Brother, you specifically stated dry skin as being a key challenge you are looking to remedy. On top of finding an Omega3 that you can assimilate, as it is important for all kinds of health reasons, also look in to Ceramides. Very good oral supplement for dry skin.
"The outer layer of skin, also known as the epidermis, is made up of naturally occurring fat called Ceramides. Ceramides are essential for the skin as they hold back the moisture underneath and prevent it from drying up. Although naturally occurring inside the skin, environmental factors like cold weather and air pollution can significantly reduce ceramide's concentration and effectiveness. This may lead to irritation, infections, and dry, rough, flaky, and inflamed skin."......Quora
All kinds of good brands out there. Just check web reviews and pick a solid one. Has helped a few members of my family within about a month of starting supplementation.
Note: Don't exceed recommended dosage. Having high circulating Ceramides can cause cardiovascular issues. Plenty of information out there via Google search to inform your decisions regarding this possible route.
