Winter skin survival: don't let the cold fool you -sunscreen is still a must
Image: Mikhail Nilov/pexels
July's skin health observances remind us that sun protection isn't seasonal, it's essential.
When the temperatures drop and the skies turn grey, it's easy to believe your skin is safe from the sun's rays.
Here's why your winter skincare routine needs a UV upgrade.
But winter is not a free pass to skip the sunscreen. July, with UV Safety Awareness Month, World Skin Health Day, and National Love Your Skin Day, offers the perfect reminder: there's no health without skin health.'Your skin is your body's largest organ. It protects you from the world, and yet we often forget to protect it back, especially when it's cold,' says Dr Cebi Sibisi, dermatologist and founder of Dr Cebi Dermatology.
'Sun protection should be part of your daily health routine, all year round.'The Invisible Winter RiskCold weather can be deceiving. Just because you don't feel the sun burning your skin doesn't mean it's not doing damage.
"Ultraviolet (UV) radiation remains a threat in winter, especially UVA rays, which account for 95% of the UV light that reaches the Earth and can penetrate clouds, windows, and even the top layer of your skin.
'UVA rays accelerate ageing by damaging collagen and elastin. UVB rays, which cause sunburn, may be less intense in winter, but they're still there,' explains Dr Sibisi. 'That's why a broad-spectrum SPF is non-negotiable, regardless of the season.'
A 2021 study published in the Journal of Clinical and Aesthetic Dermatology highlighted that cumulative exposure to UVA rays, even indoors or during overcast days, contributes significantly to premature ageing and pigmentation, especially in darker skin tones, where hyperpigmentation can be stubborn.

Sunscreen isn't just for summer or light skin
One of the biggest myths in skin care is that people with melanin-rich skin don't need sunscreen. While darker skin may offer some natural protection, it's not enough.
'Melanin filters out about 13.4% of UV rays,' says Sibisi. 'That's far from complete protection. In fact, skin cancer in darker skin tones is often diagnosed late, making it more dangerous.'
Pigmentation and melasma can worsen with sun exposure
Tinted sunscreens containing iron oxide offer an added layer of defence against visible light, a lesser-known skin enemy that can deepen dark spots.
Match your sunscreen to your skin type. We get it, sunscreen can feel greasy, heavy, or leave a ghostly cast. But not all sunscreens are created equal.

Just got inked? Essential aftercare tips to keep your tattoo looking amazing
What you need to know about aftercare and choosing the right design to keep your ink looking great. Image: Pexels/@Cottonbro Getting a tattoo is such a scary, exciting and personal experience. Whether you are adding to a growing sleeve collection or getting your first piece. Have you ever thought about what goes into caring for your tattoo? The work does not stop once the design is complete. Every tattoo artist will tell you that a fresh tattoo is an open wound and needs excellent care in the first few weeks to heal beautifully and maintain its detail. On platforms like TikTok, tattoo artists regularly share aftercare advice with their followers. They often stress that following the artist's instructions is a must. Here are some helpful tips from experienced tattoo artists: This often includes cleaning the tattooed area gently with fragrance-free soap, applying a thin layer of recommended ointment or lotion, avoiding direct sunlight and fragranced lotions. It's also important to resist the urge to scratch or pick at the tattoo as it heals. Yes, you'll feel the urge because it gets seriously itchy, but don't scratch! Just gently tap the itchy area instead. Several experts warn that skipping these steps can lead to fading, patchiness, or an infection. From my own experience with several tattoos and cover-ups, I know the process actually begins long before the needle touches your skin. Choosing the right design is crucial because, while a cover-up can be an option if you change your mind later, it is not always a perfect solution. The original tattoo's size, colour and placement can limit what is possible, and in many cases, the new design may have to be bigger or darker to hide the old one. Another factor that is often overlooked is the technique of the artist. A heavy-handed approach, where the needle goes too deep or the pressure applied is too strong, can cause excessive trauma to the skin. Even if you follow every aftercare instruction perfectly, a tattoo that's applied with too much force might take longer to heal, fade unevenly, or develop scarring, which can ruin its beauty altogether. This is why choosing an experienced and skilled tattoo artist is just as important as caring for the tattoo afterwards. It is also better to be certain about the design from the start. If you are unsure, start small with a tattoo that is easy to conceal. This allows you to see how you feel about having something permanent before committing to a large or highly visible piece. As much as tattoos are meaningful, they should still be fun and creative. However, they also don't always have to have a significant meaning behind them; sometimes you can get it because it was cute and it caught your eye, just be certain about it because it is permanent after all. There has to be a balance of excitement with proper planning as they can mark milestones, reflect your personality, make you look cool, or simply be art you love. Always conduct your own research before putting permanent ink on your body, and know what you're getting into. Make sure your tattoo remains something you will be proud to wear for years to come, even at 60.

Botox treatments in South Africa: what you need to know about safety
Botox is widely used as an anti-ageing treatment, but there are risks if patients opt for budget deals with unregistered clinics. Image: Cottonbro studio / Pexels A South African cosmetic treatment expert says there's no need for panic here following global concerns over a recent case in the United States where a woman was left partially paralysed after having routine botulinum toxin anti-ageing injections, commonly known as Botox. And while the mother of three survived from what doctors later said was a mild stroke, it set off warning bells among thousands of people who are increasingly turning to the treatment that targets facial muscles, tightens and rejuvenates the skin. Dr J D Erasmus, a general practitioner with a special interest in aesthetics and the Head of Aesthetics at the Longevity Centre at RXME, says fears of botulism from Botox injections are largely misplaced. Dr J D Erasmus says South Africans need to be more discerning when choosing where to have cosmetic treatments. Image: Supplied Video Player is loading.

Advertisement Next Stay Close ✕ 'People hear the word 'toxin' and understandably get nervous. But iatrogenic botulism (caused by a medical treatment) after aesthetic treatments is extremely rare in medical clinics with qualified doctors who follow proper protocols and only inject trusted products from regulated manufacturers,' he says. He adds that botulinum toxin is one of the most extensively studied anti-ageing treatments in aesthetic medicine. In addition to smoothing lines and wrinkles, the treatment is also known to relieve tension headaches. 'In cosmetic treatments, it's used in very small, highly controlled doses by trained professionals. When done correctly, it stays where it's injected, does its job, and your body naturally breaks it down over time. "The horror stories we hear are almost always linked to unqualified practitioners, dangerously high doses, and fake or unregistered products, and are not the work of reputable doctors in South Africa.' In cases of iatrogenic botulism from botulinum toxin injections, the toxin moves further than the treatment area and causes muscle weakness, which is an unusual complication rarely seen in aesthetic injections, he says. 'Globally, thousands of people undergo botulinum toxin procedures safely every day. According to our research, there have not been any recorded cases linked to aesthetic treatments in South Africa. 'Overseas, however, the risks increase where regulations are weaker. "In one extreme case in Turkey two years ago, 71 people developed iatrogenic botulism from botulinum toxin injections in just over a month, and 66 of those cases were traced to the same clinic." Erasmus says this latest scare highlights the dangers associated with medical or cosmetic tourism that's poorly regulated. 'You don't always know what product is being used, who is injecting it, or whether proper safety standards are being followed, and you can't always follow up with your practitioner if you have any concerns after the procedure. 'These types of incidents are important reminders to take your health seriously and choose a clinic you can trust. Before booking a treatment, check your practitioner's qualifications and reputation and make sure that the facility follows stringent product quality and safety regulations.'

Sip your way to wellness: how rooibos tea supports women at every age
What makes Rooibos stand out is its natural caffeine-free profile, low tannins, gentle effect on the stomach, and rich abundance of antioxidants all without additives. Image: Rahime Gül /pexels There's something deeply comforting about cradling a warm cup of tea, especially when it feels like life is moving a little too fast. And as we celebrate Women's Month in South Africa, it turns out that our go-to comfort drink, rooibos, is doing more than just calming nerves; it's quietly looking after women's health at every life stage. In a world of fancy supplements and wellness fads, rooibos is the low-key superhero sitting quietly in our kitchen cabinets. No hype, no additives, just a naturally caffeine-free herbal tea with proven health benefits, especially for women. The red brew with real benefits With over 22 million South Africans drinking tea daily, women remain the leading tea lovers, according to recent stats from Eighty20, a local data analytics firm. Rooibos, in particular, has grown in popularity as more women ditch high-caffeine, sugar-loaded drinks in favour of something gentler and more nourishing. 'Rooibos is more than just a traditional herbal tisane; it's a wellness companion for women at every stage of life,' says Professor Elmarie Terblanche of Stellenbosch University's Department of Exercise, Sport and Lifestyle Medicine. 'It's natural, caffeine-free composition aligns with women's evolving health needs, whether they're in school, navigating motherhood or managing menopause.' And it's not just anecdotal. A 2023 study in the Journal of Public Health in Africa found rooibos significantly improved lipid profiles, antioxidant status, and blood glucose control across a wide age range (6 to 83 years), including high-risk individuals.

Next Stay Close ✕ Research from prominent researchers highlights Rooibos' capacity to combat oxidative stress linked to chronic illnesses. Image: Nadin Sh/pexels From childhood to menopause Here's how rooibos supports women's health at every life stage: Girls (6–12 years) Rich in antioxidants for healthy development. Naturally sweet, no caffeine, low tannins, perfect for little ones. Doesn't interfere with iron absorption, which is vital during growth spurts. Teens and young women (13–25 years) Anti-inflammatory effects may ease menstrual discomfort. Helps with hydration and focus during exams or sports. Healthier swap for sugary sodas or hyper-caffeinated energy drinks. Women of reproductive age (26–40 years) Considered safe in pregnancy and breastfeeding (always check with your doctor). Supports heart health, blood sugar balance, and energy regulation. Caffeine-free means no spikes and crashes. Midlife and menopausal women (41–60+ years) Active compounds, such as aspalathin and nothofagin, assist in metabolic support. May reduce symptoms like hot flushes and fatigue. Supports cardiovascular wellness and helps reduce inflammation. Rooibos vs the world While South Africa celebrates its iconic rooibos, other cultures have their own wellness brews, and it's worth noting how they compare. Green tea in East Asia: Loved for centuries in China and Japan, green tea is known for its catechins, powerful antioxidants that promote fat burning and protect the brain. But green tea contains caffeine, which is not ideal for those sensitive to it. Masala Chai in India: This spiced tea blend combines black tea with cinnamon, cardamom, ginger and cloves, all known for their digestive and anti-inflammatory benefits. However, it often comes with milk and sugar, which can outweigh its health perks if overdone. Black Tea in the UK: A staple in British culture, black tea contains antioxidants like theaflavins and thearubigins, which support heart health. But again, the caffeine content and frequent addition of sugar or milk can counteract its benefits. Matcha: This finely ground green tea is a powerhouse of antioxidants and L-theanine, which supports calm alertness. But it's potent and pricey and definitely not caffeine-free. This finely ground green tea serves as a potent source of antioxidants Image: Diana/pexels What makes rooibos stand out? It's naturally caffeine-free, low in tannins, gentle on the stomach, and packs a serious antioxidant punch all without needing any additives. Why rooibos is a wellness essential Experts across the country agree: rooibos is not just a trendy health tea; it's a functional drink with science-backed benefits. Professor Jeanine Marnewick of CPUT has shown that rooibos helps combat oxidative stress, a contributor to chronic illness. Professor Amanda Swart of Stellenbosch University identified aspalathin, a unique Rooibos compound, as a natural aid for blood sugar and adrenal health. Professor Christo Muller from the SAMRC highlighted rooibos' potential to support glucose metabolism and reduce inflammation, key factors in preventing or managing type 2 diabetes. 'These findings make Rooibos one of the few herbal drinks with evidence-based functional health claims,' says Terblanche. 'It's accessible, safe and locally grown, a true South African gem.' In a wellness world filled with green powders, collagen shots, and pills with hard-to-pronounce names, rooibos offers something refreshingly simple: a self-care moment that nourishes body and mind.
