Thank-you for your question, Majida. Your plan of action needs to be 3-fold:
1) You need to try and refine the pores by means of a chemical exfoliation. I would highly recommend something like a Lamelle Beta Peel or an Obagi Radiance Peel (Suitable for all skin types). 2) You need to ensure maximum skin hydration, as pores often look their worst when the skin is not properly hydrated. For this, I would recommend something like Lamelle Corrective HA Plus serum. 3) Lastly, I would recommend daily on-going protection as sun damage also worsens pores and their appearance. For this, I would recommend Heliocare 360.
