The most common side effect of topical corticosteroid use is skin atrophy. All topical steroids can induce atrophy, but higher potency steroids, occlusion, thinner skin, and older patient age increase the risk. The face, the backs of the hands, and intertriginous areas are particularly susceptible. Resolution often occurs after discontinuing use of these agents, but it may take months. Concurrent use of topical tretinoin (Retin-A) % may reduce the incidence of atrophy from chronic steroid applications. 30 Other side effects from topical steroids include permanent dermal atrophy, telangiectasia, and striae.
Yes, calisthenics can be progressed to be quite difficult. Planches and handstand pushups require a ton of stabilizer muscle strength and a ton of balance. This makes them rather impressive (and fun) … but the very thing that makes them impressive also makes them rather poor at building up muscle mass. Even with advanced progressions of bodyweight workouts the limiting factor will very rarely be mechanical tension in the targeted muscle, but rather stabilizer muscle strength and/or balance. As a result, your balance and stabilizer muscle strength will improve while your muscle size will remain more or less the same.
