As we age, some people will develop a natural sunken upper eyelid, and even normal people will develop some slight sunkenness, which is normal. However, as we age, the sunken upper lids tend to become more pronounced, which is a state of aging, and the best way to deal with it is with fillers. The first filler material is hyaluronic acid, which can be given in one shot, but it will collect into a lump as the eyelid moves, which works well when the eyes are open, but a lump when the eyes are closed, which is very unattractive. Collagen has the same problem as hyaluronic acid. I think the best filler material, or autologous fat, we can open the orbital septum when doing double eyelids, use a block of fat for transplantation, and then put it on the upper eyelid, which is a common method we use when doing double eyelid repair, and you can also use fat from the armpit and other fat similar to the upper lid, but you can’t just take a fat from your body for filling, there are strict requirements for screening in this area. If I don’t want to do double eyelids but only want to fill in the upper eyelid hollows, what method should I use? One is fat gel and the other is granular fat. Fat gel is a tissue that has been further purified from fat and contains a variety of stem cells that are more refined than fat. After filling to the layer of ROOF fat, it is evenly distributed and will not collect, and the reaction is light, swelling is light and recovery is fast, and the survival rate is very high. The granular fat is relatively larger, the uniformity may be worse, and the post-operative swelling period is longer.
