If your going to try it on your face then you have to be really careful as it is strong and some people have had bad experiences with putting it on their face. With me it took a couple of weeks until I noticed I was getting lighter. I just used the cream, but the lotion should work too, no need for the oil on your face though. Within about a week or 2 my face became really sensitive and it burned when I was rubbing it in, I was also using the diana stalder papaya kojic acid soap which is also strong because it worked like an exfoliator which made my skin more sensitive. I would think that putting the oil on the face would cause acne though, then again ltheres alot of mineral oil is in bio claire.
You can try using your cream and oil mixture if you like, just be cautious because it is quite strong. I used it twice a day, but you can start off using it once a day like at night and work your way up from there to twice a day within a week or 2. During the lightening process, my skin did start to lighten unevenly and then it evened out within a week or 2. Personally I don't believe bio claire is the best on the market dealing with safety reasons, but it's what I use for now because it's cheap and it works...at least until I find something that works just as good, safer, and affordable.
But, remember to use an exfoliator for the face and good sun block. I exfoliate 2-3 times a week and carry my sunblock with me in my purse. Also, if your skin starts to feel tender, try using a good moisturizer after applying the bio claire.
