We asked Dr Josh to also clear up the most common questions about ageing skin — and what you can really do about it.
1. At what age do you start to visibly look older?
Many people think wrinkles are the first sign of ageing, but that’s actually a myth. In most cases, the earliest visible change is a loss of skin radiance and uneven tone in the late 20s to early 30s. This happens as collagen production begins to decline and cell turnover slows down. Fine lines usually follow, but dullness and pigmentation are often the first giveaways.
2. What ages skin the most?
Sun exposure is the single biggest contributor to visible skin ageing. UV rays penetrate the skin and damage collagen and elastin fibres, leading to wrinkles, sagging, and pigmentation. While genetics and lifestyle play a role, protecting your skin from UV is by far the most effective way to slow ageing
3. Can I reverse my skin ageing?
A common misconception is that drinking collagen supplements or applying collagen creams will “reverse” skin ageing. In reality, most collagen molecules are too large to penetrate the skin, and oral supplements may only have modest benefits. What truly works are treatments that stimulate your own collagen production, like retinoids, chemical peels, or energy-based devices. Combined with sunscreen and antioxidants, these can improve the look of ageing skin.
4. What habits slow down ageing?
Daily sunscreen use is the most powerful habit you can adopt. A diet rich in antioxidants, regular exercise, quality sleep, and stress management also supports healthier skin. Adding evidence-based skincare ingredients like retinoids and vitamin C can further protect and repair skin as you age.
5. What routine is best for ageing skin?
An effective routine doesn’t need to be complicated. In the morning, use a gentle cleanser, an antioxidant serum such as vitamin C, and broad-spectrum SPF 30 or higher. At night, focus on repair with a retinoid and a nourishing moisturiser. Consistency is key — these steps build resilience and maintain healthier, younger-looking skin over time.
