CARE AND USE

pH sensors have a limited life and response time gets longer with age. Properly maintaining your pH Tester will give you fast, accurate results for longer.

You can extend the life of your pH electrode in the following ways:

  1. Always store with the cap full of buffer or storage solution MA9015 not water.
  2. Clean your tester regularly by soaking in cleaning solution MA9016
  3. Calibrate after cleaning and/or storage before testing to adjust for changes in the pH sensor.
  4. Gently stir the tester in the sample for a faster result.

The best pore reducer, even on older complexions!
Size: 2.03 Fl Oz (Pack of 1)
Nothing has ever worked reducing my enlarged cheek and nose pores over the years. Now I've finally found something that works. By the second day there was noticeable results and by the end of the first week even the small wrinkles under my eyes was gone! I use it with my normal skin care routine but I won't do without this again.

Good and Hydrated
Size: 1.01 Fl Oz (Pack of 1)
It’s very good and hydrates very well. Not a fast or much improvement on pores. But very good to hydrate your skin.

Just buy it
Size: 3.38 Fl Oz (Pack of 1)
I am not even sure I want to do this review because this might mean this product gets sold out. But I wont gate-keep. Get it. This has changed the game with my skin care. I use it twice a day and let me tell you, the compliments I get are incredible. It is not greasy at all, absorps quickly, super light weight and does not irritate my skin. My skin is glass smooth. I have bought this for everyone in my life. Male and Female. I use it, let it dry then add moisturizer or sunscreen.

Works well with others!
Size: 2.03 Fl Oz (Pack of 1)
Initially and by itself, I really didn’t see any changes to my face that made me confident with this product. But now that I have a skin routine, I think it works well! Now I like it and I see changes. But alone or with few products, I’m not sure how effective it is!

I’ve never used such a great pore minimizer for this reasonable of a price. I love how smooth and clean it makes my face feel. I’ve been using it twice a day after cleansing my skin. Noticeable difference in visible pores and decrease in black heads on my nose and chin. Highly recommend!! Come on with this price, you have nothing to lose.
