Why you need it: Actives can't absorb through leftover oil, sweat and product build-up — cleansing first is what makes the rest work.
Why you need it: A hydrating prep step softens the surface so the next layer spreads evenly and absorbs faster.
Why you need it: Without a moisturiser on top, the water and actives you just applied evaporate and the skin can feel tight or irritated.

Slow but steady results
I have been using this most evenings for about six weeks. Slightly rich, so I use less on humid days. The dry patches on my jaw have stopped flaking. The pump can be a little generous at first.

Not flashy, just works
Started with two nights a week and built up slowly. Spreads easily, so a few drops cover my whole face. My usual mid-afternoon dullness is less obvious.

Better than I expected
My skin runs dry and reactive, so I patch tested first. Spreads easily, so a few drops cover my whole face. Nothing dramatic, but my skin looks healthier overall. Layers fine over my serum and under sunscreen.

Gentle and effective
I have been using this most evenings for about six weeks. The texture is light and sinks in without any tackiness. My skin feels comfortable all day instead of tight. Works with my retinol nights without any sting.

Simple and it works
Picked this up after months of research and finally committed. Faint clean scent that fades within a minute. My skin feels comfortable all day instead of tight. Not a miracle, and I would not expect overnight change. Sits well under my usual moisturiser.

Pleasant to use daily
This replaced a much pricier product in my routine. Barely any scent, which is exactly what I wanted. Breakouts heal faster than they used to. I would love a fragrance-free version even so. Fits into a very basic three-step routine.

Gentle and effective
Picked this up after months of research and finally committed. A thin gel that absorbs in seconds, which I appreciate. Redness around my nose has settled down noticeably. I wish the bottle were bigger for the price.

Subtle glow over time

Better than I expected
Third bottle now, so that says something. The texture is light and sinks in without any tackiness. Texture on my cheeks looks smoother in daylight. Fine, not life-changing, but I keep reaching for it.

Gentle and effective
I use it morning and night depending on how my skin feels. Barely any scent, which is exactly what I wanted. My skin feels comfortable all day instead of tight.
