What our customers are saying
I have oily skin that gets shiny within an hour of washing my face, but when I use this in the morning, I feel like the shine is kept to a minimum in the morning (it gets shiny in the afternoon...). It has a watery texture and is very refreshing. It contains a strong amount of ethanol, so if you have rough skin, it may sting or cause redness, so those with sensitive skin should be careful. It only moisturizes slightly, so I think it's best for people who want a refreshing feel.
I have combination skin that gets quite shiny during my lunch break, so I always have to touch up my makeup. I use separate skincare for the T-zone and other areas, so these are my impressions after using it only on the T-zone. It doesn't completely eliminate the shine, and although it still bothers me around lunchtime, I do feel like it's gotten less oily. I'd like to try other products that suppress sebum secretion, so I'm not sure if I'll repurchase, but I liked it so much that I don't think I'll ever go back to lotions that don't claim to suppress sebum secretion.
I haven't felt any definitive effects yet, but I'm looking forward to seeing the effects of Rice Power No. 6.
I use it on my nose and forehead, where I have a lot of oil. I feel like the oil is less than when I don't use it. It was fine on my nose, but it made my forehead a little itchy, so it might not be suitable for winter, when oil production is lower. I think my impressions will change if I try it in the summer, so I'll write another review then.
I started to worry about my pores, so I did some research and found this product to be good, so I gave it a try. I definitely feel like my pores are no longer a concern, and it really does seem to penetrate! I've been using alcohol-free products up until now, but even though this one contains alcohol, I can use it without feeling any irritation!
