The daily exfoliater - is that a scrub type thing with little bits in it? It might be too harsh.
Hyaluronic acid is a hydrating thing - it's not acid I the sense of irritating your skin and occurs in the body naturally. It attracts and holds water and should plump up your skin. It's in lots of creams and serums.
Glycolic acid is a chemical exfoliant. It dissolves dead skin cells revealing newer ones underneath. Retinol encourages your skin to renew itself. It's a form of Vitamin A. Both of these can be drying.
Lactic acid is a more gentle chemical exfoliant. There's also salicylic acid which is more for clearing blocked pores.
Oily skin can be a sign of being dehydrated as skin tries to help itself by producing more sebum.
You might be drying out your skin too much with the Dermalogica and the cleanser. I use La Roche Posay Toleraine cleanser for sensitive skin. I get about 4 months out of the big 400ml bottle which is about €20. Only use warm water, never hot. I have heard CeraVe hydrating cleanser is good too.
La Roche-posay Toleraine nuit moisturiser might be good for the rosacea. Or the cicaplast baume.
You could do an oil cleanse first and then the LRP afterwards to take off the oil.
I don't know what the double wear serum is you mentioned. Lots of serums are rubbish though compared to specifically buying a retinol or acid or Vit C serum.
Also you should wear SPF every day of at least 30, and this will be compulsory if you are going to try acid exfoliants or retinol.
