Yuderma Melarid-TRX Serum – Tranexamic Acid + Kojic Acid Melano Correction Serum

Yuderma Melarid-TRX Serum is a lightweight, fast-absorbing melano-correction serum designed to improve dull, uneven, and pigmented skin.
With a targeted blend of Tranexamic Acid, Kojic Acid, Alpha Arbutin, Niacinamide, and gentle Fruit AHAs, this serum works to brighten the skin, soften dark spots, refine texture, and improve overall clarity over time.

Suitable for all skin types — even sensitive — it provides daily pigmentation support while maintaining skin comfort, making it ideal for those dealing with melasma, sun spots, post-acne marks, or uneven tone.

FAQs

Q1. How do Tranexamic Acid and Kojic Acid in Melarid-TRX Serum target pigmentation through different pathways?
A1. These two actives interrupt melanogenesis at distinct stages. Tranexamic Acid inhibits the plasmin-mediated UV signalling cascade — specifically, it blocks the prostaglandin and arachidonic acid signals that UV triggers to stimulate melanocyte activity, reducing the upstream trigger for new melanin production. Kojic Acid directly chelates the copper at tyrosinase's active site, deactivating the enzyme responsible for converting tyrosine to melanin. The combination interrupts the pigmentation process at two separate points: before melanocyte stimulation (Tranexamic Acid) and at the enzyme level (Kojic Acid), producing more complete brightening than either molecule achieves alone.

Q2. What does Alpha Arbutin in Melarid-TRX Serum add to the formula?
A2. Alpha Arbutin is a glucoside derivative of Hydroquinone — it inhibits tyrosinase similarly to Kojic Acid but through a different binding mechanism, and hydrolyses slowly to release active Hydroquinone-equivalents in the epidermis without the skin sensitisation risk of free Hydroquinone. In Melarid-TRX, Alpha Arbutin adds a third tyrosinase-inhibiting mechanism alongside Kojic Acid, broadening the blockade against melanin synthesis. Niacinamide (Vitamin B3) in the formula adds a fourth pathway — blocking melanosome transfer from melanocytes to keratinocytes — so even melanin that is produced is prevented from being deposited visibly in the skin.

Q3. Is Melarid-TRX Serum safe and effective for PIH from acne on Indian skin?
A3. Yes — this formula is specifically well-suited for post-inflammatory hyperpigmentation on Fitzpatrick III–VI South Asian skin. Tranexamic Acid has an excellent safety profile on darker skin tones and effectively reduces the inflammation-driven melanocyte stimulation that causes PIH after acne. Alpha Arbutin and Niacinamide are both established as safe for long-term daily use on darker skin without the ochronosis or rebound hyperpigmentation risks associated with prolonged Hydroquinone use. The Fruit AHA component provides progressive surface exfoliation, accelerating the removal of existing hyperpigmented cells.

Q4. Can Melarid-TRX Serum be used in both morning and evening routines?
A4. Yes — Melarid-TRX is designed for AM and PM use. In the morning, follow with a broad-spectrum SPF 30 or above — particularly important because Tranexamic Acid targets UV-triggered pigmentation pathways, making sun protection a synergistic part of the treatment, not an afterthought. AHAs in the formula also increase photosensitivity. In the evening, apply after cleansing and before moisturiser. If using Retinol at night, alternate Retinol nights with Melarid-TRX nights rather than layering all actives simultaneously.

Q5. How do the Fruit AHAs in Melarid-TRX help the other brightening ingredients work better?
A5. The Fruit AHAs (Alpha Hydroxy Acids derived from natural fruit sources) in Melarid-TRX serve two complementary roles. First, they dissolve the desmosomes binding hyperpigmented cells to the surface, accelerating their shedding and visibly brightening skin tone faster than the depigmenting actives alone. Second, by removing the compacted outer layers of the stratum corneum, they improve the penetration of Tranexamic Acid, Kojic Acid, Alpha Arbutin, and Niacinamide into the viable epidermis where these actives need to reach to inhibit tyrosinase and melanosome transfer — making the entire formula work more efficiently.
