DHA is short for docosahexaenoic acid, and it is an omega-3 fatty acid necessary in the process of brain development. DHA also has an important role in heart health, improving vision, and in reducing inflammation. It is also responsible for the health of cell membranes, which directly affects your skin. Healthy cell membranes will give you healthy, soft and moist skin, whereas a weak membrane would cause dry, sad-looking skin.
DHA can help you have reduced sensitivity to the sun’s ultraviolet rays, so you are not as likely to have hyperpigmentation and other sun damage. It can soothe some effects of dermatitis, including dry and itchy skin. DHA has also been found to help with skin healing, and there are studies that indicate it may prevent skin cancer.
The commonest form of DHA is a fish oil supplement. Taking these can have some side effects, including nausea, halitosis and heartburn. There is also a possibility that ingesting fish oil may reduce your immune system’s activity, or interfere with your medication. Consult your doctor before taking DHA supplements. Topical application of fish oil doesn’t have any downsides other than an unpleasant smell.
Rosacea refers to a redness of the face caused by a condition affecting the blood vessels in the face. It’s more common in middle-aged women with lighter complexions, although rosacea can affect anyone. The exact cause is unknown, though it is typically hereditary and not caused by pore clogs or skin infections. Many people mistake rosacea’s redness and bumpiness of the face for acne. Rosacea has no cure, and it can fluctuate in its severity from month to month.
There are a few ingredients that can help reduce inflammation associated with rosacea. For example, jojoba oil is good for reducing inflammation associated with certain conditions that cause redness. However, it is important to work with a dermatologist to determine the cause of redness on your skin to determine the right course of treatment if it is rosacea or a combination of concerns.
DHA may be effective for rosacea, but there are many other factors that may affect whether this ingredient would work on your skin or if there are better ingredients that may work for you. Take this skin quiz to find the best ingredients for your skin and build your skincare routine.
