Mistake #1 is not moisturizing oily skin
Regardless of your skin type, it’s imperative that you moisturize daily and apply a heavier cream at night. It's important for oily skin to get moisture so your skin doesn't overcompensate for the loss of hydration with more oil. The right moisturizer adds water to the skin, not oil.
Mistake #2 is not applying skin care products in the correct order
One of the keys to maximizing the benefits of anti aging skin care products is to apply products with a thinner consistency before the thicker, creamier ones. For instance, apply serums before creams. Products with heavier consistencies can block lighter weight ones from penetrating the skin and doing their job.
Mistake #3 is drying out your skin
People with acne or the occasional pimple think they need to dry out their skin. When you choose products that are too harsh you can cause further irritation than the breakout itself. You should use a product that soothes while it targets your skin concern and always finish with a hydrating moisturizer.
Mistake #4 is over exfoliating your skin
The more you scrub, the more damage you’re likely causing your skin. It might be tempting to try to scrub away blemishes, acne scars, age spots or other skin imperfections, but the truth is that the more you scrub, the more damage you’re likely causing your skin. While some exfoliation can be beneficial, as this removes the outer layer of dead skin, dirt and other debris from your skin, overdoing it may cause damage and irritation. Instead, assess your skin type and condition, and exfoliate accordingly.
Mistake #5 is wear sunscreen whenever you are in the sun.
The biggest anti-aging tip any dermatologist will give you is a preventative one: Protect yourself from the sun. But people tend to think if they aren’t going to be staying out in the sun, they don’t need to apply it. The thing about your skin is it doesn’t care how long you are in the sun - any exposure, no matter the length of time, is still damage. Five minutes here, 10 minutes there—it all adds up.
