[Routine Help] How do I incorporate Pixi Glow Tonic and other questions. 27/F Pale ginger with light freckles.

I bought a sample bottle of Glow Tonic and have been using it for the last 3 evenings. Is using PGT every evening too much for someone just getting into AHA? I have dry/normal skin and can be sensitive to fragrances. My main concern is the small blackheads on either side of my nose and flakiness in the creases of my nose which is why I thought an AHA would be useful. I think I might be experiencing purging due to the increased texture of the blackheads, do I need to be concerned about that? Also, how do I incorporate retinol? Other than the blackheads/texture I'm concerned about aging.

My current routine is: PM Coconut oil if I am wearing eye makeup

Micellar Water if I am wearing makeup

Cetaphil Daily Facial Cleanser with a manual silicone "brush"

Pixi Glow Tonic (replaced Thayers Rose Petal Witch Hazel Mist)

TruSkin Naturals Vitamin C Serum (not sure if this is actually doing anything)

Shiseado White Lucent Eye Cream (I like the moisturizing aspect of this and the thickness but I need to replace it with something less expensive and it doesn't do anything for dark circles as it promises. Also might be causing mild milia.)

Clinique Dramatically Different Moisturizer+ (Been using this since I was a teenager but when I run out I might try using CeraVe Moisturizing Cream which I use on my hands every night)

AM Water

Thayers Rose Petal Witch Hazel Mist

CeraVe AM Facial Moisturizing Lotion SPF 30 (this can feel a little heavy sometimes and has a strong sunblock smell but it's the only sunscreen I've found that doesn't burn under my eyes)

Any suggestions, critiques, or answers would be greatly appreciated. Thank you!
