Skin is the largest organ in your body.
It has 3 layers the epidermis, dermis and hypodermis here is a brief overview:
Epidermis
The epidermis comprises multiple layers and cells, primarily functioning to safeguard the skin by preventing bacteria, parasites, fungi and germs from infiltrating the bloodstream. Additionally, it provides protection against environmental elements, such as precipitation and sunlight.
The epidermis also contributes to skin hydration and influences skin colour through the production of melanin.
Fun fact the epidermis constantly makes new skin cells – Stratum basal.
What conditions and disorders impact the health of the epidermis?
- Acne
- Rosacea
- Dandruff
- Eczema
- Infection
Dermis
The dermis, which serves as the intermediate layer situated directly beneath the epidermis, consists of two primary layers: the reticular dermis and the papillary dermis. The reticular dermis constitutes the lower layer and is characterised by a substantial presence of blood vessels, hair follicles, lymphatics, nerves, and fat cells. In contrast, the papillary dermis is the upper layer of the dermis. It is thinner than the reticular dermis and contains collagen fibres, immune cells that combat bacterial infections, as well as blood vessels and nerve fibres. Collectively, these structures function synergistically akin to a nut and bolt.
The dermis supports the epidermis by providing strength, while blood vessels facilitate the delivery of nutrients to the epidermis. The dermis also plays a role in regulating sweat and in sensing hot and cold. Additionally, the sebaceous glands within the dermis secrete oil (sebum), which helps keep the skin and hair hydrated and also adds shine.
Conditions and disorders that affect the dermis:
Hypodermis
The hypodermis is the bottom and deepest layer of skin in your body. It serves many vital functions, including storing energy, connecting the dermis layer of your skin to your muscles and bones, insulating your body, and protecting it from injury. As you age, the hypodermis diminishes in size, causing your skin to sag.
The hypodermis provides insulation through a layer of fat, which helps to retain body heat and maintain temperature. Additionally, it serves as a shock absorber, protecting bones and muscles. The hypodermis is home to larger blood vessels and nerves that nourish the dermis, providing nutrients and sensory input to the skin.
Your skin cells regenerate approximately every 28 to 42 days, though this process slows down with age.
The skin is wonderfully complex, and what we’ve shared here is just a glimpse into the fascinating functions it carries out. The key takeaway is that we should genuinely support our body and skin by being mindful of what we put into it, how our environment affects it, and how we care for any injuries it might sustain.
A few ways to care for your skin include:
- Drink at least eight glasses of water each day
- Try using a gentle, fragrance-free soap for your skin.
- When bathing, opt for lukewarm water, as hot water can dry your skin.
- After washing, gently pat your skin dry with a soft towel instead of rubbing it.
- Don’t forget to apply sunscreen with at least 30 SPF to keep your skin protected!
- Regular exfoliation can help maintain healthy and resilient skin by promoting cell turnover and removing dead skin cells.
- Properly treat your wounds to prevent infections.
