Is my change in skin texture from IPL or skin care routine?

I have noticed a recent change in the texture of my skin around my mouth with more open pores and a number of deep vertical lines at the side of my mouth. had an IPL hair removal treatment 8 weeks ago (7th treatment) Could the treatment have damaged my skin? For skin care I am using a Niacinimide 10% and Zinc 1% treatment in the morning before my moisturiser for some hormonal acne and a retinoid treatment at night again before moisturiser. Any advice would be really appreciated. Thanks
