Hand rejuvenation: what changes on the back of the hand?

Three separate things age at once on the back of the hand

Along with the face, the back of the hand is one of the areas most exposed to the sun over the years, and it has one of the thinnest cushions of soft tissue underneath. This is why ageing in the hand cannot be reduced to a single change.

Research looks at ageing of the back of the hand under three separate headings. The first is volume loss: the fat tissue under the skin decreases (soft tissue atrophy). The second is the quality of the skin itself: the skin loses its elasticity, becomes thinner and turns translucent. The third is colour: dark spots and uneven skin tone related to long-term sun exposure.

This distinction matters because each component is addressed with different methods. A treatment that restores lost volume does not remove a dark spot; a treatment aimed at pigmentation does not make the tendons less visible; and a treatment that targets the skin tissue does not fill a hollow back of the hand. All three can be present in the same hand, but they do not need to be treated at the same time or with the same method.

Volume loss: why tendons and veins become more visible

As the hand ages, the skin loses its elasticity and becomes more translucent; the blood vessels (veins), joints and tendons look more prominent, and bony ridges become noticeable. Research links this picture both to the body’s own ageing process and to external factors.

It is important to understand which way the change goes. The veins do not get thicker and the tendons do not grow larger; the cushion under the skin that covers them gets thinner. The structures stay where they are; they are simply less covered than before. So if volume loss is the main issue, the aim is not to make the visible structures smaller but to support the layer of soft tissue over them. This is also why research on age-related change in the back of the hand puts the emphasis on replacing lost soft tissue volume.

How that volume is replaced is a separate question. First, this component needs to be told apart from the other two: what makes a hand look hollow is not the colour of the skin but the empty space under it.

Skin quality: thinning and elastosis

The second component is the skin itself, and it progresses independently of volume loss. Long-term exposure to ultraviolet (UV) light damages the supporting tissue (extracellular matrix) in the dermis, the layer beneath the skin’s surface layer: collagen breakdown increases, the structure of the elastic fibres changes, and a build-up called solar elastosis forms in the dermis. Recent research on sun-related skin ageing (photoageing) looks at this process together with the colour changes that accompany it.

At an advanced stage, this is no longer a cosmetic problem. This state, in which the skin becomes fragile and can no longer adequately perform its functions, is called dermatoporosis; it is a recognised clinical condition. In a study that measured forearm skin, people with dermatoporosis were reported to have a markedly lower combined thickness of the skin’s surface layer and the dermis than healthy volunteers, and fewer dermal papillae (the projections that connect these two layers). The study also reported that the thickness of elastosis in the dermis was one of the main measurements that distinguish this condition. The visible signs of this are star-shaped marks that look like scars (stellate pseudoscars) and easy bruising.

This finding comes before any decision about treatment. Skin that tears and bruises easily needs to be discussed separately when injections are being planned, and only a consultation can establish whether your skin is like this.

Pigmentation: dark spots are a separate issue

The third component is colour. The brown spots that appear on the back of the hand with age and long-term sun exposure are called actinic lentigines.

These spots are not caused only by excess melanin (the pigment that gives skin its colour). One study found a persistent inflammatory environment in the affected skin compared with the healthy skin around it: the arachidonic acid and plasmin pathways were activated, the cytokines that suppress inflammation were reduced, and the number of immune cells (macrophages and T cells) in the dermis was increased. The researchers concluded that this inflammatory cycle needs to be broken to make treatment of the spots more effective.

The second important point is the differential diagnosis, that is, telling the spot apart from other conditions that look similar. Dark patches that appear later in life (acquired hyperpigmentation) are not a single condition; they develop through different mechanisms and are regarded as separate diagnoses. It is not possible to say which condition a spot on the back of the hand belongs to without seeing the spot. This is a medical step, not a cosmetic one, and it is always the first step when the concern is colour.

Methods aimed at pigmentation form a group of their own: products applied to the skin (topical products), light and laser treatments, and peels. These methods are considered when uneven skin tone is the main issue. Research also looks separately at the role of sun protection in preventing colour changes.

The layers of the back of the hand: where the needle goes

The back of the hand is not a flat surface but a layered structure, and the safety of an injection depends directly on knowing these layers.

An anatomical study that combined cadaver examination, tissue examination (histology) and ultrasound showed three layers of fat (laminae) on the back of the hand, from the surface to the deeper tissue, and the membranes that separate them (fasciae). The same study found another fascia that had not been described before: this membrane divides the middle layer in two, leaving the network of veins on the back of the hand (the dorsal venous plexus) in the superficial compartment and the nerves that carry skin sensation (the dorsal cutaneous nerves) in the deep compartment. In other words, contrary to what had been assumed, the network of veins and the sensory nerves do not run in the same layer.

Researchers who have looked at the anatomy and the treatment options together agree on this point: the appropriate place for a volumising material is probably the superficial layer, which is relatively free of anatomical structures. This is not a strict rule but a shared view, and it is based on what that layer contains.

A study carried out at more than one clinic, which assessed patients with high-resolution ultrasound after treatment, points the same way: in back-of-hand treatments with different materials, the injected material was found above the tendons that straighten the fingers (the extensor tendons) in every case. However, the researchers note that these results should be interpreted with caution because the number of patients was small and the follow-up period was short.

Classes of material used to add volume

The materials used to add volume to the back of the hand are not a single group; they work in at least three different ways.

The first is taking up space. Hyaluronic acid (HA) fillers create volume in the layer where they are placed. An ultrasound study of 20 people reported that, after a single treatment into the superficial and middle layers, soft tissue thickness increased, skin roughness decreased, and the veins and tendons became less visible during follow-up. However, this study was small, with a single group and no control group; no general conclusion about how long the results last or the number of sessions can be drawn from it.

The second is stimulating the tissue. Research on calcium hydroxylapatite (CaHA) reports that it increases cell proliferation, collagen production, the formation of elastic fibres and elastin, and the formation of blood vessels; however, most of these studies have methodological limitations, and the evidence remains limited. In controlled clinical studies, calcium hydroxylapatite used in the back of the hand has also been associated with improvement on scales that grade the appearance of the hand, but heterogeneity (variation between studies) is high. Poly-L-lactic acid (PLLA) and its mixtures are also among the materials used in the back of the hand.

The third is transferring the person’s own fat: volume is replaced not with an external material but with tissue taken from the person themselves. This makes it a method in its own right, requiring an area from which the fat is taken (the donor site) and a separate procedure. To confirm the results in this area, studies are needed that measure volume objectively and follow people up over a long period.

These three approaches do not fill the same gap: one replaces volume directly, one stimulates the tissue’s own production processes, and one moves the person’s own tissue. Which of them may be considered for you is assessed at a consultation.

What the approved uses say about the back of the hand

The US Food and Drug Administration (FDA) explicitly includes the back of the hand when it lists the approved uses of soft tissue fillers: adding volume to the lips, cheeks, chin and back of the hand.

But the distinction does not end there. The FDA defines two groups separately: fillers that the body absorbs (temporary) and fillers that it does not absorb (permanent). Absorbable fillers are approved for adding volume to the areas listed above. Non-absorbable permanent fillers, by contrast, are approved only for the lines running from the sides of the nose to the corners of the mouth (nasolabial folds) and for acne scars on the cheeks. In other words, adding volume to the back of the hand is not among the approved uses of permanent fillers. This is why the class of material to be used on the back of the hand is a decision in its own right.

In the same text, the FDA points out a further limitation: the approvals are based on controlled clinical studies in which the products were used in the face or hands. These studies did not assess the use of these products together with other treatments, or the safety of repeated treatments.

This framework is the FDA’s own definition. In Türkiye, regulating and overseeing these products is the responsibility of a separate authority, and what a product may be used for is stated in the approved product information for that product. What is described here is the distinction between classes of filler, not individual products.

Injections for skin quality are different from volume treatments

Adding volume and targeting skin quality are not the same goal, and they are not done with the same technique. When adding volume, the material is placed in a layer under the skin where it will take up space. When skin quality is the target, small amounts are spread within the skin itself, in the dermis; the aim is to target the tissue itself.

Research on renewing areas other than the face (the neck, décolletage and hands) with injections treats these two approaches as separate topics and, alongside fillers, also looks separately at methods such as mesotherapy and microneedling.

The body of evidence for these areas appears to be more limited than for the face: researchers say that a comprehensive review is needed for areas other than the face. For this reason, no figures are given here for the back of the hand on the number of sessions, the size of the expected change or duration. What mesotherapy is and what it targets are explained on the Mesotherapy page.

Risks specific to the back of the hand

The back of the hand cannot be approached as a small copy of the face; it has risks of its own.

The first is anatomical. The network of veins on the back of the hand (the dorsal venous plexus) and the sensory nerves (the dorsal cutaneous nerves) run in layers close to the surface, and the anatomical study showed that these two structures lie in separate compartments; directly beneath them run the extensor tendons and their sheaths. Injecting into the wrong layer means coming across structures that are different from those in the face.

The second is functional. Among the common risks the FDA lists for fillers, there is one item specific to the back of the hand: difficulty performing movements, which is stated to occur only after injections into the back of the hand. Unlike the face, the hand is used all day long; this is why swelling (oedema) and tenderness here directly affect how the hand works.

The third relates to the person themselves. The FDA states that if adding volume to the back of the hand is being considered, any joint, tendon or blood vessel conditions affecting the hand should be discussed separately with the doctor. This is not a list that rules out treatment outright; it is something that should be asked about explicitly at the consultation.

Which findings point to which type of treatment

The choice starts with your hand, not with a method. Which of the three components is dominant determines which methods are discussed.

Treatments that replace volume are considered when the tendons and veins are prominent, the back of the hand looks hollow and the skin is still in relatively good condition; in other words, when what is mainly missing is the soft tissue covering.

If thinning skin, fine wrinkles and declining tissue quality are the main issues, approaches that target the tissue itself are considered. If easy bruising and fragile skin are also present, this is no longer a cosmetic matter, and it is assessed medically first.

If uneven skin tone and dark spots are the main issues, methods aimed at pigmentation are considered; here, the first step is not choosing a method but seeing what the spot is.

In most hands, all three are present together, and which one stands out varies from person to person. Which one to start with, which comes next, or which is not needed at all does not follow a single rule. This page cannot tell you which one is dominant in your hands; a consultation will show that.

Treatments offered here for the back of the hand

At this clinic, the treatments carried out on the back of the hand are adding volume with hyaluronic acid (HA) fillers and collagen-stimulating fillers, and mesotherapy. Which of these may be considered is assessed at a consultation, based on which of the three patterns described above is dominant.

The scope of filler treatments for areas of the body is explained on the Body Fillers page, and what mesotherapy targets is explained on the Mesotherapy page; this article focuses only on what changes on the back of the hand.

Looking at your hand and telling which of the three components is most prominent is your doctor’s job. Whether or not to have a treatment for that component is your decision.
