Thanks to certain culprits that shall remain nameless (cough, air conditioning and English weather, cough) it's completely normal for your skin to be feeling a little thirsty at this time of year.
If your moisturiser isn't quite delivering the hydration you deserve, may we suggest you try adding a clever ingredient into your skin routine.
An ingredient that smugly holds up to 1000 times its weight in water and keeps that on your skin. Show off.
Say hey to hyaluronic acid, the beauty staple that the skinfluencer lot can't get enough of.
But don't be put off by the mention of 'acid' .
Confusingly, hyaluronic acid does the opposite job to your exfoliating acids and is named after the enzyme that synthesises HA, called 'hyaluronic acid synthase'.
When should you use hyaluronic acid?
You should use hyaluronic acid on your face and neck where you would normally use a serum. For best results, apply AM and PM, after cleansing/exfoliating and before you add moisturiser and SPF.
Cool, so now you're acquainted with the wondrous HA, here are the very best infused serums to add to your bathroom shelf...
