Are titanium dioxide and hydroquinone harmful ingredients when added together?

Rx of Sunspots: Hydroquinone is used to treat spots caused by the sun. Once you have treated the spots, you need to protect from further sun damage. Titanium dioxide is an excellent sunblock to protect from both UVB and UVA. It is more practical than most other sunblocks as you only have to replace it if you rub or wash it off, not hourly. Zinc oxide is even better. Look for 8% zinc oxide, not SPF. ...Read more

With hydroquinone, do you put it on the entire face or do you just dot it on each dark mark?

With hydroquinone, do you put it on the entire face or do you just dot it on each dark mark?

Be selective: Hydroquinone stops melanin production when used on skin. If your dark spots are recent from sun exposure you should only use the cream on the spots. If used on the entire skin, your skin tone will lighten and could make spots appear more. First you need a diagnosis to determine what your spots are from. HQ is usually a prescription product so consult with your doctor. ...Read more
