This special set comes with a Red Spot Cream and an Anti-Blemish Toner.
I tried applying the two products both seperately and together in order to see the effectiveness of the two products individually. For the Red Spot Cream, I think it is very effective to be applied alone, with a thick and generous layer after washing your face in the evening. Most of the time, your acnes would
disappear after one or two evenings' application, depending on how 'stubborn' your acnes are! Well, I said "most of the time" because sometimes it didnt work as effective (but about 80% of the applications work! And I think that's reasonablly good already!) As it has rightly said in the product description, you may feel a bit of residue (especially if you put make-up on the top, it can cause caking!) due to the texture of the Red Spot Cream. Thus, I usually apply Anti-Blemish SPOT-X at day time under my make-up, and the Red Spot Cream in the evening. (You may refer to my review about the SPOT-X treament.) I highly recommend the usage of this pair of products!
As for the Anti-Blemish Toner, I am not very sure about the effectiveness. I have tried applying it under the anti-blemish SPOT-X at day time, and under the Red Spot cream in the evening. But I have not seen any noticeable change "with" and "without" using it.
