Tips
Sometimes we become too much conscious about our skin care and do repetitive cleansing and scrubbing.This results in blemishes.So instead of too much of cleaning,it is better to use a gentle and a mild cleanser a day.

Day makeup should always be simple,instead of heavy makeup.

You can choose an acne pad,to remove excessive oil and dirt.

If skin is blemished, cleanse and moisturise the dry areas.

Do not ever start on experimenting with 4-5 products thinking that some magic will happen over night.

Stressing your face will only make your skin prone to acne,as the oil glands will become more active and send more oil to the surface.

Use broad spectrum UVB/UVA chemical sunscreen with SPF 30 to protect your skin.Do not forget to apply the sunscreen after every 2-3 hrs as the sunscreen effects for a limited period of time.
