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.
People may refer to their skin tone as uneven if they have patches or blotches of hyperpigmentation (darker or lighter patches) or redness across their face. This might include red streaks across the forehead, the tip of the nose and cheeks. It could also refer to age spots or sunspots, acne scars, or patches of dull and lifeless looking skin from aging or UV damage. Overly dry skin can cause damage to the follicles and production of collagen and sebum, which can cause the skin to appear duller or ashy.
To brighten the skin and provide a more even skin tone, it’s best to moisturize daily and wear sunscreen. Additionally, antioxidants protect the skin from free radicals that damage cells and speed up aging, which can cause dark spots and make acne scarring worse. Ingredients and nutrients like vitamin C, rumex, arbutin, rosehip oil, jojoba oil, retinol/vitamin A, coenzyme Q10, alpha-hydroxy acid and salicylic acid are all beneficial for evening out the complexion.
Since sun damage is the leading cause for uneven skin tone, it is important to wear sunscreen daily in combination with brightening ingredients.
DHA may be effective for uneven skin tone, 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.
