Vit C Recommendations [Skin Concerns][Acne]

Hey! I'm looking to add a Vit C serum to my morning routine. I have some lingering hyperpigmentation from a severe hormonal acne flare up that I experienced about 9 months ago. I also have mild sun damage on my on the sides of my cheeks-derm said it may be a form of mild melasma.

Dry/Acne-prone skin AM: PC Pore Normalizing Cleanser, PC 2.5% BP, Trader Joe's Antioxidant moisturizer, Neutrogena break-out free sunscreen SPF 55, Makeup Forever oil-free liquid foundation

PM: Garnier micellar water pink cap as makeup remover, PC Pore Normalizing Cleanser, PC 2% Clear BHA, PC 2.5% BP, Trader Joe's Antioxidant moisturizer

I am also on a higher androgen BC (Levora), I'm too scared to switch as my skin seems to be responding alright, and I'm currently tapering off if Doxy by taking 50 mg of 2x a day.

Thanks!
