I want to buy this to combat my skin texture but I'm worried the 10% of niacinamide plus zinc will be too aggressive for my face. I already use a niacinamide toner but I want to buy this as the toner just isn't strong enough. Any thoughts? Maybe there's some stronger niacinamide toners?

Too strong for sensitive skin?

It leaves a pinkish-red tint on your skin immediately after applying, but it does go away pretty fast.

I love this serum! I have quite sensitive skin, and I use this every morning and night to combat redness and irritation and it works amazingly! My skin feels so much smoother and more hydrated, and it absorbs into the skin very fast and leaves it so glowy! My skin is way less red and has been getting irritated much less since I've started using this.
The pictures are before using the serum and then 15 minutes after and as you can see my skin is way glowier and it felt much softer.

Right after applying this product my skin feels very oily and unpleasant for about 15 minutes, but after that it absorbs and feels much nicer. However, it is quite a heavy cream so you will still feel it on your face throughout the day. Also, I like to apply it in the mornings as a moisturiser, and I usually need to reapply in my dry spots - the corners of my nose etc, as it just dries out by the afternoon.

This cream is so incredibly moisturising and calms my skin so fast! When my skin is red, dry, or irritated, I apply the cream at night and next morning it's so hydrated and smooth. It soothes my skin really fast and leaves it feeling so silky even after washing the cream off. It's slightly thick, but absorbs into the skin really easily. 
The photos are my skin before and after the cream (but it's opposite cheeks which is why the moles are different). 

Not a very strong cleanser, it says it removes makeup but its not that effective. If you wear makeup during the day I'd opt for a different product.

It leave my face moisturised and not stripped after cleansing. Also isn't too harsh, so if you have sensitive skin you don't have to worry. I also love the texture, once you warm it up in your hands it turns into an oil that glides onto your skin.

It's very watery, which means as you're squeezing out the recommended 'pea sized amount' the serum just spills all over your hand. Immediately after applying it's very tacky and shiny on the face (but that does completely go away after a few minutes). It doesn't make my skin feel hydrated or plumped.

It makes my skin feel super smooth and look soooo glowy.
