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.

Lovely texture
I use it morning and night depending on how my skin feels. Slightly rich, so I use less on humid days. The dry patches on my jaw have stopped flaking. It took a good month before I noticed anything, so be patient. Pairs nicely with a simple cleanser and SPF.

Simple and it works
Third bottle now, so that says something. Barely any scent, which is exactly what I wanted. Redness around my nose has settled down noticeably. Layers fine over my serum and under sunscreen.

My skin drinks this up
Started with two nights a week and built up slowly. A thin gel that absorbs in seconds, which I appreciate. Redness around my nose has settled down noticeably.

No irritation at all
Bought it mostly out of curiosity and kept using it. Slightly rich, so I use less on humid days. Texture on my cheeks looks smoother in daylight. Fine, not life-changing, but I keep reaching for it.

Now a routine staple
This replaced a much pricier product in my routine. Barely any scent, which is exactly what I wanted. Redness around my nose has settled down noticeably. Not a miracle, and I would not expect overnight change.

Small change, big difference
I have been using this most evenings for about six weeks. A thin gel that absorbs in seconds, which I appreciate. The dry patches on my jaw have stopped flaking.

Skin looks calmer
My skin runs dry and reactive, so I patch tested first. Melts in rather than sitting on top of the skin. My usual mid-afternoon dullness is less obvious. It took a good month before I noticed anything, so be patient. Works with my retinol nights without any sting.

Nice under sunscreen
Picked this up after months of research and finally committed. Melts in rather than sitting on top of the skin. The dry patches on my jaw have stopped flaking. Pairs nicely with a simple cleanser and SPF.
