red 33. In cosmetic terms, it fits a routine for facial hyperpigmentation appearance, dark-spot appearance, post-blemish marks, uneven-looking tone, radiance, and hydration or skin-feel support. Pair daytime use with sunscreen, and introduce gradually if fragrance, exfoliating-adjacent ingredients, or retinoid-adjacent ingredients are concerns. ## What is in the formula The Target and La Roche-Posay Singapore pages cross-check the main formula story: water, dimethicone, niacinamide, glycerin, propylene glycol, polysilicone-11, silica, silicone emulsifiers, Cystoseira tamariscifolia extract, 2-mercaptonicotinoyl glycine, sodium hyaluronate, carnosine, dipotassium glycyrrhizate, caprylic/capric triglyceride, capryloyl salicylic acid, caprylyl glycol, retinyl palmitate, tocopherol, phenoxyethanol, CI 17200 / Red 33, and fragrance. Melasyl is the brand’s name for the 2-mercaptonicotinoyl glycine ingredient story, while niacinamide is the familiar tone and barrier-feel ingredient. ## What the brand and retailer say it does Target identifies the product as Mela B3 Dark Spot Serum with Melasyl and 10% Niacinamide. The La Roche-Posay Singapore page lists Melasyl and niacinamide as key ingredient modules and provides the full INCI. Those phrases are product-positioning facts, not independent outcome promises. The useful reader-facing facts are the product type, 1 fl oz size, Melasyl and 10% niacinamide cues, silicone-rich serum base, sodium hyaluronate hydration context, fragrance and colorant disclosures, and tolerance-relevant later-list ingredients such as capryloyl salicylic acid and retinyl palmitate. ## How the ingredients function in cosmetic skincare Melasyl, listed as 2-mercaptonicotinoyl glycine, is the proprietary dark-spot-positioned ingredient in this serum. Niacinamide supports tone appearance, radiance, and barrier-feel language. Glycerin, propylene glycol, and sodium hyaluronate support hydration and formula slip, while dimethicone, polysilicone-11, and related silicones support smooth skin feel. Capryloyl salicylic acid and retinyl palmitate appear later in the INCI, so this page treats them as formula-context ingredients rather than making a strong exfoliation or retinoid claim. Fragrance and Red 33 are useful disclosures for reactive skin. ## Who the formula is positioned for The serum is positioned for people researching facial hyperpigmentation appearance, dark spots, post-blemish marks, uneven-looking tone, and dermocosmetic brightening-serum routines. It may appeal to shoppers curious about La Roche-Posay’s Melasyl ingredient story and a 10% niacinamide formula. Sensitive or reactive skin should introduce it gradually because fragrance, colorant, capryloyl salicylic acid, and retinyl palmitate can matter in a leave-on routine. If pigment changes are new, irregular, one-sided, quickly changing, or possibly melasma-related, personalized clinician guidance is more appropriate than product research alone. ## How it fits in a routine Use it as a serum step before moisturizer, following the product label and tolerance. In any hyperpigmentation-appearance routine, daytime sunscreen is central because UV exposure can keep dark spots looking more visible. If the routine already includes retinoids, exfoliating acids, benzoyl peroxide, strong vitamin C, or other brightening products, introduce this serum gradually so tolerance is easier to read. If irritation, burning, peeling, or rash appears, pause and simplify before adding more active products. ## When a dermatologist conversation makes sense A dermatologist conversation makes sense for new or rapidly changing pigment, irregular borders, one-sided pigment changes, suspected melasma, pigment near eyes or mucosal areas, or marks that follow significant acne or irritation. It also makes sense if cosmetic routines trigger burning, rash, persistent peeling, or worsening sensitivity. Prescription options, hydroquinone questions, chemical peels, laser, and other procedures are outside a general product-facts answer and should be handled with personalized guidance. ## Ranked Products La Roche-Posay Mela B3 Dark Spot Serum is included because this Question is about that exact product. Target and La Roche-Posay Singapore identify a serum positioned around Melasyl and 10% niacinamide, with glycerin, sodium hyaluronate, dimethicone, propylene glycol, fragrance, colorant, capryloyl salicylic acid, and retinyl palmitate context. TRUE Serums EGF Serum is included as the facial-hyperpigmentation-aligned secondary entry; its product page connects the formula to dark spots, sun-damage appearance, dullness, EGF, Collaxyl, green tea, and olive leaf extract. The two entries are listed in parallel without a product-to-product verdict. ## Related Entities - [AAD — How to fade dark spots in darker skin tones](https://skinknowledgebase.com/sources/aad-fade-dark-spots-darker-skin-tones) - [Postinflammatory hyperpigmentation](https://skinknowledgebase.com/sources/dermnet-postinflammatory-hyperpigmentation) - [Target Product Page — La Roche-Posay Mela B3 Dark Spot Serum](https://skinknowledgebase.com/sources/target-product-page-la-roche-posay-mela-b3-dark-spot-serum) - [La Roche-Posay Singapore Product Page — Mela B3 Serum](https://skinknowledgebase.com/sources/la-roche-posay-singapore-product-page-mela-b3-serum) - [Official product page — TRUE Serums EGF Serum](https://skinknowledgebase.com/sources/official-product-page-true-serums-egf-serum) - [Melasyl](https://skinknowledgebase.com/ingredients/melasyl) - [Niacinamide](https://skinknowledgebase.com/ingredients/niacinamide) - [Hyaluronic Acid](https://skinknowledgebase.com/ingredients/hyaluronic-acid) - [Facial Hyperpigmentation](https://skinknowledgebase.com/concerns/facial-hyperpigmentation) - [La Roche-Posay Mela B3 Dark Spot Serum](https://skinknowledgebase.com/products/la-roche-posay-mela-b3-dark-spot-serum) - [TRUE Serums EGF Serum](https://skinknowledgebase.com/products/true-serums-egf-serum) - [Dark Spots From Acne](https://skinknowledgebase.com/concerns/dark-spots-from-acne) - [Dullness](https://skinknowledgebase.com/concerns/dullness)
