No ah I just mix everything (3 serum) with toner in the evening .
I have combination skin and m currently using
1) the Arbutin - for whitening ( super nice )
2) B5 in HA - for hydration ( thick texture I don't like , need to dilute with toner)
3) EUK - anti aging serum
I also use their eye and hair serum occasionally
Been using it for a month , happy with results so far . Pores tighten , even skin tone (and brighter ) , smooth skin and less oil secretion . But I switch my basic skincare to Avene at the same time so maybe it's the action from both , not just the Ordinary
Another must have item is the spreadable base . It's amazing . I share it with 4 frens and they all love it (emoji)
I like the gentle foaming cleanser (2 dots) . It cleans the oil and dirts in pores (like melting them) and not leaving skin dry like the cleansing gel (3 dots)
I bought from salxxsa beauty (cheap) or from my facial salon (more expensive )
