Acne, dryness, redness or fine lines... Skin concerns can affect both how we look and how we feel about ourselves. That is why a new ingredient presented with "proven benefits" draws interest. In this article, we take the skin care benefits claimed for CBD one at a time and show in plain language what kind of research stands behind each.

What does "proven" mean?

In science, a result is tested step by step through different kinds of studies. Roughly, they can be ranked like this:

Laboratory studies: Cells in a dish are exposed to the substance. They give the first clue as to whether there is an effect.
Animal studies: They check whether the effect is seen in a living organism.
Human studies without a comparison: A group of people use the product and the results are measured. However, it cannot be told whether improvement came from the product itself, happened on its own over time, or came from expectations.
Controlled studies: Participants are assigned to groups by chance; one group uses the product, the other uses a product that looks the same but has no active ingredient (placebo), and no one knows who is using which. These studies are the best way to show whether a product really works.
Analyses combining studies: The results of many controlled studies are brought together.

A claim can be called "proven" only when it is consistently supported at the upper steps. We explain how we grade evidence on our site on the evidence levels page.

Why are people curious about CBD in skin care?

Our skin also has a system that works with cannabinoid-like substances the body makes itself (the endocannabinoid system). This system is thought to play a role in healthy and diseased skin, and its disruption may be linked to conditions such as eczema and psoriasis (Río 2018). CBD (cannabidiol) is a non-intoxicating substance from cannabis, and because it can affect this system, it is attracting interest in skin research. A review of CBD's place in cosmetic dermatology also notes that laboratory data are promising but human studies are very few (Kuzumi 2024).

What does the research say? Claim by claim

Claim	Strongest study behind it	What did it show?
Oil balance, acne	Laboratory (Oláh 2014); 368-person controlled study (NCT03573518)	In the laboratory, oil production and inflammation decreased in oil gland cells. In people, no clear difference was seen between a CBD solution and a solution without CBD.
Psoriasis	Laboratory (Wilkinson 2007); 28-person controlled study (Roongpisuthipong 2026)	In the laboratory, the overgrowth of skin cells slowed. In people, CBD by mouth did not improve the disease score; itching decreased somewhat.
Eczema	57-person controlled study (Gao 2022)	No clear difference was seen between a cream containing only CBD and an inactive cream; a difference was reported for a cream combining CBD with another substance.
Itching	Analysis combining 17 studies (Sermsaksasithorn 2025)	A small reduction. Most of the products were not CBD alone.
Dryness, redness	Same analysis	No clear difference was seen.
Aging, antioxidant effect	Laboratory (Hampson 1998); 19-person pilot study (McCormick 2024)	Antioxidant effect in the laboratory. In 19 people, a CBD cream reduced some signs of UVA-related cell damage; wrinkles were not measured.
Sun protection	Laboratory (Hwang 2017)	Melanin production increased in skin pigment cells. No data in people.
Skin cancer	Laboratory and animal studies	There is no evidence that it prevents or treats cancer in people (details).

A note on two often-cited studies

An "86.4% reduction" in itching is often credited to a CBD cream. In that study, however, 22 people applied a cream containing not CBD but a substance found naturally in the body and linked to the cannabinoid system (PEA), and there was no comparison group (Ständer 2006). Similarly, the 20-person study describing a CBD ointment as "safe and effective" in psoriasis and eczema was retrospective and had no comparison group (Palmieri 2019). These studies give ideas for research, but they sit on the lower steps of the ladder above.

Products containing THC

There are very few controlled skin studies of products containing THC (the substance in cannabis that causes a high); some of the products in the combined analysis contained cannabis extract. There is not yet enough research on this.

Possible side effects and drug interactions

In controlled studies, CBD products applied to the skin were generally well tolerated. Plant extracts, fragrances and preservatives in the products, however, can cause irritation or allergy in sensitive skin; with some products, CBD can also pass from the skin into the blood. Details are in our article CBD oil and skin: side effects; for CBD taken by mouth, you can see the drug interactions page.

How was it used in studies?

Some of the forms used in the studies above (study doses, not personal recommendations):

Acne: solutions containing 2.5% and 5% CBD, once or twice a day, 12 weeks (NCT03573518).
Psoriasis: 60 mg of CBD oil a day by mouth (Roongpisuthipong 2026).
Eczema: a cream containing only CBD, 14 days; the CBD concentration is not given in the abstract (Gao 2022).
UVA study: CBD cream, twice a day, 14 days (McCormick 2024).

If you are thinking about using CBD

If you have a specific skin problem, the best place to start is talking with a dermatologist. During the visit, you can ask about:

Treatments for your concern whose effect has been shown in well-designed studies.
Whether it is appropriate to use a CBD product together with these treatments.
Whether the product contains ingredients that might irritate your skin.

In Turkey, cannabis-derived products, including CBD, may be sold only in pharmacies (Law No. 7557; regulation of January 31, 2026). Those classed as medicines or health products are dispensed with a prescription; the regulation does not state a prescription requirement for supplement products and cosmetics (personal care products) with a THC content of at most 0.3%. As of October 2026, there is no approved (licensed) CBD medicine in Turkey. Details are on the regulations page.

Conclusion

It is too early today to call CBD's skin care benefits "proven." Laboratory studies are interesting, but in controlled human studies, the most consistent finding is a small reduction in itching; in acne, psoriasis and eczema, products containing only CBD showed no clear difference. New studies are underway, and the picture may change over time. A current summary of the evidence in skin conditions is on our skin conditions and CBD page.

Frequently asked questions

Does CBD have any proven benefit for the skin?

It is too early to say 'proven' today. In an analysis combining controlled human studies, cannabis and cannabinoid products produced a small reduction in itching; there was no clear difference in dryness or redness. Controlled studies of products containing only CBD in acne, psoriasis and eczema also showed no clear difference.

Why aren't laboratory studies enough?

An effect seen in cells in a dish may not appear the same way with a product applied to the skin; how much of the substance reaches the skin, what the product contains and how the body responds are all different. That is why whether a product works is best shown by human studies in which people are assigned to groups by chance and compared with an inactive product.

Does CBD cream reduce itching by 86%?

That number has nothing to do with CBD. In the often-quoted study, 22 people applied a cream containing not CBD but a different substance called PEA, and there was no comparison group. In the analysis combining controlled studies, the reduction in itching with cannabis and cannabinoid products was small.

Does CBD protect against the sun?

In the laboratory, it increased melanin production in skin pigment cells and protected skin cells against UV damage; in a 19-person pilot study, it reduced some signs of UVA-related cell damage. However, there is no study showing it can be used in place of sunscreen.
