Quick rule: Each liquid or gel container must be ≤100 mL (3.4 fl oz). All such containers go into a single clear resealable bag with total capacity up to 1 L (US equivalent: one quart-sized bag, ~946 mL). Remove the bag for screening at checkpoints.
Exceptions and solid alternatives: Solid face bars and soap are not subject to liquid limits and may sit loose in a cabin bag or a checked suitcase. Prescription medicines, infant formula and medical liquids over 100 mL are permitted when declared and presented for inspection. Liquids bought post-security (duty-free) that remain sealed in a tamper-evident bag with receipt usually travel outside the 100 mL rule, but retain the receipt for connections.
Packing tips: move larger bottles into travel-size containers labeled with exact volume, buy a travel kit at the destination, or place originals in checked baggage. Use leakproof travel bottles, tighten caps, wrap threads with tape and double-bag to prevent spills. Keep the clear resealable bag near the top of the cabin bag for rapid removal during security checks.
Screening notes and measurements: security officers may test or measure suspicious volumes; 100 mL = 3.4 fl oz. A typical resealable bag is about 20 x 20 cm (one-quart). Rules vary by airport and airline–verify regulations for the departure airport and any transfer points before travel to avoid confiscation or delays.
Face wash in hand baggage: pack under 100 ml / 3.4 oz and place in one clear resealable bag
Place face wash in individual containers no larger than 100 ml (3.4 oz) and group all liquid, gel and cream items inside a single transparent resealable bag (maximum 1 litre / 1 quart) for security inspection.
Screening rules – US & EU at a glance
- Each container: ≤100 ml (3.4 oz).
- Total liquids per passenger: one clear resealable bag (US: 1 quart; EU/UK: 1 litre).
- Gels, creams, lotions, aerosols and pastes count as liquids; solid bars of soap do not.
- Prescription topical medications and baby food/formula are exempt from the 100 ml limit but must be declared and separately screened.
- Duty-free purchases in sealed tamper-evident bags with receipt usually allowed even if >100 ml; keep the receipt visible for security staff.
- Pressurized or flammable industrial cleaners, bleach, drain chemicals and other hazardous substances are forbidden in the cabin.
Packing tips and practical checks
- Transfer products into travel bottles labeled with exact volume; use bottles stamped with 100 ml / 3.4 oz markings when possible.
- Use leakproof caps, add tape or a plastic wrap under the lid, then place bottles inside the resealable bag to contain spills.
- Prefer solid alternatives (soap bars, cleansing wipes) to avoid liquid limits; wet wipes generally accepted as non-liquid.
- For quantities above limits, place items in checked baggage or buy after security – keep duty-free bags sealed with receipt.
- If taking aerosols, verify airline policy; many carriers restrict or ban large pressurized containers in the cabin.
- At home, measure bottle volume with a kitchen measuring cup (100 ml ≈ 3.4 fl oz) before departure to avoid rejection at checkpoint.
- For outdoor trips where a wash station is needed, consider non-liquid options or compact gear; see best watwr tables with umbrellas for portable shade and table ideas.
Does the TSA 3-1-1 rule apply to liquid, gel, cream and foam facial products?
Yes – the 3-1-1 policy covers liquids, gels, creams, foams and aerosols for cabin bags: each container must be 3.4 fl oz (100 ml) or less, and all such containers must fit inside one quart-sized (≈0.95 L) clear resealable plastic bag.
Scope: items dispensed as a liquid, gel, cream, paste, foam or aerosol are treated under the 3-1-1 rule. Solid bar products are considered solids and are not subject to the liquid limit. Wipes and pre-moistened pads are generally fine without fitting into the quart bag.
Exact limits: individual container ≤ 3.4 fl oz (100 ml); all containers must fit comfortably in one quart-sized clear bag; one quart bag per passenger. Containers exceeding 3.4 fl oz must be placed in checked baggage or discarded at the checkpoint.
Exceptions: prescription medications, medically necessary liquids, breast milk and infant formula are permitted in quantities greater than 3.4 fl oz but must be declared to the TSA officer for inspection. Carry supporting documentation for prescriptions when possible.
Powders and dry products: powders in containers larger than 12 oz (350 ml) may require separate screening and could be subject to additional inspection; smaller powder containers remain subject to standard X-ray screening.
Aerosols and pressurized cans: subject to the same 3.4 fl oz limit in cabin bags. Larger personal-care aerosols may be allowed in checked bags but are restricted by airline and hazardous materials rules – confirm limits with the carrier before packing.
Packing tips: transfer to leakproof travel bottles labeled with volume (≤100 ml), seal caps with tape or use travel caps, place the quart bag near the top of the cabin bag for easy removal at screening, and double-bag higher-value items to prevent contamination from spills.
How to measure and label face-wash containers to meet 3.4 oz cabin-size limits
Recommendation: transfer product into transparent, leakproof vessels of ≤100 ml (≈3.4 fl oz), label each with product name, exact fill volume in ml and fl oz, and the fill date.
Exact measurement method: use a calibrated syringe or graduated cylinder for volumes under 100 ml; for larger batches use a digital kitchen scale (accuracy ±1 g). Conversion constants: 1 fl oz = 29.5735 ml, so 3.4 fl oz ≈ 100.5 ml – use a 100 ml container to stay within limits.
Weigh-to-volume technique: tare the empty container on the scale, add product, record gross weight, subtract tare to get net grams. For aqueous products assume density ≈1.00 g/ml (1 g ≈ 1 ml). For thicker gels/creams use density range 1.02–1.10 g/ml; if unknown, measure 10 ml sample on a scale to calculate exact density before filling multiple containers.
Pump and foam dispensers: measure pump output by dispensing into a 10 ml graduated cylinder; note ml per full stroke (e.g., 0.8 ml/stroke). Multiply strokes to reach the target volume and then transfer that total into the labeled bottle. Leave 5–10% headspace (5–10 ml for a 100 ml bottle) to accommodate pressure changes.
Label format and permanence: include: product name (e.g., “Face wash”), net volume (e.g., “100 ml / 3.4 fl oz”), fill date (MM/YYYY). Use waterproof printed labels or a permanent marker over clear tape; place label on the main body, not the cap. For multi-ingredient or homemade mixes add a short ingredient list and batch number if reusing containers.
Filling tools and hygiene: use a small funnel, transfer syringe, or spatula sanitized with isopropyl alcohol; avoid cross-contamination by dedicating tools to product families (water-based vs oil-based). Cap and wipe threads to ensure a leakproof seal.
Packing note: stow labeled bottles inside a transparent resealable bag (~1 quart / ≈0.95 L) to contain leaks and speed visual inspection.

Packing techniques to prevent leaks and speed up security checks
Store all liquids and semi-solid toiletry containers upright inside a single transparent, sealable pouch; secure each cap with a layer of plastic wrap pressed over the opening and taped around the thread, then place the pouch in an easy-to-reach exterior pocket of the cabin bag.
Leakproofing methods
Use rigid, BPA-free travel bottles with inner snap liners or pump dispensers that lock; apply two independent seals per container (inner liner plus external wrap). For extra protection, wrap each bottle in a thin absorbent cloth and place inside a secondary zip pouch – this prevents spread if a seal fails. For post-fill drying of bottles and small accessories, a compact indoor rack like best umbrella drying rack indoor works well to air bottles without drips pooling on surfaces.
Checkpoint-ready packing
Arrange the transparent pouch at the very top of the bag so security staff can lift it without rummaging; align labels to face the same direction and keep the pouch flat to avoid overlapping items on X-ray. Remove bulky cases that obscure contents and replace them with thin, structured pouches that retain shape during screening. If inspection is requested, hand over only the pouch rather than the entire bag to cut handling time.
What to do if a facial wash exceeds cabin allowance
If the bottle is larger than 3.4 oz (100 ml), the fastest solution is to place that full-size item in checked baggage or buy a travel-size replacement at the terminal before passing security.
Purchase options: airport shops and nearby pharmacies sell single-use sachets, 30–50 ml travel bottles, and bar-format cleansers. Duty-free outlets will issue tamper-evident sealed bags with receipt; retain the sealed bag and proof of purchase for connections that require it.
Solid substitutes: use a cleansing bar, oil-balm-to-solid formats, or pre-packaged micellar pads – these bypass liquid limits entirely and typically last 5–10 uses (bars often label grams; a 30–40 g bar equals several weeks of short trips).
Shipping ahead: if the full-size product is essential, ship via courier to the destination address with 2–3 day service; add basic insurance for high-value items and use crush-resistant packaging. For same-country shipments, USPS Priority or equivalent often delivers within 1–3 business days.
Checked-bag protection for expensive formulas: wrap in a resealable pouch, surround with soft clothing, place inside a hard-sided toiletry case, and add adhesive tamper tape across the cap. Photograph contents and keep proof of purchase for loss claims.
Medical or prescription liquids larger than 3.4 oz are screened rather than denied; present them to security officers for inspection, keep original labels and prescription/doctor’s note accessible, and allow additional testing if requested.
Short-notice alternatives at the airport: hotel or airline amenity kits, brand counters with travel testers, or vending machines in some terminals stocked with travel toiletries – these avoid the need to repackage or check items at the last minute.
How international and airline rules differ for cleansing products
Verify the airline’s toiletry policy and departure country’s security rules before reaching the airport checkpoint.
Common regulatory baseline and where it varies
Most civil aviation authorities enforce a 100 ml (3.4 fl oz) per-container limit and require all liquid/gel/cream/foam items to fit inside a single transparent resealable bag of roughly 1 litre (1 quart) for cabin baggage. Variation appears in three areas: transit processing, duty-free purchases, and exemptions for medical/baby supplies. Transit airports may re-screen and apply the originating or transit country’s rule rather than the point of sale; therefore a sale-compliant item at origin can be rejected during connection screening. Duty-free goods presented in a sealed tamper-evident bag with receipt are frequently allowed through the initial checkpoint, but acceptance during international transfers depends on the transit airport’s security procedures.
Airline-specific limits, hazardous-goods rules and practical effects
Individual carriers set additional restrictions beyond national security rules. Low-cost and regional operators sometimes forbid aerosols or limit total toiletry quantities due to cabin space or aircraft type. IATA/ICAO dangerous-goods rules impose net-mass and packaging requirements for pressurized containers; several airlines therefore cull large aerosol cans or require them in checked baggage only. Prescription topical medications and baby food are commonly exempt from the 100 ml cap but must be declared and presented for inspection, preferably with a prescription or receipt. Practical takeaway: for international itineraries confirm both the carrier’s dangerous-goods/toiletry page and each airport’s security guidance for departures and transfers, opt for pump or non-pressurised formats where possible, and retain receipts for duty-free or prescription items to speed up screening.
