Gecko Shedding & Stuck Shed First Aid: Signs to Treatment

Shedding is a normal part of a gecko's growth: new skin replaces old. Juveniles grow almost weekly and shed often; adults shed once or twice a month. Most of the time shedding is so quiet you miss it — the gecko eats the skin itself. But when humidity is wrong, the shed "sticks" and you get stuck shed (incomplete shedding). This article covers the full path from early signs to first aid.

1. Four signs before the shed

Your gecko will not announce "I'm about to shed," but its body will. One to three days before, it usually shows: first, its colour turns pale grey and dull, as if covered in fog; second, it slows down and stays in its hide; third, appetite drops or stops entirely; fourth, it rubs against the enclosure walls and substrate, trying to loosen the old skin. See these four signals and you can start preparing the shedding environment.

2. The three "don'ts" during shedding

Three things to avoid while your gecko sheds: don't force handling (the skin is sensitive; grabbing can tear the new skin underneath); don't peel the old skin (it should come off naturally — pulling it off takes the new skin's keratin layer with it and causes wounds); and don't feed (digestion competes with the energy needed for shedding, and appetite is low anyway). All you need to do: set humidity to the species' range (e.g. 40–60% for leopard geckos, 60–70% for crested geckos) and place a moist shed box — a hide lined with damp paper towel or damp moss — then wait.

3. What stuck shed is, and why it happens

Stuck shed means the old skin did not come off completely and remains in patches. The most common places are the toes, tail tip, eyes and head. The cause is almost always humidity: below 30% for long periods, the old skin dries hard, loses elasticity and cannot release. Stuck shed is more than ugly: a ring of old skin around a toe keeps tightening, blocking circulation until the toe tip dies and falls off; skin over the eye blocks vision, and long-term neglect can damage the cornea.

4. The 48-hour first-aid process

When you find stuck shed, work through this process (complete it within 48 hours):

1. Step one (0–12 hours): prepare a shed box — a small tub lined with damp (not dripping) paper towel or moss. Put the gecko inside and leave it in a warm spot for a few hours. The humidity softens the stuck skin, and many mild cases resolve here by themselves.
2. Step two (12–24 hours): if skin still remains, dip a cotton swab in warm water (about 25–28°C, warm to the touch), and gently wipe along the edge of the stuck skin to soften it layer by layer. Wipe only — never peel; wait for it to loosen.
3. Step three (24–48 hours): for a toe ring that still will not come off, use tweezers to lift one side very gently and roll it off with the swab. If any step meets strong resistance or the skin is stuck fast, stop, and keep waiting in the moist environment.

Throughout: "wet + soft + gentle" is the core. Any "force" is wrong.

5. When you must see a vet

Do not treat these yourself: stuck skin over the eye for more than 24 hours that you cannot safely manage; redness, discharge or necrosis (blackening) around the stuck area; stuck shed recurring for over two months; or the gecko has stopped eating and is lethargic. Eyes and necrotic tissue need professional veterinary care — DIY attempts can cause permanent damage.

6. Use records to stop repeating the mistake

Stuck shed is an environment problem, not a luck problem. After every shed, log one line in the Shedding Checklist (date, went well or not, humidity at the time). After a few entries you will see the pattern in your own setup: whether humidity collapses during winter heating season, or whether the shed box was prepared too late. Records are not a chore — they are the only way to make the next shed problem-free.

Behind every gecko that sheds perfectly is an environment with stable humidity. First aid treats "this time"; fixing the environment treats "next time."
