Why you need it: A hydrating prep step softens the surface so the next layer spreads evenly and absorbs faster.
Why you need it: This is the step that does the actual correcting — hydration alone won't change texture or tone.
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.

My skin drinks this up
This replaced a much pricier product in my routine. Faint clean scent that fades within a minute. The dry patches on my jaw have stopped flaking. The pump can be a little generous at first. Works with my retinol nights without any sting.

No irritation at all
Started with two nights a week and built up slowly. A thin gel that absorbs in seconds, which I appreciate. Texture on my cheeks looks smoother in daylight.

Nice under sunscreen
My skin runs dry and reactive, so I patch tested first. Faint clean scent that fades within a minute. My usual mid-afternoon dullness is less obvious. It took a good month before I noticed anything, so be patient.

Sensitive-skin friendly
My skin runs dry and reactive, so I patch tested first. A thin gel that absorbs in seconds, which I appreciate. Breakouts heal faster than they used to.

Happy so far
Picked this up after months of research and finally committed. Spreads easily, so a few drops cover my whole face. My usual mid-afternoon dullness is less obvious. Not a miracle, and I would not expect overnight change.

Would repurchase
I use it morning and night depending on how my skin feels. The texture is light and sinks in without any tackiness. The dry patches on my jaw have stopped flaking.

Not flashy, just works
This replaced a much pricier product in my routine. The texture is light and sinks in without any tackiness. The dry patches on my jaw have stopped flaking. I would love a fragrance-free version even so. Sits well under my usual moisturiser.

Not flashy, just works
This replaced a much pricier product in my routine. Spreads easily, so a few drops cover my whole face. Makeup goes on far more evenly now.

Good value for the size
Picked this up after months of research and finally committed. It feels cushiony going on and never pills under makeup. Breakouts heal faster than they used to. It took a good month before I noticed anything, so be patient. Pairs nicely with a simple cleanser and SPF.

Gentle and effective
Picked this up after months of research and finally committed. The texture is light and sinks in without any tackiness. Nothing dramatic, but my skin looks healthier overall. It took a good month before I noticed anything, so be patient. Sits well under my usual moisturiser.
