always suffering from pimples, small rashes, and black marks

Hello and welcome to e health forum.

Oils produced by the body help keep skin healthy. But too much of a good thing can leave your face looking oily, which can result in flareups of acne and skin infections.

For your information, Stress, fatigue, weather extremes, oily skin, infrequent shampoos or skin cleaning, use of lotions that contain alcohol, skin disorders (such as acne), or obesity may increase the risk of acne.

The management of your oily skin needs proper measures to clean the skin and reduce oil production.

1. Regularly clean oily skin with warm water and a face wash that’s designed for oily skin. Just avoid the ones with harsh chemicals in them such as alcohol. This is to avoid the pores from being clogged up. Some don’t do enough to remove excess oil and dirt while other are too harsh and leave the skin too dry. This can cause the oil glands to overcompensate for the dryness by producing more oil than usual.

When washing your face, use warm water, not hot. Extremes of temperature can also irritate skin.

Be sure not to wash your face too many times a day. This will also cause it to dry out and cause the oil glands to overcompensate. For most people once in the morning and once as night is enough however on some days one extra wash in-between could help out without causing any dryness.

2. If a basic facial cleanser doesn’t do the trick, try a product that includes an acid such as benzoyl peroxide, salicylic acid, glycolic acid, or beta-hydroxy acid. Acids help cut oiliness.

3. Another option is medicated pads with salicylic acid, glycolic acid, or other oil-cutting acid ingredients. They help to freshen up your skin and remove excess oil.

4. Cosmetic blotting papers can also be used for removing oil because they don’t dry out your skin. Apply to oily areas, such as forehead, nose, and chin. Don’t scrub your skin with the sheet of blotting paper. Instead, simply press it against the oily area long enough to allow it to absorb oil, usually 15 to 20 seconds.

In addition, using a good moisturizer and a oil free sunscreen will also help to improve the skin health and condition.

In case the above measures are not helping, you may consult with a dermatologist who can advice you measures like chemical peels to reduce oiliness and improve the overall look of your skin.

In addition, treatment of acne with prescription medications like tretinoin, adapalene, or tazarotene can also help you to reduce acne formation.

I hope this helps.
