During festivals like Navratri, there are bright lights. So, for your night make-up, you will need bright colours, otherwise your face will look pale.  First, cleanse the skin and apply a liquid moisturizer. For oily skin, apply an astringent lotion with cotton wool.  Wait for a few minutes. Then, cover blemishes with a concealer, before applying foundation. Or, use a lighter colour foundation on dark blemishes and then apply normal foundation on the entire face. If you wish to cover a pimple or spot, it should be done before applying foundation or powder. Concealing sticks are available for this. Using a thin brush, paint over the spot with a little concealer, or lighter shade of foundation.  Then, apply a little powder. Dot foundation on the face and blend with a damp sponge or with finger tips. Don’t forget the neck. Apply loose powder, or try compact powder to set the foundation.  Use foundation with beige tones, rather than pink. I feel beige suits Indian skin colour better.
