The actress and comedian talks to Andrea Smith about her favourite purchases
I get a good colour in summer, but go really pale in winter and it genuinely doesn't suit me as people ask me if I'm ill. As well as making me look a bit better, I often have to be tanned in the middle of winter to do a show or programme, so I've road-tested every fake tan on the market. I find TanOrganic Dry Oil (TanOrganic.com, €24.99) the best of all, as it moisturises your skin at the same time as bronzing it and I think it's fabulous.
My sister Grainne introduced me to doTERRA essential oils (from €12, mydoterra.com/grainneokane). They're great and when my kids are hyper, I rub some lavender oil behind their ears and they're asleep in 15 minutes.
My mother Lilian trained as a beautician after she reared us, and was one of the first people to bring Dr Hauschka into the country. She has hardly a line on her face, so I'm throwing money at mine by using Dr Hauschka Rose Day Cream (TheHealthStore.ie, €26.95) and hoping to Christ I can turn back time.
I'm a great lighter and lover of candles, particularly fragranced ones, as I'm kind of addicted to scent. I fell in love with the magnificent La Bougie Lichen & Winter Jasmine candles (€19.95 and €29.95) from Cork when I was given a gift of one. I love candles in the evening, as they're great for ambience and calming things down. And if my house is a mess, I light a few candles and everything looks instantly better - I'm all about the smoke and mirrors.
I'm discovered Java Republic Peppermint Tea (€6.49, JavaRepublic.com) on an Aer Lingus flight. Once you've tried its silk bag, you won't look back and I buy it online now. It's so good that I'm dying to try their coffee next, and if it's as good as the tea, I'm going to switch. I love peppermint tea as it's much nicer than taking anything chemical for settling your stomach. I've become such an aul one!
I could probably die happy with a cheeseboard and a glass of French red wine - that's my idea of a perfect dinner. My in-laws introduced me to Gubbeen Cheese (€8.65 for 450g, SheridansCheesemongers.com) and it's such a treat.
I can't seem to be able to live without my white leather Converse Chuck Taylor All Star trainer boots (Arnotts, €80). I first saw them on another woman, and went out and bought them as they're a thing of beauty. They're not just for summer, as I wear them with black skinny jeans and cashmere socks in winter and feel the white lifts me. With commuting to Dublin from London so often, they're perfect for getting through the airport without having to take them off at security.
Deirdre is not the only one who needs a bit of help on the old bronzing front. If you're at risk of turning whiter than a Hallowe'en ghost this winter, the new matte and shimmer Cocoa Brown Bronzing Gels (€6.99 nationwide) will give you a fab sun-kissed look while you're shivering at the Luas stop.
With colder days approaching, it's time to replace the ice-cold soft drinks with a nice warming cup of herbal tea. Diplomat peppermint infusions from Aldi are a snip at €1.25 for 40, and they'll soothe your system when you've overloaded it with takeaway and wine while watching The X Factor.
Like Deirdre, most of us are partial to lighting an ol' candle of a frosty evening, particularly if romance is potentially afoot. Everyone looks far less repulsive by the forgiving glow of candlelight, so to help your love life, IKEA has candles in every scent and colour imaginable, like this Sinnlig lilac blossom candle for only €3.25.
God we hate when we move into the 'mature skin' category, but sometimes we have to face harsh reality. So while we're still raging about having to buy Olay anti-wrinkle cream for mature skin, at least the €7.24 price from Boots doesn't add insult to injury.
Deirdre stars in 'Are You There Garth, It's Me Margaret' at the Gaiety Theatre from October 13-25, www.ticketmaster.ie
