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.
