Niacinamide is a form of vitamin B3 and antioxidants that helps reduce the appearance of pores, uneven tone, fine lines, and wrinkles for a flawless complexion! It also promotes natural ceramide production and a healthy skin barrier.
I've also added chamomile which helps with redness, hyperpigmentation, acne, eczema, & soothes sensitive skin.
And of course aloe vera since it also reduces inflammation, redness & works as an astringent that reduces the size of pores all while moisturizing your skin! 
Apply your water based serum daily after cleansing and before heavier or oil-based serums, moisturiser and sunscreen.
