Was advised over muscle as not a natural look fan, what's your view on over vs. under muscle implants?

Choosing between over or under the muscle for breast implants depends on the desired look and your body type. Over the muscle may appear less natural but has a simpler recovery. Under the muscle looks more natural and may have lower complication rates, but with a longer recovery. Your surgeon's advice seems tailored to your preference for a less natural look.

There are pros and cons to selecting to place implants over the muscle versus under the muscle and vice versa. Over the muscle implants have a little easier recovery. They also can give a more "obvious" augmentation look if desired. Under the muscle allows the upper portion of the implant to be disguised. This helps to hide rippling, wrinkling, or seeing the edge of the implant. Under the muscle also carries a lower incidence of capsular contracture and provides a more natural look.

Both above and below the muscle can be made to look very natural or very not-natural to fit your goals, depending on the size/profile of implant, implant cohesivity, and your breast and chest wall shape. If going above the muscle, I do think it's important to place the implant subfascial (a modern above the muscle technique), as opposed to subglandular (the old above the muscle technique). Subfascial gets less capsular contracture, gives a better upper pole contour, prevents rippling, and gives better longevity than subglandular.
