#CoffeewithDentists: Oral Health Tips with Dr. John Porter


In a recent episode of the online series #TeawithMDs, Dr. Mary Stevenson discussed the importance of sunscreen. Sunscreen is an essential skincare product that protects the skin from the harmful effects of the sun. Dr. Stevenson emphasized that sunscreen should be a regular part of everyone's skincare routine.

According to Dr. Stevenson, sunscreen not only prevents sunburns but also reduces the risk of skin cancer. She explained that the harmful ultraviolet (UV) rays from the sun can damage the skin and increase the chances of developing skin cancer. Sunscreen creates a protective barrier on the skin, limiting the penetration of these harmful rays.


Dr. Stevenson also addressed common misconceptions about sunscreen. She clarified that SPF (Sun Protection Factor) is not directly related to the amount of time one can spend in the sun. Instead, it indicates the level of protection against sunburns. Higher SPF sunscreens provide better protection.

Additionally, Dr. Stevenson recommended using broad-spectrum sunscreen, which protects against both UVA and UVB rays. UVA rays can prematurely age the skin, while UVB rays cause sunburns. By using broad-spectrum sunscreen, individuals can safeguard their skin from both types of damaging rays.

Lastly, Dr. Stevenson highlighted the importance of reapplying sunscreen throughout the day. She advised using a sufficient amount and reapplying every two hours, especially when in direct sunlight or after swimming or sweating.

Overall, Dr. Stevenson emphasized the significance of sunscreen in protecting the skin from the damaging effects of the sun, reducing the risk of skin cancer, and maintaining a healthy complexion.
