The dermis, the middle layer of skin, is crucial in maintaining skin health and appearance. Comprising approximately 90% of skin thickness, the dermis supports the epidermis, regulates body temperature, and facilitates sensation. However, the dermis undergoes significant changes with age and inflammation, leading to wrinkles, sagging, and skin dullness.
Structure and Function of the Dermis
The dermis consists of:
1. Collagen fibers (70-80%): Providing strength, elasticity, and firmness.
2. Elastin fibers (5-10%): Allowing the skin to snap back into place.
3. Fibroblasts: Producing collagen, elastin, and glycosaminoglycans (GAGs).
4. Blood vessels: Regulating temperature, nutrient delivery, and waste removal.
5. Nerve endings: Facilitating sensation and pain perception.
Ageing in the Dermis
As we age, the dermis undergoes:
1. Collagen degradation: Enzymes break down collagen, leading to wrinkles and sagging.
2. Elastin loss: Reduced elastin production impairs skin elasticity.
3. Fibroblast decline: Decreased fibroblast activity slows collagen and elastin production.
4. Glycosaminoglycan (GAG) depletion: Reduced hydration, skin plumpness.
5. Vascular changes: Decreased blood flow, and nutrient delivery.
Inflammation in the Dermis
Chronic inflammation in the dermis contributes to:
1. Collagen breakdown: Inflammatory enzymes degrade collagen.
2. Elastin degradation: Inflammation reduces elastin production.
3. Fibroblast dysfunction: Inflammation disrupts fibroblast activity.
4. Skin barrier disruption: Inflammation compromises the skin's natural barrier.
5. Oxidative stress: Free radicals damage dermal cells and collagen.
Consequences of Dermis Aging and Inflammation
The combined effects of ageing and inflammation in the dermis lead to:
1. Wrinkles and fine lines
2. Sagging skin
3. Dullness and loss of radiance
4. Dryness and dehydration
5. Skin discoloration and hyperpigmentation
Reversing Dermis Aging and Inflammation

The dermis plays a vital role in maintaining skin health and appearance. Understanding the changes that occur in the dermis with ageing and inflammation enables us to develop effective strategies for prevention and treatment.
By combining topical skincare, lifestyle changes, and professional interventions, you can promote a healthier, more radiant dermis and combat the signs of ageing. Always consult a registered dietician for a personalized diet plan.
