Congestion and sensitive skin is often a difficult combination to treat because part of treatment of congestion involves exfoliation and oil control which in itself drys the skin.
Treatment of clogged pores and blackheads involves exfoliation with:
1. Medical facials done by medical personal who is familiar with treating acne problems and sensitive skin at the same time
2. Skincare from doctors
Yes you should seek a dermatologist because it is important to be able to strike a balance between controling your acne and yet avoiding making your dry and sensitive skin worse. You need to find an expert who is good at doing so.
