Thank you very much for your question. Let me just say that it takes very active ingredients to really bleach someone’s skin. It is highly unlikely that an over-the-counter preparation is going to do this. So I would not worry about this being an issue (as long as your sunblock is not causing you any sensitivity). Please continue to use a good sunblock every single day as this is absolutely vital. Please feel free to contact me again for any other questions you may have.
