“Collagen is what keeps skin firm, plump and resilient, but the body naturally produces less of it as we get older. The problem is that everyday habits – things many people do without thinking – can speed up that breakdown. Over time, that loss of collagen shows up as thinner skin, deeper lines and a loss of elasticity.”
1. The “healthy” sugar trap
How it wrecks collagen: It’s not just biscuits or fizzy drinks. Everyday sugar in flavoured yoghurts, breakfast bars, and coffee shop drinks can quietly accelerate collagen breakdown. Frequent blood sugar spikes fuel glycation, where sugar molecules bind to collagen and form advanced glycation end products (AGEs). These stiffen the fibres, making skin less flexible and reducing its natural bounce over time.
What to do instead: Focus on stabilising blood sugar rather than cutting sugar completely. Pair carbs with protein, choose high-fibre meals, and keep sweet treats occasional. A breakfast of eggs, nuts, or Greek yoghurt sets the tone for the day and reduces harmful spikes.
2. Scrolling at midnight
How it wrecks collagen: Late-night phone light and stimulation can delay melatonin release and shorten restorative sleep, which your skin uses for repair and collagen maintenance.. Delayed or fragmented sleep reduces the time skin has to complete its nightly recovery cycle, leaving collagen maintenance compromised.
What to do instead: Protect the hour before sleep. Dim lights, switch devices to night mode, and avoid emotionally stimulating content that raises cortisol. Keeping a consistent sleep window matters more than perfection and helps your skin’s repair rhythm stay steady.
3. Taking hot showers
How it wrecks collagen: Very hot water strips the skin’s protective lipids. Repeatedly compromising the skin barrier causes chronic dryness and inflammation, which accelerates collagen degradation over time.
What to do instead: Opt for shorter, lukewarm showers and use gentle cleansers. Moisturise within minutes of stepping out to support your skin barrier and reduce inflammation over time.
4. Vaping
How it wrecks collagen: Nicotine narrows blood vessels, reducing oxygen and nutrient delivery to the skin. Over time, this impairs collagen maintenance and slows repair after everyday stressors such as UV exposure.
What to do instead: Cutting down on vaping can help improve circulation. Create vape-free windows, delay your first vape of the day, or build friction into your routine to reduce automatic use. These small adjustments protect collagen without relying solely on willpower.
5. Overdoing acids and scrubs in the name of “glow”
How it wrecks collagen: Repeated over-exfoliation triggers low-grade inflammation, signalling the skin to break down more structural proteins. Collagen thrives in a calm environment, and constant resurfacing undermines long-term skin strength.
What to do instead: Alternate active exfoliation days with barrier-support days. Focus on hydration, ceramides, and daily SPF. Protecting against UV damage remains one of the most effective ways to preserve collagen over time.
