How does retinol work?

The process of retinol or retinoids in skin care is that retinoids will bind to retinoid receptors that are abundant in the epidermis. Then it will stimulate the expression of genes related to various skin processes, such as stimulating skin cell division, making the skin thicker, stimulating the synthesis of more collagen, especially collagen types 1, 3 and 7, inhibiting the enzyme that breaks down collagen and also helping to stimulate the synthesis of Glycoaminoglycan, resulting in more moisture in the skin.
In addition, retinoids have the ability to bind to abnormal or inflamed cells very well, such as areas with acne inflammation, which can reduce inflammation.
