The Skin Nerd Shares Her Top Tips For Teenage Skin

Here's everything you need to know in the world of skincare.

Skincare can be confusing at the best of times, we get it. Particularly when there’s no ‘one size fits all’ when it comes to skincare, and the fact that our skin is constantly changing.

Where do you start? Do you double cleanse twice a day? Is SPF necessary every single day? Spoiler alert, yes it is. There are so many questions.

So, we caught up with the skincare expert that is Jennifer Rock, aka The Skin Nerd, to hear her top tips for nourishing, protecting and tackling any concerns for teenage skin. Check ’em all out below.

Wash your hands before applying skincare

“We’ve been talking a lot about the importance of handwashing, but it’s also key when it comes to applying your skincare. Make sure you wash your hands before you cleanse or apply any product to your skin to make sure you’re not spreading any bacteria into your precious pores. Handily, you’re probably already in front of your sink when you’re using skincare!

Cleanse your skin twice a day

It’ll take you 90 seconds, morning and evening. Double cleansing is the process by which you pre-cleanse your skin with a pre-cleansing tool or balm, and then follow up with the gentle cleanser of your choice. It’s surprising what a difference double cleansing your skin morning and evening can actually make to your skin. It’s one of the best skin habits you can get into – it removes excess oil, SPF, makeup, or any other product from your skin!

I suggest pre-cleansing with a tool like the Cleanse Off Mitt (a microfibre makeup and pre-cleansing tool of my own creation). Simply run it under warm water for a few moments, squeeze it out, and swipe it in small circles from the centre of your face outwards. Afterwards, reach for your gentle daily cleanser (I’d recommend Skingredients PreProbiotic Cleanse, or Galinee’s La Culture Foaming Facial Cleanser). Pump out a coin sized amount, apply to skin (from the nipples up – cheeky, I know, but that’s what a good cleanse entails), and massage it into your skin for 60 full seconds before cleansing it away with your Cleanse Off Mitt.

Feed the skin from within

As well as keeping hydrated and drinking plenty of water, eating water-rich foods is another great way to keep that skin hydrated, so you could snack on grapes or oranges and similar foods, all with the excuse of skin health. Eating a healthy, balanced diet contributes to good skin health, too – such as fatty acid-rich foods like oily fish (mackerel is a great option), nuts, seeds, and even seaweed, too! These can be beneficial when it comes to conditions like acne and eczema as they can help to bring down inflammation in the skin.

SPF every day!

SPF isn’t just the sticky sun cream that you might remember being slathered onto your skin at the beach – it’s much more sophisticated now. There are plenty of options for all skin types, so you don’t need to look like Casper the Friendly Ghost, and plenty of options which won’t break you out and are totally unnoticeable on the skin, too. It’s one of the best things you can do to help your skin avoid premature ageing, and protect it against serious illnesses like skin cancer, which is the most common cancer in Ireland, according to the Irish Skin Foundation.

Bin the wipes and remove your makeup before bed!

Makeup wipes seem like an easy option but the fact is that they’re not very skin-friendly. They don’t effectively remove product from your skin, they can sensitise your skin over time, and they aren’t that eco-friendly, either. The Cleanse Off Mitt can effectively remove product from skin, it’s washable, reusable, and suitable for all skin types, too!
Your skin does important work overnight, and if you don’t remove makeup, then your makeup can get in the way of these skin renewal, and can cause breakouts, too.

Clean your makeup brushes

Did you know that you’re meant to clean your brushes after every use? It makes sense – our brushes are getting up close and personal with our skin, and they can be a breeding ground for bacteria which we then transfer directly to our skin. If you don’t have time to deep clean your brushes after use (I get it), then you could use something like Ella & Jo Squeaky Clean Brush Cleanser – simply spray it on post-use, swirl your brush around on clean tissue paper, leave it to dry for two minutes, and you’re good to go until your next deep clean.

Tackle breakouts from the source

If breakouts are getting you down, use products which are tailored to spot-prone hoomans. For hoomans over the age of 16, Skingredients Sally Cleanse is suitable. Sally Cleanse contains 2% salicylic acid, which is an exfoliating acid which cuts through oil to dissolve blockages in the pore. It’s also a spot zapper! You can apply Sally Cleanse directly to the spot for 3 minutes before cleansing away. And remember, you should only use Sally Cleanse up to three times a week in the PM to avoid over-exfoliation of your skin.

If your breakouts are truly getting you down, speak to a parent or guardian about seeing a doctor or specialist – medication can sometimes be required to stop acne in its tracks.
