WHAT IS SUNSCREEN? WHY IT IS NEEDED
Sunscreen is a derma product apply to protect against the harmful effects of the ultraviolet (UV) rays of the Sun.
The two types of UV rays that can damage the skin are:
- UVA Rays
- UVB rays.
Overexposure to UV rays can cause sunburn, premature aging, skin discoloration, and increased skin cancer risk.
Sunscreen protect the skin from these harmful effects by absorbing or reflecting the UV rays before they penetrate it.
It also helps prevent sunburn, reduce the risk of skin cancer, and prevent premature aging.
- Use sunscreen daily, even on cloudy days, as the Sun’s UV rays can still penetrate the clouds.
- We recommend to use a broad-spectrum sunscreen. Such as SPF 30, it protects from both UVA and UVB rays, i.e. (SPF 30)
Application of Sunscreen must be to all exposed areas of the skin, including the face, neck, ears, and hands, and should reapply every two hours or after swimming or sweating.
WHAT IS SPF?
- The SPF (Sun Protection Factor) in a sunscreen indicates the amount of UVB radiation blocked by the product.
- The higher the SPF, the greater the protection against UVB rays. The recommended minimum SPF by dermatologists is SPF 30.
- UV Index, which measures the intensity of UV radiation at a given time and place.
- The higher the UV Index, the higher the risk of skin damage
- The American Academy of Dermatology (AAD) generally recommends a broad-spectrum sunscreen with SPF30 or higher daily, regardless of the temperature or weather conditions.
When the UV Index is moderate to high, applying sunscreen more frequently and taking additional precautions, such as seeking cool place or shade and wearing protective clothing, is essential.
- A higher SPF sunscreen provide adequate protection in scorching temperatures or when participating in outdoor activities for an extended period.
It is always important to follow the label instructions of the sunscreen product and reapply it as directed, especially after swimming or sweating.
IF NO SUNSCREEN IS USED, WHAT MAY BE THE ISSUE ON THE SKIN?
If sunscreen is not used, the skin exposes to harmful UV rays from the sun, causing several skin problems. These include:
SUNBURN: Sunburn is a common problem due overexposure to UV rays. It can cause redness, pain, and peeling of the skin.
PREMATURE AGING: Exposure to UV rays causes premature aging of the skin, which leads to wrinkles, fine lines, and age spots.
SKIN DISCOLORATION: Prolonged exposure to the sun without protection can also lead to hyperpigmentation, which is the darkening of the skin in certain areas.
SKIN CANCER: Unprotected sun exposure is the development of skin cancer. UV radiation damages the DNA in skin cells, which can lead to the development of cancerous growths.
Conclusion: Using sunscreen before venturing into to sun helps protect skin from the harmful effects. So, it is a good idea to apply SPF30 before venturing out in the sun’s rays. It should apply as directed by its cover.
