Shedding is a normal and essential process for leopard geckos. But when the shed doesn't come off cleanly or completely, it becomes a problem that requires prompt attention. Retained shed — called dysecdysis — can become dangerous quickly.
The Normal Shedding Process
A healthy leopard gecko will shed completely within 24–48 hours, usually in one or two sessions. Before shedding, the skin will look dull or slightly milky. After a successful shed, the gecko will typically eat the shed skin — a normal behavior. Eye caps (spectacles) also shed during this process.
What Is Retained Shed?
When the shedding process doesn't complete normally, pieces of old skin remain attached. The most dangerous locations:
- The toes — retained shed constricts blood flow and can cause the toe to die and fall off (necrosis) if not removed
- The tail tip — same circulation risk
- The eye caps — retained eye caps prevent clear vision and can lead to eye damage
- The body — less immediately dangerous but indicates an underlying problem
Why It Happens
Low Humidity — The Most Common Cause
Leopard geckos need 30–40% ambient humidity with a humid hide available at all times containing moist sphagnum moss or damp paper towel. If the environment is too dry, the shed dries out before the gecko can remove it.
Poor Health or Nutritional Deficiency
Vitamin A deficiency, metabolic bone disease, dehydration, or illness can all impair normal shedding.
Stress or Recent Illness
Stress from handling, temperature fluctuations, or a recent illness can disrupt the shedding process.
How to Help Safely
If you find retained shed:
- Prepare a soak: Place the gecko in a shallow dish of lukewarm water just deep enough to cover their legs — for 10–15 minutes to soften retained skin
- Gentle removal: After soaking, use damp cotton swabs to very gently roll or dab at the retained shed
- Never pull retained eye caps — this can damage the eye; a vet should handle this
- Provide a humid hide: Moist paper towel or sphagnum moss inside a small hide — the gecko rubs against the walls to naturally remove shed
Do not try to pull off retained shed without softening it first. This causes pain and can damage the underlying skin.
When to See a Reptile Vet
- Retained shed on toes or tail tip that doesn't come off within 1–2 soaking sessions
- Retained eye caps
- Any signs of infection (redness, swelling, discharge) in shed areas
- Gecko refusing to eat alongside shedding problems
