Can Tianqidan essence be mixed with Clinique whitening essence?

Tianqidan essence can be mixed with Clinique whitening essence.

But the effect will be better if used separately. Because the essence itself is a highly intensive nutritional skin care product, it may cause a burden on the skin when used together, so it is best to use it separately in the morning and evening maintenance. Essence is generally in emulsion state, which is relatively easy to be absorbed by the skin and is not easy to burden the skin. The use of two essences together will not be too heavy, but the use of essences with different efficacy may affect their respective efficacy, so the effect of using essences with different efficacy alternately will be better.
