Retinal vs. Retinol:
The Vitamin A Showdown
When it comes to age-defying skincare, vitamin A is the absolute gold standard in keeping your skin looking younger for longer. Nothing comes close in terms of the clinical evidence for its results and the amount of benefits it provides for the skin. Two of the most well known forms are retinol, the tried and tested form and most popular in skincare; and retinaldehyde, the next-generation vitamin A.
Retinal is a rare form of vitamin A that is even more powerful than retinol. The key difference is that retinaldehyde is much closer in power to retinoic acid, but without the infamous side effects. It therefore acts up to 11x faster than retinol at providing anti-ageing, radiance-boosting and decongesting benefits to the skin.

LOVE CRYSTAL RETINAL!
Has made my skin smooth again. I have always had adult acne and while I still have a few persistent spots, I can tell a big difference after a couple of weeks of using the retinal. The areas are finally getting smaller and less inflamed.

FAQ
CAN I USE VITAMIN A IF I HAVE SENSITIVE SKIN?
Vitamin A is suitable for all skin types but it can take some time getting used to, especially if you have sensitive skin. We recommend following a “retinal ladder” to allow your skin to get used to the ingredient. For the first two weeks, use the a lower-strength serum twice a week. For the next two weeks, apply every other night. Then move onto nightly application. After a few months, you can then upgrade to a higher strength serum.
WHEN SHOULD I USE CRYSTAL RETINAL IN MY SKINCARE ROUTINE?
Many professionals recommend applying vitamin A to clean, dry skin before bed followed by a moisturizer. This will help to offset any dryness that may occur as your skin adjusts to the product. For best results, we recommend including vitamin C and a high quality broad spectrum SPF 30 in your morning routine.
HOW SOON WILL I SEE VISIBLE RESULTS?
It can take anywhere from 4 to 12 weeks before you start to see the benefits of vitamin A. Your results will depend on the strength you’re using.
DO YOU TEST ON ANIMALS?
We strictly adhere to European regulations and do not test on animals or ask other companies to do so. Checking supplier compliance is integral to our product development process. We anticipate the global ban of animal testing.
