Sweating is very less. Because of that?

Hi Doctor! I have been working out at the gym for a while. But compared to others, I sweat very less inspite of doing vigorous cardio exercises for more than 1.5 hrs. Also even during summer, I sweat very less compared to my family members. But my skin become oily sometimes inspite of having extremely dry skin. I use coconut and Nivea body lotion (with oil base) regularly to keep my dry skin moisturized. Is this a problematic condition? Should I take any test to resolve this? I have a skin condition of eczema since childhood and have been taking medications. Currently I have stopped since it was increasing my weight and switched to using topical creams. Is it because of that? Kindly clear my doubt. Thank you in advance!
