I've had under the muscle implants for 1.5 years, "low plus profile" around 250cc. I have no complications and they're completely soft. The implants sit nicely and look completely natural. I'm thinking about going bigger, to 345cc or 375 moderate (allergan) responsive. Am I significantly increasing my risk of complication (specifically capsular contract) by going bigger in the same pocket? Will my body likely accept the new ones like the old ones? Any studies?
