Why beta-blockers cause skin inflammation

Researchers found that beta-blockers can cause psoriasis by interfering with the breakdown of defective cell components and disrupting autophagy. This leads to the release of inflammatory messengers, resulting in skin problems. The study suggests that fat-soluble beta-blockers are more likely to cause inflammation.
