Day+

Day+ is a French beauty brand founded in Paris in 2018 by Claire Despagne [5]. It began with a single product: a drinkable collagen stick combining marine collagen and spirulina, sold as a daily "beauty shot." That stick remains the brand's signature item, and the wider range has since grown to include facial serums, sun-protection drops, eye patches, masks and Gua Sha tools.

The name can be confusing, because Day+ sits inside a larger structure. According to the company, "D+ for Care" is the parent brand and Day+ is its flagship product line, launched as the company's first offering [5]. The two names appear across related web domains for the same business. This article treats Day+ as the brand, in line with how it is listed by retailers.

Claire Despagne worked in finance before starting the company. The brand's account describes a founder who personally took several beauty supplements for years and grew tired of mixing capsules, tablets and powders every day; she set out to replace that routine with one drinkable product [5]. The result was the Day+ collagen stick, which the company says launched in March 2018 as its first product [6].

Despagne has summarised the founding idea as a refusal to compromise: in the brand's words, "a formula should never choose between clinical efficacy and user experience." From the start the company positioned itself around combining measurable results with an enjoyable daily ritual.

Day+ frames its outlook as "funky science," a phrase the founder uses to describe blending scientific rigour with lifestyle and originality. In an interview published by the company, Despagne calls it "more than a wellness solution… an attitude, an originality, a state of mind." The brand presents itself as "edgy, expert, free and unique," and says its goal is to add "a little magic" to everyday routines.

The positioning spans two areas: ingestible "nutricosmetics" such as collagen and spirulina supplements, and a topical cosmetics line of serums, sun care and masks. The company emphasises transparency of formulas and natural-origin ingredients made in France.

The drinkable Collagen & Spirulina+ Shot is the brand's best-known product and its top seller on its own store [1]. The company describes the formula as marine collagen combined with spirulina and states it is clinically proven for skin-quality benefits [5]. Other named products include Glow Drops SPF 50 sun-protection drops, a Plumping Lip Serum with peptides that the brand says increase lip volume by 40%, and anti-aging eye patches.

Day+ says each formula goes through more than 120 tests and an 18-to-24-month development cycle, developed with French laboratories and dermatological experts [3]. Manufacturing is split by product type: cosmetics and food supplements in France, packaging in France, Belgium and Italy, and accessories in China and Morocco [3].

On its corporate-responsibility page, the company says its products are developed and manufactured in France, with raw materials it describes as carefully sourced. Packaging is stated to be made in Europe, recycled and recyclable, and FSC-labelled [3]. The brand also references cruelty-free and non-GMO practices, though the packet records no formal third-party certifications.

Day+ began as a direct-to-consumer brand selling through its own website. In 2021 the company expanded into wider retail, reaching Sephora, Galeries Lafayette, Monoprix and pharmacies in France [8]. The brand ships internationally, including to Nordic markets, but its primary market remains France.

The brand's UV Drops SPF 50 was named "Product Care of the Year" at Beautyworld Middle East in 2024 [2]. Day+ has also been featured in French editorial coverage of drinkable collagen and anti-aging products, including Vogue France, Harper's Bazaar France, Cosmopolitan and Elle, according to mentions the company lists on its own press page [4]. As these citations are compiled by the brand, the publication names and dates are verifiable but the framing is the company's own.

Day+ is an actively trading brand. Its most recent recorded activity is a March 2025 feature in French Vogue, alongside an ongoing product line and continued retail distribution [4]. The company operates chiefly in France, with international shipping through its English-language site and retailer listings.
