Company profile
researched Sep 2026OSAZ (Osazomon) is a beauty-technology company founded by scientist and engineer Osazomon Imarenezor that develops personalized skincare for melanin-rich skin using artificial intelligence and skin data. Its consumer offering centers on what the founder calls the "holy trinity" of dermatology rather than serums and cleansers: a retinoic acid anti-aging cream (OSAZ RENEW), a hyperpigmentation cream with antioxidants formulated with Cysteamine Hydrochloride and retinoic acid (OSAZ GONE), and a mineral sunscreen. Product listings on the company site include TINT Sunscreen, a TINT Sample Shade Kit, SunSeal Moisturizing SPF 30+ Lip Balm, SunGlaze Hydrating SPF 30+ Lip Gloss, and an SPF Ultra Lip Kit Duo, priced in Nigerian naira. TINT is described as a buildable, non-comedogenic, long-wearing tinted formula with 25% zinc oxide providing UVA/UVB protection and up to 12-hour wear.
Customers begin with a three-step flow: taking a selfie, describing their skin type and concerns, and receiving a tailored routine. The company's AI shade-matching system analyzes an uploaded photo in natural lighting to determine undertones and recommend a TINT match, while its personalization model analyzes medical-grade assessments to recommend regimens and adjust active ingredients for factors such as dryness, keloids, eczema, oiliness preference and climate. Alongside the direct-to-consumer line, OSAZ has developed a proprietary Formulation as a Service (FaaS) platform, a B2B SaaS product for beauty and pharmaceutical brands intended to streamline product development, optimize customer experience and improve demand forecasting for multicultural markets.
Subscribers receive discounts (10% off a first order, with subscriber discounts and free shipping on subscription orders advertised on the site), 30-day free returns, and access to a dermatology provider by message. The free skin survey is offered to subscribers who do not purchase, both as a consumer service and as a source of customer-interest data.
Founding story
Founder Osazomon Imarenezor was born and raised in South Chicagoland to Nigerian immigrant parents. Her interest began in high school, where she used pH strips from the chemistry lab to make her own leave-in conditioner; she went on to research skin cells and was published in 2015. In 2016 she joined an accelerator program and launched a first beauty-tech startup, Slay Beauty, a booking app for beauty services, with $10,000. After that business lost traction and funding did not materialize, she pivoted. She had begun a PhD in Biomedical Sciences before leaving the program with a Master's degree, and conducted a two-year comparison of West African and U.S. skin diseases over the previous 20 years, which revealed a lack of data and of effective solutions for melanin-rich skin, including a shortage of sunscreens across a wide range of skin tones. Combined with her observation of U.S. demographic shifts and her experimentation with a skincare API, this became the basis for OSAZ, reported as launched in 2022.
Business model
OSAZ sells skincare and sun-protection products directly to consumers online, with a subscription option carrying discounts, free shipping and access to a dermatology provider, and limits purchases to one product per customer so that subscribers gain a discount and access to personalized products. In parallel it has built a Formulation as a Service (FaaS) B2B SaaS platform licensed to beauty and pharmaceutical brands for product development, customer-experience optimization and demand forecasting.
Revenue comes from e-commerce sales of skincare and SPF products (priced in Nigerian naira on the site, e.g. TINT Sunscreen at ₦35,990 and SunSeal SPF 30+ Lip Balm at ₦4,500), recurring subscription orders with a 15% subscriber discount, and a B2B software-as-a-service Formulation as a Service platform for brands.
Traction
Coverage from August 2025 reports three products on the main webpage, with the Osaz Tinted Sunscreen for sale and the others sold out, and a subscription model that limits customers to one product purchase. The site publishes customer reviews for TINT Sunscreen, GONE Cream and RENEW Cream. The company reports early product successes including a complexion-friendly mineral SPF, a 5% Cysteamine Hydrochloride dark spot cream and a retinoic acid anti-aging cream, and secured a Techstars partnership in 2024.
Latest developments
An August 2025 profile reported that the Osaz Tinted Sunscreen was the only product then available for purchase on the main webpage, with the remaining products sold out, and described the company's free skin survey for subscribers who do not buy. Following its 2024 Techstars partnership, the company has been organizing beauty-tech hackathons in the U.S. and Nigeria with a prize pool of over 12.5 million naira.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
OSAZ positions itself as a data-driven beauty-tech entrant serving underrepresented skin types in an industry that has relied on broad-stroke solutions. Press coverage places it alongside larger AI beauty efforts such as Sephora's Smart Skin Scan and Unilever's Beauty Hub Pro, with OSAZ differentiating on medical assessments, shade matching and customized ingredient lists. At the time of August 2025 coverage, the Osaz Tinted Sunscreen was the only product available for sale on the main webpage, with the others sold out.
The company's stated differentiator is training its models specifically on data from melanin-rich skin, an area the founder identifies as scarce and poorly annotated in existing datasets, which are largely oriented to non-melanin-rich skin and not focused on skin health. Rather than a broad catalog, OSAZ deliberately avoids serums and cleansers and concentrates on three dermatology staples — retinoic acid, an antioxidant hyperpigmentation cream, and sunscreen — arguing that a 15-step routine is unnecessary. Its tinted mineral SPF is formulated to blend into deeper complexions, and it offers both consumer personalization and a B2B formulation platform.
Technology
OSAZ's AI model is trained on populations with melanin-rich skin, including Asian, Black and Latin American consumers, drawing on dermatologist medical assessments, clinical studies, dermatology research, Reddit reviews and user feedback. The model takes a dermatologist assessment, analyzes it and generates solutions tailored to a user's skin type and lifestyle, selecting or excluding active ingredients based on conditions such as dry skin, keloids or eczema, personal preferences such as avoiding oily sunscreen, and environmental factors, since a sunscreen suited to Australia may not suit Alaska. A separate AI shade-matching system analyzes undertones from an uploaded photo to recommend a TINT shade. The company also operates a Formulation as a Service platform that applies AI and data analytics to brand product development.
Go-to-market
OSAZ sells through its own website with a selfie-based skin assessment and shade-matching funnel that converts visitors into subscribers, offering 10% off a first order to community sign-ups and using a free skin survey to capture interest from non-purchasers. Awareness has been built through founder-led press coverage in Nigerian and African technology and business media and through an accelerator partnership; the company also organizes beauty-tech hackathons in the U.S. and Nigeria with a prize pool of over 12.5 million naira.
Consumers with melanin-rich skin, including lighter skin tones of people of color, who have been underserved by mainstream sunscreen and skincare ranges, with concerns such as hyperpigmentation, uneven tone, texture, aging and acne; the founder also cites underrepresented communities across Africa, Brazil and India. The FaaS platform targets beauty and pharmaceutical brands developing products for multicultural markets.
Geography
OSAZ operates from a U.S. base, with the founder's work spanning Chicago, Miami and Lagos, and lists a U.S. support text line plus a Nigerian phone number for customers. With Techstars' support the company has been expanding from the U.S. to Lagos, Nigeria, and targeting underrepresented communities in Africa, Brazil and India. Site pricing is displayed in Nigerian naira.
History
OSAZ was launched in 2022 with a mission to close the gap in solutions for melanin-rich skin using AI-powered personalized formulations. After an initial rejection, the company secured a Techstars sponsorship and partnership in 2024, announced in October 2024, bringing funding and access to an advisor and investor network. Early products included a complexion-friendly mineral SPF, a dark spot cream with 5% Cysteamine Hydrochloride and an anti-aging retinoic acid cream. By August 2025 the company's site listed three core products, with the tinted sunscreen for sale and the others sold out, alongside SPF lip products.
Risks & controversies
The founder has described difficulty raising funding for her earlier venture and the hurdles of building as a Black female founder in an industry where representation is limited. The consumer business depends on a narrow product range, and as of August 2025 most listed products were sold out, leaving one item for sale.
