I am a DRPW, and I am using Dr. B's recommendations for all of my skin care. I started using the Neutrogena Dry Touch Helioplex 55 a few weeks ago as I want a higher SPF since I walk outdoors for 45 mins. most days plus the usual sun exposure with driving, etc. in sunny California. Some days it really stings certain areas of my face and neck (like today!) but other days I feel nothing. The stinging generally goes away but sometimes I have intermittent slight sensations of stinging or itchy stinging. Any suggestions? I have changed nothing else in my regime, and I hate to give up this sunscreen.
