Question
If I add 5% Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S) to my moisturizing cream, will it provide sufficient sun protection to replace a dedicated sunscreen?
Answer
Based on the information provided, adding 5% Tinosorb S (Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine) to a moisturizing cream is unlikely to provide sufficient sun protection on its own to replace a dedicated sunscreen.
- The calculation mentioned suggests that 5% Tinosorb S might only result in an SPF of around 12 (or as low as 6 with typical application amounts).
- For adequate daily sun protection, higher SPF values (like SPF 30 or 50) and good UVA protection (indicated by PA rating) are generally recommended.
- Combining multiple sunscreen agents is often advised for better efficacy and broader spectrum protection.
Therefore, while it adds some protection, relying solely on 5% Tinosorb S in a moisturizer would likely not be enough for comprehensive sun protection, and using a separate sunscreen is still advisable.
