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.
Dry skin, also called xerosis, is when the outer most layer of skin, or epidermis, isn’t retaining sufficient moisture. The epidermis is partially made up of epidermal proteins and fats, or lipids, which help to retain moisture. If the proper amount of these proteins or lipids are lacking, moisture will evaporate more quickly and dry skin will ensue.
Also, external and environmental factors, such as weather, cold air, hot and excessive showers and harsh soaps, are notorious for either causing or exacerbating dry skin.
Rosehip oil enhances the appearance of dry or damaged skin by reducing flaking and restoring the overall vitality of the skin. Jojoba oil is also good for keeping in moisture for healthier skin. Hyaluronic acid is another great ingredient for retaining moisture in dry skin.
Acne-prone dry skin is the hardest to treat because anti-acne ingredients like salicylic acid, glycolic acid, retinoid, etc tend to be drying. Instead of avoiding these effective ingredients, you can combine these ingredients with moisturizing ingredients to counter effect the dryness of these ingredients.
DHA may be effective for dry skin, 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.
