1. What are the key make-up trends for spring/summer 2018/19?
ST: "Firstly and most importantly, skin is going to be in. It’s so beautiful when you can see your skin through the makeup. That's why I love the Marc Jacobs Shameless foundation ($70; at sephora.com.au). It’s designed to mimic your skin’s texture and it’s self-setting so you don't need to finish it with a tonne of powder.
"On the red carpet, we’re seeing bold statements and more colour, it’s very empowering and I think it says a lot about where we are here in 2018."
2. Is there a modern way to wear colour?
ST: "It's all about creating eyes with sheen and I think glitter will be big again this season. Marc Jacobs has just launched a new eyeshadow with a gel formula, it feels like a cream when you're putting it on but its natural powder eyeshadow. They're called the O!mega Shadow ($42 each; at sephora.com.au) and they come in individual colours, my favourite is a nude tan shade called, ‘the big O.’ You can use every single day to create definition around the eye socket and it's smooth and easy to blend."
3. What is it like working with Lady Gaga?
ST: "I have worked as her personal make-up artist for five years and part of her team for ten. I‘ve learned so much doing her make-up because what I do with her so is different to everyone else, as a performer she has so many mediums of art.
"For the red carpet, I always want to be able to see her skin, so I talk with her facialist about how we are going to prep her skin for that day. I really trust Marc Jacobs Shameless foundation, because it doesn’t end up getting really shiny and it looks natural. Marc Jacobs highighliner glam glitter gel eye crayon, ($36; at sephora.com.au) is another go-to product that I have in every colour. You can use it as a sharp eyeliner or buff it out as an eyeshadow."
4. Are there any pharmacy beauty products that people might be surprised to find in your kit?
ST: "One of my favourite moisturisers in the whole world is Cetaphil ($20; at pricleline.com.au). It just works on everybody it's really good under make-up.
"For taking it off I really like Neutrogena Makeup Remover Cleansing Towelettes ($8; at priceline.com.au) and I also really like Ole Henriksen Truth on the Glow Cleansing Cloths ($22; at sephora.com.au) they contain Vitamin C and they smell amazing.
5. What is one of the most common make-up mistakes that you notice on women and how do we correct it?
ST: "One thing that irritates me is make-up that is too heavy during the day, highlighter in particular. It's so bright that it could direct air traffic. Instagram makes women feel like they have to wear more make-up or they have to look so perfect that every pore is covered and that's something that I think is a huge mistake, I don't think that most people find that sexy or powerful."
