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.

Superb screen protector
Model: iPad 11th A16 2025/10th
Order this product with next day delivery for my new iPhone and I’ve had it on there for about a week. It was super easy to put the screen on the phone. It comes with like a guy that looks almost like a cover so excellent no air bubbles underneath knock on wood. I have not dropped my phone yet so I can’t speak to. It’s protectiveness but it seems like it’s gonna do a great job. I would definitely purchase again reasonable price good quality.

Good protector but bubbles at install
Model: iPad 11th A16 2025/10th
This is probably the 10th or so glass screen protector I have bought and installed for reference. Compared to others I’ve used in the past, it was just as easy to install but I struggled with bubbles under the screen and I took weeks for them to come out. Works as it should, good visibility and protection, just went it was easier and quicker to install.
