Moisturizers and other semi‑solid skincare products are treated as liquids/gel by most airport security regimes. Each container’s labelled capacity must be 100 ml (3.4 fl oz) or smaller regardless of how full it is; containers exceeding this volume are routinely refused at security checkpoints. All permitted containers must fit together into one transparent resealable bag with a maximum capacity of about 1 litre (TSA’s 3‑1‑1 principle and equivalent EU rules).
Duty‑free purchases containing volumes above 100 ml are permitted through many airports only if supplied in a secure tamper‑evident bag (STEB) with an intact receipt; passengers with connecting flights through countries that re‑screen cabin items may face additional restrictions. Airlines and transfer airports apply local variations, so retain receipts and keep STEB sealed until final destination when applicable.
Medical and infant needs are exceptions in several jurisdictions: therapeutic topical products and baby feeding supplies that exceed 100 ml are often allowed but must be declared and may require inspection or supporting documentation (prescription, doctor’s note, or proof of necessity). For non‑medical larger containers, place them in checked baggage to avoid confiscation.
Practical packing recommendations: use containers clearly marked ≤100 ml or factory travel sizes, prefer squeezable tubes or bottles with screw caps and leak‑proof liners, double‑seal with small plastic bags if necessary, and position the resealable bag near the cabin baggage exterior for quick presentation at security. Verify specific airline and departure/transfer airport rules before travel; policies may vary by carrier and country.
What the 100 ml / 3.4 oz liquid rule means for facial moisturisers
Store all facial moisturisers, balms, lotions and other liquid or semi-solid skincare in containers of 100 ml (3.4 oz) or smaller and place them together inside a single transparent resealable bag with a maximum volume of 1 litre (approx. 20 × 20 cm).
Core limits and standards
- Per-container limit: 100 ml (3.4 oz) for each item classified as a liquid, gel, paste, lotion, aerosol or semi-solid.
- Bag limit: one clear resealable bag per traveller, maximum capacity 1 litre (≈1 quart).
- Presentation: remove the resealable bag from cabin baggage at security for X-ray screening where required.
- Geographic consistency: the 100 ml / 3.4 oz standard is applied across EU, UK and US checkpoints, though local enforcement details can vary.
Exceptions, borderline products and practical tips
- Medicated topical treatments and infant feeding items exceeding 100 ml are usually permitted but must be declared and may undergo inspection; carry a prescription or supporting documentation where available.
- Duty-free purchases packed in a Security Tamper‑Evident Bag (STEB) with receipt are generally allowed beyond 100 ml for travel through the same terminal; confirm acceptance for connecting flights before departure.
- Solid bars (cleansers, solid moisturisers) are not classed as liquids and do not count toward the 1-litre limit; balms and thick ointments often are treated as liquids–treat them as such when packing.
- Decant larger jars into properly labelled travel containers of 100 ml or less; use leakproof screw lids and seal caps with tape or plastic wrap to prevent spills during transit.
- For prescription or clinically necessary skincare over 100 ml, place the original packaging and prescription in carry documentation and present at security for verification rather than relying on memory.
- If uncertain about a product’s classification, assume it will be treated as a liquid by security staff and pack accordingly to avoid confiscation.
Quick checklist: transfer to ≤100 ml containers, label medications, use one transparent resealable bag (≤1 litre), keep duty‑free items in STEB with receipt, and verify rules for any connecting airports before travel.
How to pack jars, tubs and tubes to pass airport security (clear bag, lid checks)
Immediate action: Place jars, tubs and tubes upright inside a single transparent resealable quart-size bag (approx 20 x 20 cm / 1 L) and position that bag on top of cabin bag contents for separate presentation at security.
Leak-proof sealing: Press a square of cling film over each container opening before screwing the lid on; seal the lid seam with waterproof tape (Kapton or quality packing tape). For extra protection, put each container into a small zip-lock pouch, then place all pouches into the quart bag.
Tubes and squeezables: Expel excess air, roll from the bottom toward the cap and secure the rolled end with a binder clip or a strong strip of tape. Store tubes cap-down inside the inner pouch so pressure changes are less likely to force product out.
Large jars or heavy pots: Transfer required amounts into travel pots made of rigid BPA-free plastic; fill travel pots close to the brim to reduce trapped air expansion. Use pots with inner screw liners or tamper-evident seals; label each pot with product name and date.
Presentation at the checkpoint: Remove the transparent bag and place it in the screening tray separately and unzipped. Expect officers to inspect lids and, occasionally, to request opening a sample container; keep a clean spoon or spatula available to comply quickly without contaminating other items.
Damage control tips: Cushion jars between soft items (socks, washcloths) inside the cabin bag, place heavier containers at the bottom, and avoid overfilling external pockets where pressure or impact could force lids open.

Options when moisturizer exceeds 100 ml: transfer, checked baggage, or buy after security
Decant into travel-sized containers (preferred)
Primary recommendation: split the product into containers of 100 ml (3.4 fl oz) or smaller and label each with product name and fill date.
Use sterile single-use spatulas or a syringe (5–30 ml) for accurate transfer; glass mini-jars (30 ml) or PET bottles work best for viscosity. Leave 5–10% headspace to allow for pressure changes. Seal lids with a piece of cling film between lid and rim, then tighten to reduce leakage.
Recommended kit: 10 ml and 30 ml jars, a small funnel, a 10–30 ml syringe, permanent marker, masking tape for temporary labels. For oil-heavy formulas, line the lid with a thin O-ring or adhesive waterproof tape.
Checked baggage and airport purchases
If decanting is impractical (large jar, luxury packaging, sterilization concerns), place the original container inside checked baggage with these protections: double-seal in a heavy-duty zip bag, wrap in absorbent cloth or a padded pouch, position centrally surrounded by clothes to minimize impact. Expect some risk of pressure-related seepage or cosmetic separation at extremes of temperature.
Duty-free and airport shops sell full-size items after security; purchases over 100 ml will generally be accepted onboard only if presented in a tamper-evident sealed bag (STEB) with the original receipt visible and the seal intact. For connecting flights, confirm transfer rules at the next airport–some transit security checkpoints will re-screen liquids and may confiscate items not in STEB.
Alternatives when transport of the original product is undesirable: request manufacturer samples (5–15 ml), use solid-format substitutes (balm bars, solid moisturizers) which are not subject to liquid limits, or purchase a travel-specific formulation at the destination.
Prescription and medicated topical products: paperwork, labeling and security procedures
Present original prescription and pharmacy label at the security checkpoint; keep medicated topical products in their original packaging with patient name, drug name and dosage clearly visible.
TSA (United States): medically necessary liquids, gels and aerosols larger than 100 ml (3.4 oz) are permitted when declared at screening and accompanied by supporting documentation. Suggested paperwork: original prescription, pharmacy-dispensed label, and a dated clinician’s note stating medical need and daily dose. Allow extra time for inspection; separate these items for screening.
EU/UK and most international airports: larger volumes for medical use are generally accepted if declared to security staff and supported by documentation. Carry both originals and translated copies (English recommended). Security personnel may request to open containers or verify contents; having everything labeled reduces delays.
Controlled substances and restricted drugs: opioids, some stimulants and certain sedatives often require additional paperwork or prior authorization from destination authorities. Examples that frequently trigger special rules: morphine, codeine, methadone, methylphenidate, benzodiazepines. Check embassy or national health authority rules before departure; obtain any required import permits and a clinician contact number printed on the letter.
Label checklist: patient full name; generic and brand name of medication; strength (mg/ml); prescribed daily dose and frequency; prescribing clinician and clinic/phone; dispensing pharmacy and date dispensed. Keep a photocopy and a digital photo of documents accessible on a smartphone.
Security procedure tips: declare medicated topical products at the start of the screening lane or on the screening form where provided; place items in an easily removable container to allow opening for inspection; expect possible swab testing. If a dispute arises, request escalation to a supervisor and present documentation. Store excess quantity in checked baggage only after confirming destination import rules.

Differences between countries and airlines: spotting stricter rules and risks on connecting flights
Check security rules for origin, each transit airport and every carrier on the itinerary before departure; if any transfer requires an additional screening, transfer skincare jars to checked baggage or use sealed single-use travel containers to avoid seizure at the transfer checkpoint.
Transit scenarios with elevated risk: any connection that involves passing through immigration or reclaiming checked items exposes products to the destination country’s screening regime instead of the original airport’s rules; transfers that force a landside terminal change or entry into a visa-free transit area commonly trigger full re-screening.
Airports and carriers apply different treatments to duty-free purchases and sealed bags. Some hubs accept tamper-evident bags and receipts for onward carriage, while certain security teams will reopen sealed items during a transfer and treat them as ordinary cabin items. International-to-domestic connections frequently produce the highest confiscation rate because international duty-free allowances do not carry through domestic security.
Operational points to follow: confirm whether each connection requires security re-screening; keep receipts for any airport or onboard purchases in original sealed packaging; label all jars with ingredient lists and original caps; pack duplicates across checked and cabin stowage when feasible; allow extra connection time (plan +60–90 minutes) when transfers involve a separate security lane.
