While both are abbreviated as ALA, they are not the same. Alpha linolenic acid is a polyunsaturated fatty acid (omega-3) found in foods such as flaxseed, soybeans, pumpkin seeds, and walnuts. It helps support a healthy skin barrier and conditions the skin. On the other hand, alpha lipoic acid is a powerful antioxidant that can help fight the signs of aging, reduce the appearance of dark spots, and help prevent sun damage.
