A 2024 evidence review in Ophthalmology and Therapy puts the target at an eyelid temperature of \u003cstrong\u003eat least 40°C\u003c\/strong\u003e, held for \u003cstrong\u003eat least 10 minutes, once daily\u003c\/strong\u003e — once daily deliberately rather than more often, because adherence falls as the frequency rises. That is where most warm compresses fail: a hot towel or facecloth holds the eyelid above 40°C for only the first minute and drops below target within two minutes, so you would have to reheat it every two minutes for the whole session; and a microwave mask starts too hot and is lukewarm by minute eight, precisely when the treatment should be working hardest.\u003c\/p\u003e\u003cp\u003eiFlo is USB powered, so it does not cool through the session. It reaches up to 44°C across three heat settings — comfortably above that 40°C threshold and held there for the full cycle — warms in under a minute, and heats the upper and lower lids at once. That external heat is the whole point: normal meibum melts across roughly 19–45°C, and in MGD the thickened meibum sits at the top of that range, often above body temperature (37°C), which is why body heat alone never clears a blocked gland.\u003c\/p\u003e\u003cp\u003eThe part we actually dispense it for is the timing. iFlo prompts you to blink hard at eight and ten minutes, then signals the end of the cycle at twelve. Heat softens the meibum, but something has to move it out of the gland, and that something is a forceful, complete blink. People who warm their lids and then simply take the mask off have done half the treatment. The mask remembers the other half for them.\u003c\/p\u003e\u003cp\u003eUse it once a day for the full twelve-minute cycle — comfortably past the ten-minute minimum — follow with \u003ca href=\"\/collections\/lid-hygiene-blepharitis-nz\"\u003elid hygiene\u003c\/a\u003e, and give it six to eight weeks before judging it, though most people notice a difference within two to three weeks. Wipe the lining to clean it; it is an electrical product, so never immerse it.\u003c\/p\u003e\u003ch3\u003eWho it’s for\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eStubborn MGD, or dry eye where a warm compress has been tried before and did not seem to help\u003c\/li\u003e\n\u003cli\u003ePeople who know, honestly, that they need something to prompt them through the routine\u003c\/li\u003e\n\u003cli\u003eHome and desk use, where a USB port is always within reach\u003c\/li\u003e\n\u003cli\u003eAnyone who wants both lids heated evenly rather than a mask that sits above the lash line\u003c\/li\u003e\n\u003cli\u003eNot the one for flights or the handbag — see \u003ca href=\"\/products\/lula-self-warming-eye-masks\"\u003eLula\u003c\/a\u003e for that\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eQuestions we get asked\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs it USB or microwavable?\u003c\/strong\u003e\u003cbr\u003eUSB — there is nothing to microwave and nothing to reheat. That does mean it needs a port, so it is a home or desk product rather than one for a plane. If you want something for the bag, the self-warming \u003ca href=\"\/products\/lula-self-warming-eye-masks\"\u003eLula masks\u003c\/a\u003e travel better.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow warm does it get, and for how long?\u003c\/strong\u003e\u003cbr\u003eUp to 44°C across three settings, held for a twelve-minute cycle. The figure to aim for is an eyelid temperature of at least 40°C sustained for at least 10 minutes once daily, per a 2024 evidence review in Ophthalmology and Therapy — and a mask that holds its temperature is the straightforward way to get there. Start on the lowest setting and work up. Warmer is not better — if it feels uncomfortable, turn it down.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does it beep partway through?\u003c\/strong\u003e\u003cbr\u003eAt eight and ten minutes it is telling you to blink hard, which is what expresses the softened oil out of the glands. Three beeps at twelve minutes means the cycle has finished.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs it worth it over a cheaper microwave mask?\u003c\/strong\u003e\u003cbr\u003eHonestly, not always. If your MGD is mild and you will genuinely use a \u003ca href=\"\/products\/opti-soothe-moist-heat-eye-mask\"\u003emicrowave mask\u003c\/a\u003e properly every day, that will do the job for a fraction of the price. Buy the iFlo if your MGD is stubborn, if heat has not worked for you before, or if you need the prompts to keep you honest.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use it with my contact lenses in?\u003c\/strong\u003e\u003cbr\u003eTake them out first. Twelve minutes of sustained warmth against a soft lens is uncomfortable, and you want the lids free to blink hard when it prompts you.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat if it feels too hot — and can I sleep in it?\u003c\/strong\u003e\u003cbr\u003eTurn it down or take it off; eyelid skin is the thinnest on the body. Never sleep in it.
