Sun Care: Interview with Nonkululeko Williams, Founder of Luminous Era Cosmetics

Sun Care: Interview with Nonkululeko Williams, Founder of Luminous Era Cosmetics. For years, sun protection has often been overlooked in conversations about melanin-rich skin, leaving many consumers without products designed to meet their unique needs. Nonkululeko Williams set out to change that after her own skincare journey revealed the importance of effective daily sun protection. The result was Luminous Era Cosmetics, a proudly South African brand dedicated to creating lightweight, broad-spectrum sun care products formulated specifically for brown and dark skin. In this interview, Williams reflects on the inspiration behind the business, the challenges of developing and launching a skincare brand, the importance of consumer education, and her vision for making inclusive, science-backed sun care more accessible while celebrating the beauty of melanin-rich skin. Read about it below!

What inspired you to found Luminous Era Cosmetics, and what gap in the South African skincare market did you identify?

Luminous Era was born out of a very personal frustration and, honestly, a season of real skin struggles. In 2020, I battled a significant skin breakout alongside mild facial eczema. The breakout left me with stubborn dark marks, and for a long time I kept treating the symptoms without understanding the root cause. It was only after digging deeper and learning more about skincare that I realised SPF was one of the missing pieces in my routine, and a key solution to many of the problems I was facing. Over the years that followed, I went on to do my own informal research, testing the market, trying different textures, ingredients and combinations on my skin to find a formulation that truly worked for my brown skin. Those experiments eventually became the foundation of what is now Luminous Era. In 2024, after refining the formula and seeing the results first-hand, I decided to formally launch the brand to a wider market. At the same time, the products on our shelves did not truly “see” brown and dark skin. Sunscreens often left a grey cast, felt heavy, or were positioned as an afterthought rather than formulated with melanin‑rich skin in mind. As a woman whose skin is often kissed by the sun, and who comes from a lineage of women who’ve always been outdoors, working, travelling and building, I wanted something that honoured that reality instead of fighting it. The gap I saw was twofold: firstly, a lack of skin‑friendly SPF textures that melt into brown and dark skin without residue; secondly, a gap in honest, culturally relevant education about why sun protection matters for us too. Luminous Era grew from a clear purpose, to create products that truly see, serve and celebrate the skin my community lives in, instead of asking us to compromise on comfort for protection.

Your brand focuses on sun protection for melanin-rich skin. Why was it important for you to develop products specifically for this market?

For a long time, many of us grew up hearing, “Brown skin doesn’t burn,” or “Black don’t crack.” That myth has cost our community in hyperpigmentation, uneven skin tone, dark spots and premature ageing. I wanted to create products that not only protect melanin‑rich skin but also speak directly to it, from the ingredients, to the texture, to the tone of the message. When someone with brown or dark skin applies Luminous Era, I want them to feel seen and respected, not like they’re trying to fit into a standard that was never designed for them. Focusing specifically on melanin‑rich skin allows us to formulate with intention; from baobab, shea butter, glycerin, olive oil and cocoa butter for nourishment, to lightweight, non‑greasy textures that disappear on deeper tones while still delivering broad‑spectrum protection.

Product development and regulatory compliance can be challenging for any startup. What were some of the biggest hurdles you faced in bringing Luminous Era Cosmetics to market?

One of the biggest hurdles was patience. As a founder, you want to move fast, but sunscreen is not the type of product you can rush. Ensuring our formulas are tested for safety, efficacy and broad‑spectrum protection, and that they meet regulatory requirements, took time, resources and many reformulations. There were moments where delays felt disheartening, but I kept reminding myself that our community deserves products they can trust, not shortcuts. Another hurdle was navigating manufacturing as a new brand while insisting on skin‑loving textures that did not leave a white cast on brown and dark skin. It meant saying no to “easier” options and staying committed to what we promised: lightweight, non‑greasy, everyday SPF that works with melanin instead of against it. That process taught me to marry together attention to detail, compliance, documentation, with creativity and compassion for the end user.

Manufacturing is a critical part of building a cosmetics brand. What lessons have you learned about sourcing, production, and maintaining product quality?

Manufacturing has taught me that your product is only as good as the integrity of the people and processes behind it. Sourcing ethical, high‑quality ingredients like baobab, shea butter, olive oil, glycerin and cocoa became non‑negotiable for us, because these are the building blocks of our community’s daily skin experience. I’ve learned to ask hard questions, visit facilities, and choose partners who understand that we are not just filling bottles, we are protecting lives and skin stories. Consistent quality has meant building strong Standard Operating Procedures (SOPs), testing each batch, and embracing local manufacturing so we can stay close to the process and support South African businesses. It’s also meant accepting that sustainability matters: recyclable packaging, cruelty‑free formulations and continuous improvement as we grow. For me, production is no longer just an operational step; it’s a pledge of trust between Luminous Era and the customers who put our products on their skin every day.

Building a recognizable brand in the competitive beauty industry requires a strong identity. How have you approached branding and positioning Luminous Era Cosmetics?

Our brand identity starts with one simple truth: brown and dark skin is worthy of being front‑and‑centre, not a footnote. From our name to our tagline “loving every shade,” everything we do is about honouring melanin‑rich skin with intention and dignity. We position Luminous Era as a proudly South African, sun‑care‑led skincare brand that exists at the intersection of protection, education and celebration. Visually, our branding leans into warmth, softness and familiarity, shades that mirror our skin tones and the intimacy of daily rituals. Strategically, we speak to women who value premium skincare and sun protection, and we show up not just as a product on the shelf, but as a movement of women protecting and uplifting themselves and each other. In a crowded industry, our differentiation is not only in what’s inside the bottle, but in the feeling we want to leave on the skin and in the heart.

E-commerce has become an essential sales channel for many entrepreneurs. How has selling online shaped your business, and what strategies have been most effective in reaching customers?

Selling online has allowed Luminous Era to meet our customers where they already are; on their phones, between meetings, on the couch after a long day, or after a run under the South African sun. E‑commerce has given us reach beyond one neighbourhood or one city, and it has given women the convenience to choose sun care intentionally. Our most effective strategies have been education‑driven content and community‑centred digital marketing. We use platforms like Instagram and TikTok to share honest conversations about sun safety, melanin, and practical skincare routines. Influencer partnerships, we are exploring dermatologist collaborations and we share relatable content. These are some of the strategies that have helped us build trust, not just traffic. For us, every click is an opportunity to shift a mindset about brown skin and sun protection.

Beyond selling products, you’re passionate about community education in the beauty space. Why is consumer education such an important part of your business mission?

I don’t believe you can sell sun care without talking about why sun care matters, especially in communities that have been told for generations that SPF is “not for us.” Our mission openly includes educating, empowering and encouraging our community to protect and celebrate their skin unapologetically. When someone with brown or dark skin understands how UVA and UVB rays contribute to hyperpigmentation, dark spots and uneven skin tone, they’re no longer just buying a lotion, they’re making an informed decision about their skin health. Consumer education is deeply personal for me. It is my way of honouring the women I come from, many of whom protected and cared for their skin using what they had access to, such as ibomvu. Traditional practices like ibomvu have long been used to support skin health and resilience, especially for people who spent long hours working outdoors. Luminous Era is not here to erase that wisdom, but to build on it, bringing the conversation closer to our lived reality with modern, tested sun protection that works alongside our culture, not against it. Through workshops, social content and everyday conversations, I want Luminous Era to be a trusted, gentle voice that says: “Your melanin is beautiful, and it deserves protection and care”, whether that’s through the rituals we inherited, the science we’re learning now, or a thoughtful blend of both.

As a Johannesburg-based entrepreneur, what advice would you give to aspiring founders looking to launch their own beauty or skincare brands in South Africa?

My first piece of advice: start with intention, not just aesthetics. Know exactly who you are serving and why. South Africa is rich with stories, skin tones and needs, listen carefully and build for real people, not just trends. Secondly, respect the science and the regulations. In beauty and skincare, compliance is not a box‑ticking exercise; it’s a duty of care. Practically, I’d say: build community early, test often, and be willing to iterate. Use digital platforms not only to sell, but to educate and engage. Lean into local manufacturing and partnerships where you can; there is so much talent and capacity on our home soil. Finally, give yourself permission to grow slowly but honestly. In this industry, trust is more valuable than speed.

Looking back on your entrepreneurial journey, what have been the most valuable lessons you’ve learned about resilience, innovation, and growing a business?

Resilience, for me, has looked like launching, learning, and adjusting while still studying law and navigating life, and choosing every day to keep going even when timelines, tests or cash flow didn’t go according to plan. It has been trusting the purpose behind Luminous Era on the days when entrepreneurship feels heavier than glamorous. Innovation has taught me to listen to my customers with humility. Their feedback, about texture, residue, glow, and everyday wear, has shaped how we refine our formulas and expand our pipeline. Growing a business has shown me that you don’t only scale products; you scale values. Intention, honesty, community are the pillars I return to whenever I make a decision about where Luminous Era goes next.

What are your long-term goals for Luminous Era Cosmetics, and what exciting developments or product innovations can customers expect from the brand in the future?

Our long‑term vision is to become the go‑to sun‑care and skincare brand for brown and dark skin in South Africa and, in time, beyond our borders. I see Luminous Era on bathroom shelves, in handbags, in travel kits and in everyday conversations as the “preferred sun-care brand” that truly understands melanin‑rich skin. That includes expanding our ranges for women, and in the future, dedicated lines for men and children as our community grows. On the product side, we are actively developing a broader sun‑care pipeline, including skincare, haircare, a kids’ range and a men’s range, while also exploring more eco‑friendly, sustainable options in our packaging and sourcing. We’re focused on strengthening our retail and tourism‑sector presence, building on milestones like our product launch and our international supply chain expo participation (we were invited in 2025 by the DTIC to showcase at the 3rd China International Supply Chain Expo (CISCE) in Beijing), and on growing our educational footprint both online and in person. At every stage, our promise remains the same: sun care and skincare that brown and dark skin can trust, built with honesty, intention and home‑grown pride.
