Approaching Chemistry: is tretinoin the same as retinol

Most people want to pursue a more refined appearance. As we age and experience issues such as oil secretion, our pores become increasingly rough. Therefore, many skincare brands on the market have launched skincare products aimed at reducing pores and making our skin more delicate and youthful. The two most common components that appear in promotional messages are tretinoin and retinol. Is tretinoin the same as retinol? Let’s get the answer from this article.

Is tretinoin the same as retinol?

To put it bluntly, the answer is NO. Although they are all retinoids, they are not the same.

Introductions of tretinoin and retinol

1.Tretinoin

Tretinoin, also known as retinoic acid, is an active metabolite or derivative of vitamin A. Currently, retinoic acid drugs are generally divided into three generations based on their structure. It has a wide range of biological applications, including regulating cell proliferation, inducing cell differentiation, and apoptosis, and inhibiting malignant cell generation. It has been widely used in the treatment of various dermatological diseases, such as psoriasis, acne, hair follicle keratosis, etc., mainly including periodontal keratosis.

It can be used locally to treat skin diseases such as stubborn acne and sunburn. This form of vitamin A can stimulate cell renewal, thereby promoting pore opening and removing the bacteria that cause acne. It can stimulate the synthesis of extracellular matrix proteins in the skin, accelerate the formation of new connective tissue bands in the upper dermis, and increase the tension intensity of the wound site. Tretinoin does not affect on normal skin collagen synthesis. In addition, it has inhibitory activity on leukocyte chemotaxis, thereby exerting anti-inflammatory effects. It is often used in over-the-counter face creams designed to improve acne, as well as eye creams and essences designed to reduce signs of aging.

2.Retinol

A subtype of retinoid acid called retinol is vital to human health and plays a role in the development of retinal cells. Maintaining visual function in low light circumstances is crucial. In the meanwhile, retinol can increase keratinocyte multiplication, enhance keratinocyte metabolism in the epidermal layer, and increase the synthesis of additional materials like collagen and hyaluronic acid. Retinol causes less irritation than retinoic acid.

Applications of tretinoin and retinol

1.Applications of tretinoin

Firstly, tretinoin can aid in acne improvement. It has a reputation for clearing up acne that won’t go away. It can lessen apparent lesions and prevent the growth of new lesions, according to research. Moreover, it can help regulate sebum production and encourage skin cell regeneration.

Secondly, it can also lessen wrinkles. The use of retinoic acid cream topically has been shown to reduce wrinkles and roughness in patients, according to a New Zealand research. Lightening wrinkles is one of the most popular local applications for this medication. It has been demonstrated to encourage epidermal thickening and is frequently used to stop or reverse premature aging.

Furthermore, it also possesses strong anti-inflammatory qualities. Research indicates that tretinoin can lower inflammation and has immune-regulating qualities. Therefore, it has been combined with antibacterial agents such as erythromycin to form a combination therapy for treating acne.

Finally, it can promote healing. Research has shown that the effects of tretinoin include the treatment of irritating reactions, such as burning sensation and scaling. It can help remove acne scars. It promotes healing by increasing skin cell renewal, thereby promoting the growth of new cells.

2.Applications of retinol

Retinol is widely used in skin care products, and generally speaking, skincare products with retinol added can be sold at a better price.

Firstly, retinol has excellent antioxidant and scavenging effects on oxygen free radicals, and its use with antioxidant enzymes is more effective. Secondly, retinol also has an anti-aging effect, as it gradually transforms into retinoic acid in our body. In addition, retinol can also regulate cell proliferation and differentiation, and it is the only drug approved by the US FDA to reverse photoaging.

The most common side effects of tretinoin and retinol are dermatitis or skin reactions, including redness, burning sensation itching, dryness, and peeling, etc. More serious symptoms, including urticaria and breathing difficulties, may strike certain individuals. If this uncommon negative response happens, please discontinue using it right away. Since there isn't any sunshine to exacerbate skin sensitivity, using it at night might lessen the chance of negative responses.

Conclusion

Is tretinoin the same as retinol? The answer is NO. To sum up, the two are comparable and belong to the same family of retinoids. The two, nevertheless, are not interchangeable. Both can be used to prevent aging, enhance cell regeneration, lessen wrinkles, and other effects. Nevertheless, the former is more widely used.
