Grade of Recommendations
|
| SPF (Sun Protection Factor)
|
- An ideal sunscreen should have the following properties:
- Broad-spectrum
- Both UVA & UVB filters
- Atleast SPF 30
|
|
| Water resistance
|
- Sunscreen providing water-resistance for 40-80 minutes must be worn in following conditions:
- Water immersion
- Excessive sweating
- Contact with sand
- Physical contact causing increased skin friction
|
| Organic vs inorganic sunscreens
|
- Whether the components of sunscreen are organic or inorganic, recommended sunscreen must be broad spectrum with both UVA & UVB filters
|
| Lip protection
|
- Whole lip should be generously covered by high-SPF (>/= 30) and reapplication of lip sunscreen
|
| Sunscreen application
|
- Sunscreen is recommended to be applied according to following guidelines:
- Should be applied liberally (approximately 45 ml) to all the exposed areas
- Strong reapplication within a period of 8 hours is mandatory only after activities that may remove the sunscreen layer such as sweating, swimming, or friction
- Should be applied before any sun exposure and at least 20 minutes before the water activities
|
|
| Patient education on sunscreen
|
- Patients should be educated about the meaning of SPF and its effectivesness
|
| Sunscreen safety
|
- Sunscreens have a favorable risk-benefit profile, hence, are considered to be safe overall
- There is still a risk of following few complications due to sunscreen application in some people:
- Photoallergy (most common, but quite rare)
- Reproductive toxicity
|
| Sunscreen benefits
|
- Prevents photoaging
- Prevents melanoma and non–melanoma skin cancer
|
| Sunscreen vehicle
|
- Highest SPF and water resistance properties of sunscreen can be obtained by using a water-in-oil emulsion formulation for sunscreens
|
|
| Expiry date
|
- Avoid using sunscreens past the manufacturer-specified expiry date/recommended period after opening
- Sunscreens should be stored at normal room temperature in order to ensure their proper stability
