Benefits include:

• Improved skin texture and tone
• Softening of fine lines and wrinkles
• Reduction in acne scarring
• Refined pores

Collagen loss is a natural part of the ageing process, but the right skincare and treatments can help support stronger, healthier-looking skin.

At Define by Jill, we take a corneotherapeutic approach, combining customised Dermaviduals skincare with advanced, evidence-based treatments tailored to your skin’s unique needs.

Our favourite Dermaviduals collagen-supporting products include:
• Vitamin A Nanoparticles to encourage skin renewal and support collagen production
• Vitamin C Liposome Concentrate to assist collagen synthesis and provide antioxidant protection
• Hyaluronan-NAG Liposomes to deeply hydrate and support skin density
• DMS Base Cream High Classic Plus to strengthen and protect the skin barrier

To further support skin firmness, texture and overall skin health, we also offer a range of treatments designed to complement your home care and target the visible signs of collagen loss.

Every treatment recommendation at Define by Jill is personalised, results-focused and delivered ensuring safe, ethical and professional care at every step.
