Reply you can. If you use an equal amount, and moisturizer, and tone, the SPF record is 22, 5. This is assuming that your two funds are no components that should not be used together. That is the level of SPF will be lower than 30.

However, you can give a chance moisturizer SPF 30, so he retained his high. You do not need to mix products. That is, you need to wait for a moisturizer with an SPF of 30 will be absorbed into the skin and then apply foundation with a lower SPF.
