Renowned for its effectiveness on signs of aging and blemishes, retinol is also associated with risks of irritation and inflammation. This is why individuals with darker skin, who are sensitive to hyperpigmentation issues, are sometimes hesitant to use it. Is retinol suitable for darker phototypes? Let's explore the scientific literature together.

Can darker skin types safely use retinol?
Retinol is one of the most widely used molecules in skincare today. This is due to its versatile nature and proven effectiveness through numerous studies. Retinol is particularly valued for its antioxidant, exfoliating, depigmenting, and firming properties. Once applied to the skin, retinol undergoes two successive conversions to transform into retinoic acid, its active form. This then binds to specific receptors (RXR and RAR), accelerating cell renewal and stimulating the activity of fibroblasts, the dermal cells responsible for the synthesis of collagen, elastin, and hyaluronic acid. However, retinol also has a certain potential for irritation and inflammation, due to its tendency to increase the expression of MCP-1, IL-8, IL-12p40, and TNF-α in epidermal cells and fibroblasts, which are pro-inflammatory mediators.
It is therefore reasonable to question whether retinol, which can sometimes cause skin inflammation, is suitable for black skin, for which hyperpigmentation, often caused by inflammation, is one of the main skin concerns.

Individuals with fair skin have signs of hyperpigmentation.
Scientific studies on this topic are reassuring: retinol is a beneficial ingredient for black skin, which can help prevent and reduce hyperpigmentation marks. Indeed, by stimulating cell renewal, retinol accelerates the natural exfoliation process. This mechanism helps to remove dead cells from the stratum corneum that contain an excess of melanin, the cause of hyperpigmentation. It's important to note that retinol does not have a lightening effect and does not create differences between the areas where it is applied and the rest of the body: it simply helps to reduce hyperpigmentation, thus contributing to a more even complexion. The results of some scientific studies, conducted with individuals with a dark phototype, are presented below and show the compatibility and interest of retinol and retinoids in general for black skin.
Study | Protocol | Results |
---|---|---|
GUENIN & al. (2020) | 308 participants with dark skin and hyperpigmentation applied a 0.05% tretinoin lotion daily for 12 weeks. | The average scores for hyperpigmentation decreased from 0.8 to 0.6, as did the percentage of participants with moderate or severe hyperpigmentation (from 26.4% to 17.3%). No side effects were reported. |
HARRIS & al. (2020) | 262 participants with dark skin suffering from acne applied a lotion containing 0.045% tazarotene or a control daily for 12 weeks. | A reduction of 60.4% in inflammatory lesions and 57.8% in non-inflammatory lesions was recorded in the group that received the lotion. However, 15 participants experienced skin irritation. |
LANGTON & al. (2024) | Eighteen volunteers with dark skin were occluded at the arm with a patch containing 0.025% retinoic acid (for 4 days) or 0.3% to 1% retinol (for 12 days). | An improvement in melanin distribution and a remodeling of the dermis were observed, while no side effects were reported. |
The photos of two participants taken during the initial study conducted with tazarotene, a molecule belonging to the class of acetylenic retinoids, are displayed below and show significant progress. The first individual experienced an 80% reduction in inflammatory lesions and a 33% decrease in non-inflammatory lesions, while the second observed a 60% reduction in inflammatory lesions and a 46% decrease in non-inflammatory lesions.

Since there is no such thing as zero risk, it is advised for individuals with dark skin, as with all phototypes, togradually introduce retinol into their skincare routine to minimize any risk of hyperpigmentation. Furthermore, if it is a treatment prescribed by a dermatologist, it is crucial to strictly adhere to the recommended doses.
