This serum claims to diminish the look of lines in minutes – but does it?
Medik8 has long been a key player in anti-ageing skincare but I have to come clean and say that, while I love skincare, I'm not looking to turn back time. I want clear, glowing and fresh-looking skin, and I can live happily with expression lines and pigmentation – I truly don't care that my skin has the characteristics of ageing.
That said, Medik8's liquid peptides advanced MP serum (£79, has some mighty claims that I'm happy to put to the short-term test – especially when one of the claims is diminishment of expression lines, such as smile or frown lines, in just 10 minutes.
Like any skincare claiming to make a significant difference to texture and firmness, you're in it for the long term to reap any significant rewards and that's why the 'taster' 10 minute claim feels so enticing.
Keep reading to find out how well the serum performed during short-term testing.
How I tested
I used the serum over the course of seven days, applying it in the morning and the evening. My usual routine at night, after cleansing with either a balm or a micellar water, is an acid toner followed by a moisturiser, so, it was very simple to slot in the serum before the moisturiser. In the morning, I often don't do a specific cleanse, so I was able to add the serum before my foundation. In terms of what I was looking for, from reading the ingredient list, I was hoping the serum would give my skin some bounce and extra hydration that's much needed during the cold winter weather.
