The key to clearing up your skin from blemishes/oiliness is to understand the anatomy & physiology of the skin.. the skin on our face is the most sensitive skin amongst other parts of the body that's why we need to give meticulous care to our facial skin.. I recommend you to wash your face 2-3 times a day only. The rationale for this is that, excessive washing of face with anti-acne/anti-oil products will strip off the natural moisture of our skin.. when the natural moisture is gone, our skin sends a signal to the brain which activates the oil glands to release oil to keep it hydrated.. that's why when you overwash, your skin will become more oily.. should you need to wash it often, then use plain water only and pat dry.
the only thing that helped me diminish oiliness and acne are:
1. I wash my face thrice a day. I only use cleansers before school and before I sleep. I wash my face with water only in the middle of the day.
2. I use skin care products that are same brand (Loreal PureZone skin care line is the only line that helped me diminish oiliness so far)
3. I don't use face powders
4. When my face is oily, I use oil absorbing sheets or I wash my face with plain water and pat dry.
5. I use oil-free, non comedogenic moisturizer everytime I wash my face.
6. I only use alcohol free toner (from Loreal PureZone)
7. I treat my face with clay mask twice a week to tighten pores.
8. I drink at least 8 glasses of water to keep me and my skin hydrated.
9. I use lemon extract or tomatoes and leave it on my face for awhile. I've read somewhere that its extracts cause very mild irritation which causes ur skin to shrink, thus, helps lessen oiliness.
10. I go to the dermatologist once a month for glycopeel/spanish peel treatment.
11. I dab Mario Badescu's pimple gel when occassional breakouts appear. Its so amazing!
MY ADVICE for you is to be a responsible and meticulous consumer. Check the label when you're buying skin care products. Don't be fooled by marketing schemes and false advertising. If they are saying something that are too good to be true, then don't buy it. Another thing is not to use too many products or change it often (that is, if its not causing allergy) because our skin takes time to adjust to a new product. Acne or pimples cannot be removed or be gone in an instant. It takes time to actually get rid all of them.Patience is another key to get rid of acne. I got rid of my acne in 8 months religious treatment. If you have already found the right skin care products to use, then stick to it. Look for products that contains one of the following: salicylic acid, witch hazel, tea tree oil, glycolic acid, AHA/BHA. These ingredients are well known for treating oiliness and acne. Hope I've given you ideas on what to do. But it is always recommended to ask your dermatologist for proper evaluation and treatment.
