Contrary to popular belief, SPF 50 doesn't provide double the protection of SPF 30. The difference in UVB protection is only marginal.
Some SPF 50 formulations use time-release technology, offering extended protection against harmful UV rays, even during prolonged sun exposure.

Water-resistant sunscreens lose effectiveness after swimming or sweating, emphasizing the need for reapplication, regardless of SPF level.
Applying a thick, even layer of SPF 30 can be more effective than a thin layer of SPF 50. Consistency in application is key.
Individuals with fair skin may benefit more from SPF 50, while those with darker skin tones may find SPF 30 sufficient. It's about matching the SPF to your skin's needs.
SPF primarily measures protection against UVB rays. Look for "broad-spectrum" to ensure defense against both UVB and UVA rays.
Sweating can dilute sunscreen effectiveness. Opt for water-resistant formulas and reapply after heavy sweating.
While sunscreen blocks some vitamin D synthesis, it's not a major factor. Most people get sufficient vitamin D from incidental sun exposure.
Relying solely on SPF in makeup might not provide adequate protection. Use dedicated sunscreen for comprehensive coverage.
