Does Dissolving Filler Cause Sagging? A Dermatologist Explains

Hi everyone, I'm Dr. Jane Yoo, board-certified dermatologist and Mohs surgeon. Today I want to answer one of the most common questions I get during filler dissolution consultations. If I dissolve my filler, will my skin sag? The answer has 2 parts, and I think people usually only hear one of them. Dissolving hyaluronic acid filler does not directly dissolve the collagen, elastin, fat, or ligaments that support your face. Hyaluronidase works by breaking down hyaluronic acid. What dissolving does is remove volume, and when you remove volume that has been present for a long time, especially a significant amount of it, the skin and surrounding tissues may temporarily look looser or more deflated afterward. So if you look in the mirror shortly after dissolving and feel like your skin looks lax, that does not necessarily mean the enzyme damaged your skin. You've removed volume that was previously supporting and stretching that tissue, and now you need to give the area some time to settle. Skin is viscoelastic, meaning it can stretch and adapt to changes in volume over time. We see this with things like pregnancy and changes in body weight, and the same basic principle can apply when facial tissues accommodate added volume. If you add a small amount of filler once, that may create relatively little change in the surrounding skin. But if you've been adding filler every 6 to 12 months for several years, especially without accounting for how much previous filler may still be present, you can gradually accumulate a significant amount of volume. Because that process happens slowly, you may not notice how much your appearance has changed over time. Then, if that volume is removed relatively quickly, the difference can look dramatic. That doesn't necessarily mean your skin has been damaged. You're seeing the tissue without the volume that had been filling it. How well that area settles afterwards depends on several things. The first is how much filler you had and how long it was there. Someone who has had a relatively small amount of filler for a short period of time is very different from someone who has accumulated a large amount of filler over the years. Age also matters. Our skin naturally loses elasticity as we age, so younger skin generally has greater elastic coil than older skin. Your baseline skin quality matters too. Chronic sun exposure, smoking, genetics, and the natural aging process all affect collagen and elastin, and therefore influence how the skin behaves after volume is removed. And then there's how the filler is dissolved. For patients with a large amount of longstanding filler, I often prefer staged dissolution rather than trying to remove everything at once. That may mean treating over multiple sessions and reassessing between treatments. It gives me much more control about how much product I'm removing and allows us to see how the face changes as we go along. Now, lips deserve their own discussion because saggy lips after dissolving filler is something I hear all the time. Lip skin is thin, and filler can change both the volume and projection of the lips. When that filler is removed, the lips can initially look smaller, more wrinkled, or slightly crepey compared with what you've gotten used to seeing. This can be especially noticeable if you've had filler for years, but again, What you see immediately after dissolving is not necessarily the final result. There may be temporary swelling and changes in hydration, and the tissue needs time to settle after the volume has been removed. There's also a psychological adjustment that I think gets overlooked. If you've been looking at fuller lips every day for 5 or 6 years, your natural lips may suddenly look extremely small to you, even if they simply return closer to their baseline. In patients who have had very large amounts of filler for many years, particularly when there has been significant migration into the skin above the lip, some persistent laxity may remain. I think it's important to discuss that possibility before dissolving rather than promising that every patient will return exactly to their pre-filler appearance. So, what actually helps after dissolving? The biggest thing is time, which unfortunately is also the answer nobody wants to hear. If there is a lot of filler, staged dissolution may be appropriate, and throughout the process, protecting your skin from the sun is important for maintaining overall skin quality. Once the area has completely settled, if there is true residual skin laxity, then we can have a separate conversation about treatments that target skin quality and collagen rather than simply replacing the volume with more filler. Depending on the patient and the area, that could include certain energy-based treatments such as microneedling with radiofrequency or other collagen-stimulating treatments. What I would not recommend is panicking a few weeks after dissolving and immediately putting filler back in because you think you look too loose or too hollow. If you refill an area while it is still changing, you may be treating a temporary appearance rather than your actual baseline. That can put you right back into the cycle of repeatedly adding more volume. I'm also skeptical of treatments marketed specifically as ways to massage migrated filler away or dramatically accelerate filler dissolution. Lymphatic massage may temporarily help with swelling in certain appropriate situations, but it does not replace hyaluronidase when hyaluronic acid filler actually needs to be dissolved. And topical skincare products cannot dissolve injected hyaluronic acid filler. Ultimately, I want patients to give their face enough time to settle before deciding that any change is permanent. I don't like promising that everyone will look a certain way by 3 months or 6 months because recovery is individual and we don't have strong evidence establishing a universal timeline. If you continue to have laxity after everything has settled, then that's something we can actually evaluate and treat. At that point, we're looking at a much more stable baseline rather than trying to correct a face that is still changing after dissolution. So, will your skin sag after dissolving filler? It can temporarily look looser or more deflated after volume is removed, and some patients with significant long-standing filler may have residual laxity. But that is very different from saying that hyaluronidase itself dissolves or destroys the structures that support your skin. The goal is to remove only what needs to be removed, give tissue time to settle, And then decide whether anything else actually needs to be treated.
