5 skin health myths to stop believing now | Body Stuff with Dr. Jen Gunter
Understanding Our Skin
In this section, Dr. Jen Gunter discusses common myths about our skin and provides insights into its complexity and functions.
Myth #1: Healthy Skin is Flawless
- Healthy skin is not just about having a clear, blemish-free surface.
- The skin is a living organ with complex functions beyond its appearance.
- The outer layer of the skin, called the epidermis, consists of different cell types that serve various purposes.
- Keratinocytes are replaced every four weeks and form a protective layer on the surface.
- Melanocytes produce melanin, which gives color to our skin.
- Langerhans cells act as security guards against pathogens.
Myth #2: Sunscreen is Only Needed on Sunny Days
- Ultraviolet (UV) rays from the sun can damage our skin's DNA.
- UVA rays penetrate the dermis and accelerate aging by damaging collagen.
- UVB rays cause sunburn by cooking the epidermis.
- Wearing sunscreen with SPF 30, even on cloudy days, protects against sunburn, premature aging, and skin cancer.
Myth #3: Darker Skin Doesn't Need Sunscreen
- People with darker skin produce melanin that offers some natural protection from the sun but not enough to prevent damage.
- Black and Hispanic patients are more likely to have advanced stages of skin cancer due to systemic racism in medicine.
Myth #4: Pores Can Be Shrunk
- Pore size is largely determined by genetics and does not shrink permanently.
- Irritation from makeup or harsh products can temporarily expand pores.
Myth #5: Chocolate Causes Acne
- Acne occurs when hair follicles get clogged with oil and dead skin, allowing bacteria to overgrow.
- Studies linking chocolate consumption to acne are inconclusive, with conflicting results influenced by funding sources.
- A healthy diet overall is beneficial for both the body and skin.
