Skin Ageing

The skincare industry has sold consumers a topical story for decades. Real skin ageing happens at the cellular level — collagen, elastin, mitochondrial function, glycation, inflammation — and none of those respond meaningfully to yet another moisturiser. Understanding the actual biology of skin ageing is how you spend less money on products and get better outcomes.

6 takeaways from this chapter.

• The cellular hallmarks of skin ageing — senescence, glycation, mitochondrial decline, collagen loss
• The small number of topical ingredients with genuinely strong evidence (retinoids, vitamin C, niacinamide, SPF) versus the huge number that don't
• Why nutrition, sleep, and stress age skin faster than anything you put on it
• The role of sun exposure — the single biggest controllable driver of skin ageing
• Emerging treatments — microneedling, peptides, light therapy — with evidence ranked honestly
• Where copper peptides and cellular support genuinely move the needle
