How to alleviate rosacea?
Rosacea being a chronic condition, there is no definitive curative treatment. However, a dermatologist can prescribe several soothing and calming treatments to reduce symptoms. If you suffer from rosacea, you can also take some additional precautions to prevent rosacea flare-ups.
Apply sunscreen.
The first step to take if you are suffering from rosacea is to apply a sunscreen every morning with an SPF of at least 50. If you must be exposed to the sun for extended periods, avoid direct radiation by wearing a hat and trying to stay in the shade. It has indeed been shown that the sun's UVB rays, which are very energetic, are likely to interact with the TRVP4 receptors in the epidermis, partly responsible for the deterioration of skin tissues. The stimulation of these receptors induces nociceptive mechanisms and an alteration of the skin structure.
Hydrate the face with a suitable skincare product.
A skin suffering from rosacea requires a gentle and soothing moisturizer to calm it down. The application of creams based on hyaluronic acid, for example, allows for deep skin hydration, while protecting it against external aggressions and free radicals. To supplement your skin's hydration, you can also use a care product enriched with bisabolol. This active ingredient, known for its soothing and healing properties, can alleviate the sensations of irritation and burning characteristic of rosacea.
Avoid trigger foods...
The consumption of certain foods is discouraged when suffering from rosacea. Indeed, studies have shown that spicy foods such as chili, pepper, or bell pepper are likely to interact with certain receptors that have nociceptive and inflammatory roles. It is also advised against consuming alcoholic beverages or foods high in histamine (tomatoes, citrus fruits...) or in cinnamaldehyde (cinnamon) in case of rosacea. These tend to have a vasodilatory effect and can cause hot flashes and the appearance of redness.
... and prioritize the consumption of certain foods.
On the contrary, the consumption of certain foods can be beneficial and reduce rosacea flare-ups. The caffeine in particular has vasoconstrictive properties that can help limit these episodes. Additionally, the vitamin B2, found in green vegetables and rice, and zinc, found in seafood and certain meats, stimulate certain signaling pathways that trigger anti-inflammatory mechanisms.
