Dr. Reju-All

Dr. Reju-All is a South Korean skincare brand operated from Seoul's Gangnam district by Neo Simplix Co., Ltd. [2] It belongs to the wave of "K-pharmacy" skincare lines built around clinically studied actives, and centres much of its range on PDRN, a salmon-derived ingredient that became a prominent K-beauty trend in the mid-2020s. According to the company, it was founded by licensed pharmacists and doctors, whose individual names it does not disclose [12], and it sells chiefly through pharmacies and clinics rather than conventional beauty retail.

The brand is recent. Its Korean telecommunications sales registration is dated 2025 [2], and the earliest editorial mentions it lists run from December 2025. It remains active, operating two direct-to-consumer stores — a Korean domestic site (drreju-all.kr) and an English-language global store (drrejuall.com) — with customer reviews posted into mid-2026.

Dr. Reju-All presents itself as a brand created by doctors and pharmacists to address three problems it identifies in the skincare market: product development it says lacks genuine expertise, sales prioritised over consumer education, and packaging built around visuals rather than guidance. A K-beauty retailer describes it, in the brand's own words, as "a derma brand founded by licensed pharmacists and doctors" that aims to "fix ingredient myths in the beauty market." A recurring line in the company's own copy frames the positioning: "We're not here to create viral moments. We're here to create products that actually change your skin."

The corporate entity behind the brand, Neo Simplix Co., Ltd. (네오심플릭스), is registered in Gangnam-gu, Seoul, with Jung Jun-ho listed as representative [2]. Dr. Reju-All has also explained its name as a combination of dermatological expertise ("Dr.") and broad recovery, stating elsewhere that "Rejuall stands for 'Rejuvenate from all damage'" [7].

Dr. Reju-All's Korean company information lists its legal operator as Neo Simplix Co., Ltd. [2]. An independent review by aesthetic dermatologist Dr. Rachel Ho instead names the manufacturer as "Rejouviance" [11]. The discrepancy is unresolved in public sources: the Neo Simplix name comes from the brand's own legal registration and is the more authoritative source for this kind of fact, while the alternative appears only in the third-party review and may reflect a manufacturing or original-equipment arrangement rather than the brand's corporate owner.

The brand positions itself around precision dosing rather than the high ingredient percentages often used in marketing. On its science page the company states that "every ingredient is chosen at optimal concentrations, prescribed with precision, and delivers results you can feel," and frames its approach as a correction to industry misinformation. That thinking carries into a pharmacy-channel model the company says is designed so products are recommended with professional input, and into a "prescription-style" presentation. The brand markets a labelling system it calls the Dr.Reju-All Skin Code, described as indicating what each formula does, when to use it, and how it works. Its tagline, "Korea's No.1 Pharmacy Skincare Brand," is a self-description rather than an independently verified ranking.

The range is concentrated in skincare: PDRN creams, serums, barrier creams, sheet masks, and scalp and lip serums. Signature products named by the brand include the Advanced PDRN Rejuvenating Cream, the Advanced LC-Ceramide Barrier Cream, the Advanced Retino-Mela Serum, aimed at dark spots, the Advanced PDRN Rejuvenating Mask, and the Advanced PDRN Hair Density Scalp Serum. The Korean catalogue also lists products built on PDLLA, a poly-lactic-acid firming technology, and a retinol line.

Several active ingredients anchor the formulations. The company describes its PDRN — polydeoxyribonucleotide, derived from salmon DNA — at a concentration of 1,200 ppm and 99% purity, with a micro-molecular size it says aids penetration [7]. It pairs this with HPR (hydroxypinacolone retinoate), which it presents as a next-generation retinoid roughly 30 times more stable than conventional retinol, and an LC-Ceramide (long-chain) formulation it calls patented and "skin-identical" in structure. Copper peptide, exosome technology, niacinamide and D-panthenol appear across individual products.

A number of efficacy claims come from the company's own materials. It says a single application of its PDRN cream following laser treatment improved skin recovery and soothing "by over 25%," that HPR showed "0% irritation in clinical trials" and suits retinoid beginners, and that its LC-Ceramide is a "90%+ match to natural skin ceramides." The brand further states that its products were rated "Excellent" for skin compatibility by Germany's Dermatest, with a "0.00 irritation index," and reports sales of more than four million units worldwide [7]. These figures are brand-stated and have not been independently verified. On formulation, the company says it manufactures to pharmaceutical-grade standards in South Korea and excludes parabens, sulfates, phthalates and a list it gives variously as 80-plus or 82-plus substances drawn from global regulatory exclusion lists.

An independent assessment offers a counterweight to these claims. Reviewing the PDRN cream, Dr. Rachel Ho found it lightweight, with good spreadability, and noted that it soothed redness quickly; she also reported, however, that topical PDRN creams "did not replicate injectable PDRN benefits," observing no visible improvement in pore size or wrinkle depth [11]. She suggested the product suits normal-to-oily skin.

Dr. Reju-All maintains a curated press page listing third-party editorial mentions from late 2025 and early 2026, including Vogue, Harper's Bazaar, Bustle, the New York Post, E! News and BuzzFeed [10]. Vogue's "7 K-Beauty Trends Shaping 2026" cited PDRN and exosomes as ingredients moving into consumer formats, and a December 2025 Vogue retrospective noted the brand's clinically optimised concentration approach. These appearances are listed by the company itself, and several are product round-ups in which it is one of many entries.

Dr. Reju-All is an active brand. Its Korean and global direct-to-consumer stores are operating, customer reviews continued to appear on its Korean product board into June 2026 [4], and its products are listed across international marketplaces including Amazon, Qoo10 and Rakuten. The brand describes its geographic reach inconsistently on its own site: the global store states a presence in "5,000+ pharmacies and clinics across 70+ countries" [7], while the science page gives "30+ countries" [9]. Both are brand claims, neither has been independently verified, and the brand is best described as operating across multiple regions rather than at a precise count.
