Saadia, pores usually open-up and become larger/visible due to hot water and steaming..which is a step in every facial.. and if u suffer from large pores u can eliminate this step! Tomato's tighten pores.. and so does "alum"
Zara, discoloration happens because of either the great amounts of sulphur used in depilatory creams and the friction and pulling/tugging due to waxing as well. Keep the area dry, and apply moisturiser stay away from fragranced products.
Somehow, it really depends on what suits u're skin.. some people swear by Oil of Olay, some by Nivea and Neutrogena...I use Baby Johnson's as a cleanser, L'Oreal's toner and The Body Shop's Vitamin E face cream..(always massage u're face in upwards and outwards strokes)
Nancy, glycerine doesn't work for all skins. Some breakout because of glycerine too.. but rosewater tightens pores and works well as an astringent it also balances the pH level of u're skin.
