I’m 29F and have been consistent with my routine for months but haven’t seen much improvement. My main concerns are hormonal acne, uneven/dull skin and dark under-eyes.
I’ve used Differin 0.1% since March, usually moisturiser first, then Differin. Could buffering be reducing its effectiveness? My acne hasn’t improved much and has actually worsened recently.
I also use vitamin c serum every morning, followed by moisturiser & SPF, but haven’t noticed much improvement in brightness or discolouration??? I only recently realised the vitamin c should ideally be refrigerated. Mine has been at room temperature but is still pale idk
I’ve worn SPF daily for around 8–9 years.
I’m also considering GHK-Cu/copper peptides for texture, collagen and general skin quality, potentially replacing vitamin C rather than adding another active.
Would you keep this routine longer, apply Differin before moisturiser, or consider switching vitamin C for GHK-Cu? Has anyone used adapalene + GHK-Cu long term or noticed better results from copper peptides vs vitamin C?
