Microneedling is effective for hair growth, especially when combined with finasteride and minoxidil, but concerns exist about potential long-term skin damage. Users report increased collagen and elastin deposition, but the long-term effects on the scalp remain uncertain.
Minoxidil can inhibit collagen production, potentially causing premature aging. The user is inquiring if Vitamin C serum or derma rolling can counteract this effect.
Minoxidil is discussed for its potential to decrease collagen production, with users sharing experiences about skin improvement after stopping its use. Some mention using it on their face for beard growth.
