There are definitely treatments that are effective for both hyperpigmentation and enlarged pores . However, first and foremost, it will depend on the cause and kind of hyperpigmentation that you are having, the cause of your enlarged pores and presence of any other associated conditions like acne, as well as the extent of your hyperpigmentation.
By and large, topical therapy, injectables, lasers and radiofrequency micro-needling will be able to treat hyperpigmentation and improve skin texture e.g. enlarged pores to a certain extent.
Topical therapy will include creams that contain retinoids which will increase cell turnover, stimulate collagen and inhibiting tyrosinase activity, hence improving hyperpigmentation and reducing debris buildup in pores, resulting in improved skin texture. Chemical peels will also help to increase epidermal turnover and hence improve hyperpigmentation and skin texture.
Injectables like Rejuran(PDRN) have been shown to help with scars, pores and pigmentation through the anti-inflammatory, regenerative and reparative properties of polynucleotides.
Lasers like Picosecond lasers and Q switch Nd:YAG lasers are effective in helping to clear pigments and improve skin texture through photoacoustic and photothermal effects respectively. In my practice, I like to use the newer PicoSure laser for both treatment of pigmentation and skin texture as it has a shorter downtime and lower risks of post-inflammatory hyperpigmentation.
Lastly, pulsed radiofrequency microneedling treatments e.g. Sylfirm helps with restoration of the skin's basement membrane and ablation of small vascular lesions and abnormalities which in turn improves pigmentary conditions like melasma and can also improve skin texture.
