In addition, the benefits offered by these products are also very diverse. Well, but there is at least one reason why we shouldn't be easily tempted to try skin care. Because, there are some skin care ingredients that should not be used together, you know. Chestnut Hill, Massachusetts, Brooke Sikora, MD, as reported by Everyday Health. Vitamin A derivatives, such as retinol and retinoids, and Alpha Hydroxy Acid (AHA), such as glycolic acid, are dermatologists' choice for anti-aging. This is because these ingredients can accelerate skin cell turnover and increase collagen production so that the skin looks shiny and free from fine lines. However, in this case, more product does not mean better.

When we experience skin irritation, we tend to reduce the frequency of using the product, which in turn can reduce the effectiveness of using skin care. But, that doesn't mean you have to get rid of one if you have both products. Just use the product on different days. For example, products with AHAs on Monday and products with retinoids on Tuesdays, and so on. However, there is one exception. The two ingredients may be combined in one product if it has been specifically tested through clinical trials. Also read: Using Skin Care of Different Brands Can Be Dangerous, What's the Reason? Although known as anti-aging, retinoids are also effective for treating acne because they can exfoliate the skin and prevent clogging of pores. However, think twice if you want to combine products containing retinoids with products containing benzoyl peroxide. Previous research has found that newer formulations of the retinoid tretinoin can remain stable when combined with benzoyl peroxide. Some products are also specially formulated by combining the two ingredients. However, as an alternative, you can use a product with benzoyl peroxide in the morning and a product with retinol at night.

The solution, you can still use the two products but at different times.

Sikora explains, vitamin C is a difficult ingredient to formulate because it works most effectively in an acidic pH environment. While retinol works in an environment with a higher or more alkaline pH. If used together, both will not work optimally. The solution, you can still use the two products but at different times. Retinol is best used at night because it makes the skin more sensitive and can increase the risk of sun damage. While vitamin C works best during the day because it is an antioxidant that protects the skin from attacks during the day, such as pollution and ultraviolet rays. Many people have skin aging problems, but also acne problems. To combat signs of aging, such as the appearance of fine lines and wrinkles, you may use products containing retinoids. Meanwhile, to deal with acne problems, you may also use products containing salicylic acid, beta hydroxy acid (BHA) which stimulates skin cell turnover, thus keeping pores clean. However, each ingredient can make the skin dry. So, combining products with these two ingredients must be done carefully.

Are you planning to buy an automatic car? Or planning to ride it in the near future? Maybe you already know that the way to drive an automatic car is different from the usual car, which shifts the gears manually.

But if you are not used to having to be careful, you might get confused between the brake pedal and the pedal or the wrong way to use the automatic car gear. Not infrequently heard of accidents because they are not familiar with how to shift gears automatic cars that are not familiar. Therefore you must know some important things in how to drive an automatic car below. As a beginner you need to be careful so that the lever is always in the correct position. First before starting the engine, the lever position must be in the P position or in the N position. Do not position the lever in reverse or R, these positions are used to reverse. If the lever is in the R position, the car will not start when it is started.

When you enter the key, do not immediately start the engine. You should wait for the needle to spin until the indicator is active or lit which indicates the electricity is ready. Some types of automatic cars provide an indicator in the form of sound when the car is really ready to be started. When first starting, it is recommended to step on and hold the brake pedal for safety reasons because you are afraid that the car will suddenly accelerate forward. Some automatic cars have an automatic procedure that keeps the engine running if you don't press the brake pedal, although some don't. When the engine is on and you want to start moving, the first step that needs to be done is to change the gear position of your automatic car which was originally in position P or N, to position R to go backwards or D to go forward. It is important to depress the brake pedal at the same time as moving the lever in gear. This method can prevent damage to the machine. The transmission lever aka gear or automatic car gear is an important component that affects the speed of the car.

In general, whether it's Agya automatic car gear, Mobilio automatic car gear or others have DSLPR and N automatic car gears. Well, you need to understand each function of the automatic car gear.

That's roughly how to drive an automatic transmission car alias matic. It's actually simpler and more practical than the manual one, but if you're not familiar, it takes time to adjust. Especially from the transmission side which uses different codes. Not only numbers that indicate the order of teeth as in manual cars, but the shape of the teeth of automatic cars also uses a code in the form of letters to indicate their respective functions. What are the codes and their functions? Let's move on to the next discussion. As already mentioned a little above, in general, the transmission lever is marked with letters and numbers, namely P, R, N, D, 2, and L. This is standardly applied to various brands, be it in Xpander automatic car gears, gear shifters Honda Jazz automatic car, Ayla automatic car gear and even Avanza automatic car gear.

But that does not mean its function is the same as the parking brake.

Therefore, in order to drive an automatic car well, you need to know what the letters and numbers mean and what their functions are. The letter P on automatic car gear stands for Parking alias parking. When you set the gear in this P position, the transmission will be locked and the car engine cannot move. But that does not mean its function is the same as the parking brake. Unlike the parking brake, when the transmission lever is in the P position, the car's wheels can actually move, but the transmission is locked and the engine cannot move. That's why the P position is used when the car is stopped for a long time or in parking conditions. The R symbol in automatic car gear stands for reverse.

As the name suggests, when the transmission lever is moved to the R position, it makes the automatic car you drive move backwards or backwards. Next is the code N which stands for neutral. In the N position, the car engine will be in neutral but not locked as in the P position earlier. So the car can still move forward or backward when pushed. In addition, the N transmission can also be used when the car needs to stop for a while, such as when conditions are jammed. You can use D or Drive to advance on flat and normal road terrain, aka not on incline or potholes. You just have to adjust the gas and brakes, shift gear problems, the Electronic Control Unit (ECU) embedded in automatic cars will do it for you automatically according to engine speed and car speed. Usually, code 2 on automatic car transmissions is located under D, while 3 is next to the D code. Position 3 or can be interpreted as D3 on automatic cars is used to instruct the engine to limit the maximum gearshift to 3rd gear only. While the position in 2 or automatic car gear S (Second) automatic car gear for an incline that is not too steep. Apart from going uphill, you can also use it when you need the engine brake when going downhill. When the incline has been successfully passed, do not forget to move the car transmission from the L position. This is important so that the engine and transmission do not receive heavy pressure so as not to damage the components inside. You can also use the L position as an engine brake, especially when you go on a fairly sharp derivative.
