No results on neck

Hello. I have a neck that is a little black on the sides and on the back. I've been using Diana Stalder's SURELY WHITE Body Whitening Lotion for about a month, and my neck still looks the same. It's as if I never even used it! I use it twice every day - Once in the morning, and once at night. I admit I don`t always use sunscreen on my neck like I should, but everytime I go out in public and it's daytime, I wear collared shirts, but I doubt the sun shines on my neck while I have the lotion on. I also have to say that I don't apply moisturizer on my neck. Could that be a reason why I'm not seeing results?

I hope you can tell me why I'm not seeing any results.

Answer:

Hello, sunlight can penetrate through clothing. The effective SPF of clothing is only SPF5, while the suggested sunscreen is at least SPF45 or higher. Please remember that skin lightening without sunscreen is futile, just as emphasized on the instruction sheet.

Keep me updated after you've used sunscreen for the next month. :)
