Retinal is a form of retinoid. Retinoids are the gold-standard class of anti-aging ingredients.

Retinal has many benefits as other retinoids: improve skin texture, reduce large pores, reduce the effects of aging, reduce the visibility of dark spots, heal scars, and fight acne.

Studies show retinal may work at a faster rate than retinol due to its structure.

All retinoids have to be converted into retinoic acid before starting to work. Some retinoids take several steps of conversion before binding. Retinal is only one step away, making it more potent.

Like other retinoids, retinal may be irritating. It is best to ease into using this ingredient frequently.

Using the 'ramp up' method, start by using retinol once a week. This gives your skin time to adjust and decrease irritation. Once you feel ready, you can slowly increase the frequency of retinol use.

Using retinoids will increase sun-sensitivity in the first few weeks of use. Though studies show retinoids increase your skin's natural SPF with continuous use, it is best to always wear sunscreen and sun-protection.

This is a very effective product at an incredible price point. It has a bright lemon yellow colour that will stain your skin for the night, as well as your pillowcases, but washes out. I use it every second night and have seen significant improvement in the fine lines on my face since I started using it about 4 weeks ago. One and a half pumps does my whole face. I've experienced no retinization symptoms from either retinoid emulsions that I've used from The Ordinary, and prior to the using them I had never used a retinoid, and I believe that the emulsion is an effective yet gentle delivery method.
I really like the pump that the Retinal 0.2% is sold in. The product is light safe and doesn't need to be kept in the fridge.
