Because of its capacity to permeate the stratum corneum and dermis of the skin, retinol has a variety of applications that can help skin health.
To aid in the treatment of acne
Acne is a common chronic skin disorder in which dead skin cells and glandular oils clog the skin’s hair follicles. Bacteria can get into these closed holes as well. According to a 2017 article, topical retinoids such as retinol help minimize abnormal skin peeling that plugs pores and unclog them. Retinol can also help to lessen inflammation by inhibiting the chemicals that cause:
According to a 2017 report, topical retinoids such as retinol help minimize abnormal skin peeling that clogs pores and unclog them. Retinol can also help to lessen inflammation by inhibiting the chemicals that cause it.
According to a 2019 systematic review, topical retinoids can effectively and safely treat acne. It also implies that a person’s topical retinoid dosage is more essential than the type of topical retinoid they take. In addition, retinoid therapy in conjunction with an antibacterial agent may increase acne treatment effectiveness, according to the review. A person with severe acne may require stronger retinoids, such as isotretinoin (a weaker retinoid), than retinol.
Skin aging can be caused by both biological and environmental causes, such as:
- UV light exposure
These can cause the skin to lose suppleness and the epidermal layer of the skin to store less water. According to the American Academy of Dermatology (AAD), visible indications of skin aging include:
- Fine lines
Skin aged by UV exposure may also display darker blotches on the skin, known as age spots. According to the 2019 study review cited earlier, retinol can protect against collagen breakdown while also stimulating cell turnover and collagen formation in the skin.
Retinol can also thicken the epidermis and lower the quantity of water that evaporates from the skin passively. This can make the skin appear plumper and help to decrease and delay the effects of aging. Topical application of retinol at a concentration of 0.4 percent resulted in enhanced epidermal thickness and better blood flow to the treated region of skin in a small 2017 research.
Collagen and elastin gene expression have also increased, according to the researchers. This shows that retinol enhances the dermis’ microenvironment. After 8 weeks of treatment, retinol enhanced the look of wrinkles around the eyes and on the neck, according to 2019 research. Short research published in 2016 examined the effects of retinol and retinoic acid.
Retinol has lesser effects but is still beneficial in boosting epidermal thickness and collagen expression, according to the study. After using retinol for more than 12 weeks, a facial imaging examination revealed a considerable reduction in facial wrinkles.
To improve the skin’s look
Because of its influence on cell turnover and collagen formation, retinol can help to improve the look of uneven skin tone and texture. It also has the ability to lighten the skin. Hyperpigmentation and unevenness were reduced in individuals who took retinol serums at dosages of 0.3 percent and 0.5 percent for 8 weeks, according to a small 2020 research.
However, people who took the 0.5 percent serum had greater symptoms, according to the study. The benefits of a 3% intensity retinol peel on participants, including persons of color, were explored in a 2019 research. The peel dramatically improved pigmentation and complexion, according to the research.
According to the experts, this therapy approach is safe and beneficial for persons with various skin types. However, the American Academy of Dermatology warns that persons of color, particularly those with a dark complexion, should exercise caution while taking retinol. It may irritate the skin, resulting in hyperpigmentation. The American Academy of Dermatology suggests that those who use retinol begin carefully and evaluate their results.
Retinol also has the following advantages:
- According to the American Osteopathic College of Dermatology, retinol can be used to treat keratosis pilaris, a condition that causes the skin to become rough and bumpy
- Retinol also strengthens and thickens the epidermis, which may protect the skin from external stresses such as pollution, according to research
- Retinol can also help to reduce the look of acne scars, according to the AAD. According to a new study from 2019, it can also help to reduce the appearance of pores
