Mary Quant Go Deeper clay pack is perfect for weekends. Simply spread it on your face and rinse it off when it dries. It doesn't make your face feel tight, but it leaves your skin feeling smooth. I love it, and have been buying it for over 10 years. (This is one of the products that a former Mary Quant fan still uses today.) The scent is the best thing about it, it's perfect for relaxing on the weekend.
I used it when I was younger and it made my pores less noticeable and cleared up acne scars. I wanted to use it again, so I bought it and used it once or twice a week, so I think it's good value for money. I was impressed by how shiny my skin became after using it, so I'd like to buy it again.
I use it about three times a week after my nighttime cleansing routine, which doesn't require double cleansing, and even during pollen season, I no longer have to worry about blackheads around my nose! This is the perfect product for me, as I'm lazy and can't keep up with too many steps. I've finished one bottle and am on my second!
It's a soft clay paste that's easy to apply to the skin. I love the dry clay paste type and have used a variety of them, but I found this one to dry very slowly. I can't use it when I'm in a hurry. I think it's because of the soft texture... But once it dries and I wash it off, it leaves a refreshing feeling without making my skin feel tight, which I like. I also think it's good value for money.
I consulted with Mary Quant about my concerns about pores and they recommended this product! After using it, I noticed that my pores were noticeably less noticeable, so I decided to buy the full product. Immediately after applying it to my skin after taking it out of the container, I felt a slight alcohol-like cooling sensation. I have sensitive skin, but even after leaving it on for about five minutes, it didn't sting, which was great. Another great point was that it was easy to wash off! I use it about twice a week and I can see that the blackheads in my pores are decreasing, so I plan to continue using it!
