Are you looking for skincare advice? Professional dermatologists share their top maintenance tips, the rules they’ve learned throughout their careers and recommend to their patients. The following are 21 correct skin care methods and techniques recommended and shared by dermatologists: 1. Understand the skin cycle Studies have found that the average person’s skin renewal cycle is one month. If oily skin wants to be more frequent, it can be done once every two weeks, and dry skin is recommended to be once every two months. Everyone goes through periods when their skin feels overwhelmed, but masks can quickly balance skin: A mud mask reduces oiliness, while a gel calms redness. 2. Moisturizing at night is more important If you wake up with dry skin, it’s time to change up your nighttime skincare routine, not your morning routine. Prevention is better than cure, and it’s easier to moisturize at night than to fix it in the morning. 3. Makeup remover wipes shouldn’t be your first choice for cleaning Makeup remover wipes may be more convenient than normal makeup removers, but if you live in a highly polluted city, don’t rely on them to cleanse your skin. It’s better to use makeup remover oil or water, and do the cleaning steps obediently. 4. Use skin care products in different areas You don’t have to use the same product all over your face. Most people have combination skin. It is recommended to try to use fruit acid products on the T-zone that is prone to oil, which can effectively reduce acne outbreaks, and use moisturizing cream on other dry parts. 5. Remember to give skin care products time to absorb When you carry out the maintenance procedure again, give the superimposed skin care products 2~3 minutes of absorption time, so as not to be diluted or offset by the next product. 6. Be careful of the sun’s ultraviolet rays In fact, 90% of fine lines come from sun exposure. Sunscreen is the ultimate key to youthful skin. Remember to use products with SPF 30 or higher. 7. Exfoliate regularly Weekly chemical peels support healthy bacterial growth. Harsh exfoliants, on the other hand, have the opposite effect, triggering enzymes that destroy collagen. If it is the first time to contact chemical peeling, you can try fruit acid for normal skin, salicylic acid for oily or combination skin, and mild lactic acid for dry skin and sensitive skin. 8. Vitamin C is your best friend Vitamin C can whiten and lighten spots, mainly because vitamin C can block the synthesis of melanin, so that the skin that may be about to darken can be quickly restored to transparency, and the spots can be faded and no spots will appear. 9. Sweep away residual oil with a foaming face wash It is good for the facial cleanser to have bubbles, which can increase the suppleness and will not cause damage to the skin. However, a large number of bubbles or a facial cleanser that squeezes out bubbles may mean that the active interface agent is too strong and is not good for the skin. it is good. Before washing your face, it is safer to rub the foam on your hands. Do not squeeze the foam directly on the face to avoid excessive pulling on the skin. 10. Enhance the effectiveness of the mask The mask can promote the moisturizing factor to enter the skin. Before applying the mask, complete the original maintenance procedures, including lotion and essence, which will make the mask more effective. 11. Be patient with retinol The anti-aging maintenance ingredients in the past 10 years have almost all revolved around the ingredient Retinol (Retinol), which is also known as vitamin A, which can perfectly solve the fine lines and wrinkles on the skin. But using retinol is a marathon, not a sprint. It stimulates collagen, which also irritates the skin. Use after moisturizing, once a week. 12. Choose effective acne-fighting products Benzene peroxide (Benzoyl peroxide) can kill the bacteria in acne, and its 2.5% or 5.5% ingredients will not cause side effects, and can be used all over the face to prevent acne from growing. 13. Blackheads hate salicylic acid the most Salicylic acid really is your best weapon against blackheads and whiteheads, and if they’re driving you crazy, try using a face wash that contains salicylic acid and leave it on for 30 seconds before rinsing off.
