BTB13

BTB13 is a Finnish professional skincare brand founded in 2012 and owned by Berner Oy, the Helsinki-based company that develops and distributes it [2][5]. The range is built around a patented antioxidant compound, also called BTB13, and is sold mainly through professional salon and clinic channels rather than to consumers directly. Its products are developed and manufactured in the Herttoniemi district of Helsinki [1].

The brand presents itself as a medical-grade series for treating common and demanding skin concerns. According to the company, it is "a medical professional cosmetics series developed to effectively address common skin challenges while supporting skin wellness," and it uses the tagline "This is your skin confidence."

BTB13 grew out of a Finnish biotechnology innovation rather than from a named founder. The company traces its origin to a biotech research group based in Oulu that developed a skin-treating and protecting compound, which became the BTB13 compound at the centre of the line [6]. No individual founder is named in the brand's own materials; the line is presented as a corporate development under Berner Oy.

The name itself encodes the compound's two defining ingredients. The company explains that "BT" stands for L-carnitine, which it says supports the skin's natural metabolism, and "B13" stands for orotic acid, which it describes as taking part in the skin's natural renewal process [2].

BTB13 is owned and operated by Berner Oy, a Finnish company headquartered at Sahaajankatu 20–22 in Helsinki [4]. Within Berner's professional cosmetics portfolio, BTB13 is presented as one of three in-house professional brands, alongside Ekopharma and Unna Nordic, all sold through Berner's business-to-business shop [5]. The products are distributed through professional channels and Berner's online store.

The line spans several product families, including Intense Hydration, Pro-Age, Skin Relief, Skin Glow and Hair Growth, with product types ranging from cleansers, toners, serums and face creams to masks, exfoliants, eye creams, sunscreens, and hair and lash products. Berner's professional catalogue also lists body, makeup and sunscreen products under the brand, so its scope reaches beyond facial skincare into makeup and haircare.

At the core of the range is the BTB13 compound, described by the company as a patented, antioxidant-rich Finnish innovation. Sources differ slightly on its makeup. The brand's own about page frames the compound around two actives — L-carnitine and orotic acid — which give the brand its name [2], while Berner and other distributor descriptions describe it as a chemical compound consisting of three components: orotic acid, L-carnitine and hyaluronic acid [6]. The two accounts are complementary rather than contradictory, with hyaluronic acid named as an additional active in the broader formulations. Beyond the signature compound, the products draw on ingredients such as hyaluronic acid, sodium PCA, panthenol, allantoin, vitamin E, ceramides and prebiotics.

Berner states that the compound is widely patented and that it has been shown to protect cells from harmful oxygen radicals, attributing its development to the Oulu research group [6]. The brand uses the compound across both its retail products and its in-salon treatments.

The treatment side of the brand is delivered in professional settings by trained cosmetologists [3]. These services include BTB13 Skin Therapy, a tailored facial; a Medical Skin Peel that the brand says renews the skin surface and can reduce the visibility of age changes and excess pigmentation; and a Micro-Meso Therapy combining microneedling with mesotherapy to help active ingredients penetrate more deeply.

BTB13 is active. Its brand site remains live with current product lines and treatments, and the products are sold through Berner's professional business-to-business shop. The brand's social accounts on Instagram and Facebook are maintained under the handle @btb13skincare. Its distribution appears focused on Finland, through a professional and salon channel.
