what helps under eye bags
The safest non-surgical treatment of under eye bags, dark circles and hollows are Hyaluronic Acid Gel fillers. This class of fillers includes Restylane, Belotero, Juvederm, Perlane, Voluma and others. They are all the same product, just made up of different consistencies (ie. density, thickness, flow, etc).
If the technique is good, this is less of a concern. In most cases, under eye bags are treated with a surgical procedure called blepharoplasty. This procedure can be done sometimes with an incision inside the lower eyelid and could be considered minimally invasive even thought in theory it is surgery.
