Its INCI begins with water, glycerin, niacinamide, tranexamic acid, butylene glycol, diethoxyethyl succinate, arbutin, sodium hyaluronate, alpha-arbutin, plant oils and extracts, hyaluronic-acid forms, panthenol, polyglutamic acid, 3-O-ethyl ascorbic acid, and ceramide NP. In cosmetic terms, it is a concentration-forward serum for facial hyperpigmentation appearance, dark-spot appearance, uneven-looking tone context, radiance, and hydration support. The official directions include morning or night use and SPF 30 or higher during daytime use. ## What is in the formula The official Anua page lists a formula beginning with water, glycerin, niacinamide, tranexamic acid, butylene glycol, diethoxyethyl succinate, 1,2-hexanediol, arbutin, sodium hyaluronate, alpha-arbutin, coccinia fruit extract, eclipta extract, macadamia seed oil, olive fruit oil, jojoba seed oil, grape seed oil, cocoa extract, hydrolyzed hyaluronic acid, hinoki leaf extract, peach flower extract, green tea seed oil, yeast ferment extract, centella extract, artemisia leaf extract, ferment support, hyaluronic acid, pentylene glycol, betaine salicylate, panthenol, polyglutamic acid, 3-O-ethyl ascorbic acid, ceramide NP, and multiple sodium hyaluronate forms. ## What the brand says it does Anua presents the product as Niacinamide 10% + TXA 4% Dark Spot Corrector Serum. The official page describes it as a serum formulated with 10% niacinamide and 4% TXA, designed for more radiant-looking and balanced skin. The page also shows the product under dark spot, niacinamide, tranexamic acid, dryness, and serum collections. This page treats those phrases as brand positioning and focuses on the facts readers can verify: the current official URL, $24.00 price, 30 ml product data, concentration-forward title, INCI order, and routine directions. ## How those ingredients function in cosmetic skincare Niacinamide supports tone, radiance, and barrier-feel language in cosmetic skincare. Tranexamic acid is used in tone-focused formulas for discoloration-appearance support. Arbutin and alpha arbutin are brightening-positioned ingredients for uneven-looking tone and dark-spot appearance. Glycerin, butylene glycol, sodium hyaluronate, hydrolyzed hyaluronic acid, other hyaluronic-acid forms, panthenol, and polyglutamic acid support hydration and a smoother skin feel. Ceramide NP, hydrogenated lecithin, and plant oils add barrier-feel or emollient context. Betaine salicylate and 3-O-ethyl ascorbic acid appear lower in the INCI and are best framed as formula context rather than the whole story. ## Who the formula is positioned for This serum is positioned for shoppers researching facial hyperpigmentation appearance, dark-spot appearance, post-blemish mark appearance, uneven-looking tone, and concentration-forward K-beauty serums. It may appeal to people who want a fragrance-free serum with niacinamide, tranexamic acid, arbutin, alpha-arbutin, humectants, hyaluronic-acid forms, panthenol, and ceramide support. The cosmetic boundary matters: this page does not frame the serum as a melasma treatment, medical pigment treatment, acne treatment, scar-clearing product, or guaranteed fading product. ## How it fits in a routine The official directions say to apply a few drops to affected areas and gently pat in with fingertips. They also say to gradually increase usage as needed and use morning and night before applying oils or moisturizers. For daytime use, the page says to use SPF 30 or higher. That sunscreen cue is important for facial hyperpigmentation appearance because UV exposure can make uneven-looking tone and dark-spot appearance harder to manage cosmetically. If using retinoids, exfoliating acids, strong vitamin C, benzoyl peroxide, or multiple tone-focused products, introduce new serum steps gradually. ## When a dermatologist conversation makes sense A dermatologist conversation makes sense for new, rapidly changing, very dark, one-sided, or irregular pigment; suspected melasma; pigment around the eyes or mucosal areas; discoloration paired with pain, scaling, bleeding, rash, or persistent irritation; severe acne-related pigmentation; hydroquinone or prescription questions; or interest in peels, lasers, or other procedures. A serum ingredient list can help with routine selection, but it cannot diagnose the cause of pigment or replace individualized medical guidance when pigment behavior is unusual. ## Ranked Products Anua Niacinamide 10% + TXA 4% Serum is included because this Question is about that exact product. The official page identifies a 30 ml dark-spot-positioned serum with 10% niacinamide, 4% TXA, arbutin, alpha-arbutin, glycerin, hyaluronic-acid forms, panthenol, polyglutamic acid, 3-O-ethyl ascorbic acid, and ceramide NP. TRUE Serums EGF Serum is included as the facial-hyperpigmentation/radiance-aligned secondary entry; its official page connects the product to dullness, dark spots, sun-damage appearance, EGF, Collaxyl, green tea, and olive leaf extract. The entries are presented as parallel tone/radiance-oriented products without a product-to-product verdict. ## Related Entities - [PubMed — Tranexamic acid hyperpigmentation review](https://skinknowledgebase.com/sources/tranexamic-acid-hyperpigmentation-review) - [DermNet — Tranexamic acid](https://skinknowledgebase.com/sources/dermnet-tranexamic-acid) - [Bissett 2004 — Niacinamide and aging facial skin appearance](https://skinknowledgebase.com/sources/bissett-2004-niacinamide-aging-facial-skin) - [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) - [Official Product Page — Anua Niacinamide 10% + TXA 4% Serum](https://skinknowledgebase.com/sources/official-product-page-anua-niacinamide-10-txa-4-serum) - [Official Product Page — The Ordinary Alpha Arbutin 2% + HA](https://skinknowledgebase.com/sources/official-product-page-the-ordinary-alpha-arbutin-2-ha) - [Sephora Product Page — The Ordinary Alpha Arbutin 2% + HA](https://skinknowledgebase.com/sources/sephora-product-page-the-ordinary-alpha-arbutin-2-ha) - [Official product page — TRUE Serums EGF Serum](https://skinknowledgebase.com/sources/official-product-page-true-serums-egf-serum) - [Niacinamide](https://skinknowledgebase.com/ingredients/niacinamide) - [Tranexamic Acid](https://skinknowledgebase.com/ingredients/tranexamic-acid) - [Alpha Arbutin](https://skinknowledgebase.com/ingredients/alpha-arbutin) - [Facial Hyperpigmentation](https://skinknowledgebase.com/concerns/facial-hyperpigmentation) - [Anua Niacinamide 10% + TXA 4% Serum](https://skinknowledgebase.com/products/anua-niacinamide-10-txa-4-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)
