How To Use

Step 1

After cleansing in the evening, apply 2 pumps of Crystal Retinal to the face and neck. Allow to absorb then follow with a moisturiser. We recommend Advanced Night Restore which is specifically designed to be used after vitamin A.

Step 2

For new users of Crystal Retinal, phase application in gradually. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night. You should always use a sunscreen the next morning after using vitamin A.

We recommend using at least 1 tube of your current Crystal Retinal strength before moving up the ladder to the next strength.

Great gift!
Color: Light Blue
I bought these for teacher appreciation gifts and the recipients loved them! The light blue ones just add a pop of color and I’ve been told they keep their coffee warm ALL day. What a sweet treat for deserving educators. I plan on buying one for my desk!

Does the job, wish it had some safety features
Color: Black
Good value for the price, and it definitely keeps your coffee warm. I do wish it had a safety feature where it could turn off on its own, or a less sensitive on/off button. It goes on easily and gets very hot, so it can be dangerous with little kids.

FINALLY able to enjoy my morning coffee without reheating!!!!
Color: Black
Since this mug warmer arrived, I have finally been able to enjoy a relaxing cup of morning coffee. Value and quality are on point. This warmer keeps my coffee warm to the last drop. The cord is long enough to reach an outlet near the end table, easy and simple operation (tap on, tap to lower temp up to two times then final tap off). Auto shut off after 4 hours which I have not used yet as I always unplug my unit after each use, however it is nice to know that is an option. Just one suggestion, Using a mug lid with unit also helps keep the hot beverage at a consistant temp. I LOVE IT and wish I ordered one sooner.

Perfect
Color: Light Blue
For me this coffee warmer is perfect. The disk sides are just right. High enough for a good fit, but not so high you risk sloshing your beverage. The color (blue) is exactly as displayed. Works great and a very good price.

Works only moderately well to keep coffee hot
Color: Light Blue
Not quite what I expected. Although the base heats up as described, it does not keep my coffee as warm as I would expect at the highest temperature.
