HOW TO KEEP YOUR SKIN FIRM AS YOU AGE

We’ve all heard about collagen, but what role does it actually play in keeping our skin youthful? As one of the most vital proteins in the body, it is the foundation of smooth, plump and firm skin. Unfortunately, as we age, production slows down, leading to fine lines, sagging and loss of elasticity. The good news? At Persona, we offer treatments that not only restore, but also stimulate your body to make more of it naturally!

What is Collagen?

Collagen is a structural protein found in the skin, muscles and connective tissues. Think of it as the scaffolding that holds everything in place. In your skin, collagen works alongside elastin and hyaluronic acid to keep it supple and firm. 

By the age of 30, collagen production decreases by around 1% each year. Add in factors like sun exposure, stress and poor lifestyle habits, and the process speeds up even faster. 

Signs of potetntial loss: 
  • Fine lines around the eyes and mouth 
  • Thinning or crepey skin 
  • Loss of jawline definition 
  • Sagging cheeks or under-eye hollows
How to stimulate Collagen production:

The beauty of modern aesthetics is that we can now actively encourage the skin to produce more. At Persona, we recommend: 

Lifestyle support for Collagen:

It’s not just about treatments. Simple lifestyle changes can add protection too: 

  • Wear daily SPF – Persona recommends Heliocare 360 
  • Eat a balanced diet. Rich in vitamin C, protein and antioxidants
  • Avoid smoking and limit alcohol
FAQs:
  • How long do these treatments last? 

Results vary, but with proper maintenance, improvements can last 12-18 months

  • Are these treatments painful? 

Most procedures are quick and involve minimal discomfort

Collagen is the backbone of youthful skin, and while natural ageing is inevitable, you don’t have to accept dull or sagging skin. With the right treatments and care, you can boost your collagen levels and enjoy firmer, fresher looking skin!
