First thing to note is that – like pretty much all retinol formulas – this one is best used at night time as it can increase skin’s photosensitivity. Using just a pea-sized blob each evening, I slid this product into my existing PM routine, omitting all other potential irritants such as exfoliating acids, just to give my skin the best shot at getting used to it.

With a light, creamy texture not too dissimilar to the brand’s Priming Moisturizer, £18, it’s a dream to blend. To apply, I simply pat mine into my cheeks and forehead, dodging the delicate skin around the eyes but also avoiding my lips and chin, simply because this is where my dermatitis usually strikes. On day one, I braced myself for a bit of an initial itch but felt only a mere tingle which, by day five, had pretty much subsided.
