Blueberries have become popular as a healthy fruit for the skin. Due to its concentration of vitamins, minerals and antioxidant compounds, some include them in the diet to reduce the risk of premature aging. Its extracts are used in the production of cosmetic products for skin care.
Even, due to their content of substances such as anthocyanins, they seem to help fight inflammation, psoriasis and the symptoms of other common dermatological disorders. Are you interested in identifying more about it? Next, we will tell you what benefits are attributed to it and how to use them.
Benefits of blueberries for the skin
Blueberries are wild fruits that grow in cool parts of the Northern Hemisphere. They are popular in what has to do with gastronomy since they are used in the preparation of jams, desserts, cakes and many other recipes. Also, they stand out in folk medicine.
Due to their important concentration of nutrients, they are a highly recommended food for the diet. In particular, as compiled by an article published in the International Journal of Molecular Sciences, they concentrate significant amounts of vitamin C, fibre, and phenolic compounds.
These substances not only reduce the risk of diseases but also promote the health of the skin. Either through its consumption or its topical application, they contribute to maintaining a healthy complexion, free of imperfections and with a youthful appearance. Let’s see in detail the benefits attributed to them.
1. Decrease the risk of premature aging
The exposure to free radicals from the environment can cause signs of premature aging, such as age spots, wrinkles and dry skin. As the years go by, the body diminishes its ability to deal with these harmful molecules. Also, factors such as sun exposure, tobacco smoke and pollution increase its impact on the skin.
Blueberries, by concentrating on antioxidant substances such as vitamin C and anthocyanins, inhibit the action of free radicals on cells and provide a protective effect against the damage they cause to the skin.
A study published in the Journal of Drugs in Dermatology determined that topical application of a matrix containing antioxidants from blueberries can protect the skin from wrinkles.
2. Help spur collagen synthesis
Collagen is an essential substance for the health and beauty of the skin. Over the years, its production is also reduced. However, including foods such as blueberries in the diet reduces their degradation and stimulates synthesis in the body. The reason? The content of anthocyanins and vitamin C.
In a study published in Molecular Nutrition and Food Research, cranberry anthocyanins helped reduce collagen breakdown. Also, they were shown to be effective in mitigating UV-induced photoaging.
Also, a cup of blueberries provides up to 19% of the daily needs of vitamin C. This micronutrient, apart from acting as an antioxidant, is essential for optimal collagen production and healthy skin.
3. They stimulate the healing of superficial wounds
Blueberries are not a first-line treatment for treating superficial wounds on the skin. Still, including them in the diet can contribute to the healing of minor cuts, minor burns or blemishes. Its content of vitamins C and K, as well as other antioxidants, support the recovery process.
It should be noted that it is not convenient to apply blueberries directly on the wounds, as this can lead to an infection. To take advantage of their benefits for this purpose, eating them for breakfast or a snack is enough.
4. They contribute to the treatment of acne
Today, dermatologists can suggest various types of acne treatment, depending on its cause. However, at a general level, it is recommended to improve your diet and consume those ingredients that provide antioxidants and fibre, such as blueberries.
While it is true that these berries do not cure acne as if by magic, their intake is an adjunct to reduce inflammation and act against the bacteria that cause this problem.
5. They can help against psoriasis and eczema
Psoriasis and eczema are skin diseases that must be addressed by the dermatologist. They are considered inflammatory and tend to cause dryness and flaking. Although there are many causes associated with its appearance, a risk factor is low levels of antioxidants.
Blueberries, being a source of these substances, can be a complement to reduce outbreaks and their symptoms. Although evidence is lacking to determine the role they play in these diseases, they are generally considered beneficial.
How to take advantage of the benefits of blueberries for the skin?
Blueberries are usually available in the market throughout the year, both fresh and frozen. Their incorporation into the diet is simple since they are versatile and give a delicious flavour to smoothies, salads, yoghurt and other preparations.
Eating them is the best way to obtain their benefits for the skin, as they provide the body with significant amounts of nutrients and antioxidants. Still, there are topical treatments that contain its extracts, such as cleansers, serums, creams, and masks.
In any case, direct application of the fruit to the face is not recommended, as it contains a strong pigment that can cause temporary blemishes. Even if they are rubbed on diseased skin, they are irritating. The best thing is always to consult with the dermatologist.
