How to Slow Skin Aging This Summer: The Key Factor You Can Control

Intrinsic vs. Extrinsic Ageing 

Intrinsic ageing is the natural process driven by genetics and time. It involves gradual thinning of the skin, loss of collagen and elastin, and reduced hydration, leading to fine lines and dryness. 

Extrinsic ageing is mainly caused by environmental factors, especially chronic UV exposure (photoaging). It appears as deeper wrinkles, rough texture, and uneven pigmentation. This may develop earlier than intrinsic ageing. 

Who’s Most at Risk? 

In general, wrinkles appear 10-20 years earlier in fair skin than in Asian skin, while dark-skinned individuals from African and Asian ethnic groups are more prone to hyperpigmentation and sun spots. 

How to Slow the Process 

While intrinsic ageing is inevitable, photoaging is preventable. Research has shown by applying a broad-spectrum sunscreen (SPF >30), subjects found improvement in all photoaging parameters as early as week 12, with all subjects showing improvement in skin clarity and texture.   

Your Summer Takeaway 

If sunscreen isn’t already part of your daily routine, now is the time to start. Daily use of a facial broad-spectrum photostable sunscreen may visibly reverse the signs of existing photodamage, in addition to preventing additional sun damage.
