Lucas' Papaw Ointment (sometimes available at larger Mannings stores; otherwise hope for friends or relatives Down Under to take pity on you)
A staple in every Australian girl's beauty stash, I am never without at least three tubes of this. It's an ointment made from papaya, and can be used to soothe boils, burns, itchy bites, and rashes. I use it as a lip balm and weekly face mask. All my friends in Sydney know to bring me a tube or two when they visit, so I can always have one in my bag and two or three in my drawer. I also have a huge tub by the bed so it's within easy reach for slapping all over my lips before I go to sleep.
MAC Select Moisturecover liquid concealer in NC30 (HK$165 at MAC)
I like liquid concealers because it's easy to use them to build coverage and it blends easily into the skin. If I'm ever without foundation, I can use this over a larger area, or mix it with moisturiser for a makeshift tinted moisturiser. I've tried liquid concealers from many brands, from high-end to low, but I always come back to this. It's smooth, blends beautifully, has decent staying power, and works as an under-eye concealer if need be.
L'Oreal Gentle Lip and Eye Make-up Remover (HK$85 at Watsons)
My best friend turned me on to this. I was complaining about how difficult it was to remove waterproof mascara (the only type I can use if I don't want panda eyes), and how my skin suffered from scrubbing the make-up off. And she told me to try this one. That was about eight years ago, and I haven't used another eye make-up remover since. It gets rid of every type of eye make-up, plus I can use a cotton bud dipped in it to create a perfect winged liner look.
Nars Soft Velvet Loose Powder in Desert (HK$330 at Nars)
I love Nars powder foundations, and this is always at my make-up table. I use a small, dense eyeshadow brush to pat it onto problem areas on which I've used concealer. It creates a flawless finish and doesn't look cakey. My only gripe is that the packaging is messy and you have to be careful when you use it.
ModelCo electric eyelash curler (not available in HK … sorry!)
My lashes refuses to stay curled when I use a conventional last curler. Even the Shu Uemura cult favourite won't work. I discovered this electrical one when I was visiting friends in Sydney almost 10 years back, and have always had one since. It heats up quickly, but isn't so hot it damages my lashes or the sensitive skin around my eyes, and it can create natural or dramatic-looking curls that really opens up my eyes. I've never seen this product in Hong Kong, but there are similar ones at Sasa.
