Daily skincare is the foundation for maintaining beautiful skin. However, within habits that we believe to be correct, there are often “bad habits” that can actually work against achieving healthy skin. Actions that seem harmless, such as overly strong cleansing, using skincare products in the wrong order, or insufficient sun protection, can accumulate and accelerate skin irritation and aging. In this article, we will provide a detailed explanation over 10 chapters of the common skincare mistakes to avoid, along with expert-recommended solutions for each.

Chapter 1: Overly Strong Cleansing and Its Negative Effects

The first step in protecting beautiful skin is “proper cleansing.” However, many people mistakenly believe that the more they cleanse, the better, which ultimately leads to skin damage. In particular, strong cleansers and excessive washing are the main causes of stripping away too much sebum, thereby damaging the skin’s protective barrier.

The skin has natural barriers, such as the sebum layer and intercellular lipids, which protect it from external irritants and dryness. Strong cleansers or frequent washing can strip away these barriers, leading to dryness, redness, and a stinging sensation. Additionally, removing too much sebum can trigger an overproduction of oil, often resulting in acne and clogged pores.

Furthermore, washing your face with hot water or using excessive friction is also one of the bad habits to avoid. Hot water quickly dehydrates the skin, while friction can damage the stratum corneum, leading to inflammation.

The following are suggested solutions for improvement:

• Limit cleansing to twice a day, morning and evening, and use lukewarm water.
  
• Choose a mildly acidic, low-irritant cleanser.
  
• Wash by gently enveloping your skin with泡 (foam), and rinse gently without rubbing.
  

By thoroughly practising correct cleansing, skin irritation improves, and transparency and smoothness are significantly enhanced.

Chapter 2: Incorrect Cleansing Methods

Cleansing is an essential step to remove makeup and sebum, but using the wrong method can have the opposite effect. Common mistakes include “using overly strong cleansers,” “rubbing for extended periods,” and “cleansing too many times.”

When using oil cleansers, rubbing vigorously places a significant strain on the skin. Additionally, attempting to remove waterproof makeup daily with a powerful cleanser can damage the skin’s protective barrier.

Excessive “double cleansing” is also problematic. While it should be done when necessary, making it a routine after every cleanse can lead to increased dryness and inflammation.

The following are suggested solutions for improvement:

• Choose the type of cleanser based on the intensity of your makeup.
  
• Use products that can remove makeup quickly without rubbing.
  
• Perform double cleansing only when necessary.
  

For those with sensitive or dry skin, milk-type or balm-type cleansers are recommended. These help minimize skin stress while removing only the necessary impurities, which is key to maintaining beautiful skin.

Chapter 3: Neglecting Sun Protection

The enemy of beautiful skin is “ultraviolet (UV) rays.” UV rays not only cause dark spots, wrinkles, and sagging, but they also damage the DNA of skin cells, accelerating the aging process. Despite this, many people do not use sunscreen correctly.

Common examples of bad habits are as follows:

• Not applying sunscreen on cloudy days or indoors.
  
• Focusing only on the SPF/PA value and neglecting proper application amount and reapplication.
  
• Relying on primer or foundation and skipping sunscreen.
  

UV rays shine through regardless of weather or season and can pass through glass and clouds. Therefore, using sunscreen year-round is essential.

The suggested solutions for improvement are as follows:

• Always apply sunscreen as the final step in your skincare routine every morning.
  
• Reapply every 2 to 3 hours.
  
• Do not forget sun protection even when working near windows indoors.
  

Additionally, using physical barriers such as hats, umbrellas, and sunglasses can further protect against photoaging. Sun protection is the most important step in safeguarding the future of your skin.

Chapter 4: Incorrect Moisturising Habits

Moisturising is the foundation of skincare, but many people use incorrect methods that can have the opposite effect. For example, relying solely on toner, excessively layering products to create a sticky feeling, or finishing with just an oil to seal in moisture.

Proper moisturising requires three key processes: “providing moisture,” “sealing with oils,” and “repairing the skin’s barrier function.” Toner alone can cause moisture to evaporate quickly, while oil alone leaves the skin lacking in hydration. The correct approach is to replenish moisture with toner, allow active ingredients to penetrate with serums or emulsions, and finally seal everything in with a cream.

Additionally, it’s important to pay attention to the choice of moisturisers. For dry skin, items rich in ceramides or hyaluronic acid are ideal, while for oily skin, lighter gel-type products are recommended. For sensitive skin, choosing formulations with low irritants is ideal.

The following three points are suggested solutions for improvement:

• Choose products that are suitable for your skin type.
  
• Use toner, emulsion, and cream in a balanced way.
  
• Adjust the amount of moisturiser according to the season and your condition.
  

Correct moisturising habits protect the skin from dryness and irritation, leading to soft, supple, and beautiful skin.

Chapter 5: Incorrect Skincare Order

The effectiveness of skincare is greatly influenced by the “order of application.” Many people overlook this step, wasting the beneficial ingredients in their products.

The basic principle is to apply products from the lightest texture to the heaviest. The ideal order is: toner → serum → emulsion → cream → oil. However, if the order is incorrect, active ingredients won’t reach the stratum corneum and will simply be repelled from the surface.

Common mistakes are as follows:

• Applying cream or oil first, which prevents the serum from penetrating.
  
• Applying multiple serums at the same time, causing the order to become mixed up.
  
• Following the same routine morning and night, without considering the skin’s condition.
  

The solution is to understand the characteristics of each product and follow the basic order of application. Additionally, in the morning, prioritise ingredients that focus on antioxidants and UV protection, while at night, emphasise repair and hydration. This approach allows for skincare that aligns with the skin’s rhythm during the day and night.

Simply applying products in the correct order can significantly enhance the effectiveness of the same products.

Chapter 6: Excessive Exfoliation

Exfoliation is effective for regulating the skin’s turnover and enhancing its clarity, but overdoing it can have the opposite effect. Frequent peeling or scrubbing can thin the stratum corneum, weakening the skin’s barrier function. As a result, dryness, redness, and stinging can worsen, leading to an increase in skin problems.

Additionally, it is important to avoid the habit of using highly刺激 (strong) peeling agents containing alcohol or strong acids on a daily basis. Disruptions in skin turnover are influenced not only by the thickness and dryness of the stratum corneum but also by UV damage and the effects of aging. Instead of aggressively removing the skin from the outside, it is crucial to support the skin’s natural ability to regenerate.

The following are suggested solutions for improvement:

• Limit exfoliation to once or twice a week.
  
• Choose a scrub with fine particles and low irritation.
  
• Start using products containing AHA or BHA at a low concentration.
  

By combining moderate exfoliation with proper moisturisation, you can refine the skin’s texture and restore its natural radiance and brightness.

Chapter 7: Lack of Sleep and Poor Stress Management

Even with a focus on skincare products, poor lifestyle habits can prevent you from achieving beautiful skin. In particular, lack of sleep and stress are major factors that cause significant damage to the skin.

During sleep, growth hormones are released, and skin turnover and repair are actively carried out. However, if sleep is insufficient, the repair process cannot keep up, leading to dryness, dark spots, and wrinkles. Additionally, continuous late nights can cause poor circulation, resulting in dull skin and persistent dark circles under the eyes.

Stress also negatively impacts the skin. When cortisol, the stress hormone, is excessively secreted, it can lead to an increase in sebum production and trigger inflammatory responses, making it more likely to develop acne and skin irritation.

The following are suggested solutions for improvement:

• Ensure 7 to 8 hours of quality sleep every night.
  
• Avoid using smartphones or computers before bed.
  
• Incorporate light exercise or meditation to manage stress.
  

Maintaining healthy lifestyle habits is the most effective and sustainable skincare.

Chapter 8: Nutritionally Imbalanced Diet

Beautiful skin is created from the inside out. Irregular eating habits and nutritional imbalances are major negative factors that cannot be compensated for, no matter how much effort is put into skincare.

What should be particularly avoided is excessive intake of carbohydrates and fats. Too much sugar triggers a “glycation reaction,” which damages collagen and elastin, leading to a loss of firmness and elasticity. Additionally, poor-quality fats can cause sebum oxidation, worsening clogged pores and acne.

On the other hand, the following nutrients are known to support beautiful skin:

• Vitamin C: Antioxidant properties, promotes collagen production.
  
• Vitamin E: Promotes blood circulation, protects against oxidative damage.
  
• Omega-3 fatty acids: Reduce inflammation and strengthen the skin’s barrier function.
  

Limiting processed foods and junk food, while focusing on a balanced diet, forms the foundation of healthy skin habits.

Chapter 9: Bad Habits like Drinking and Smoking

Drinking and smoking are major bad habits when it comes to maintaining beautiful skin.

Alcohol has a diuretic effect, which depletes the body’s moisture and leads to skin dryness. Additionally, by putting stress on the liver, it reduces detoxification function, making it easier for breakouts and dullness to appear on the skin.

Smoking is even more serious. Nicotine constricts blood vessels, slowing down blood flow and making it harder for oxygen and nutrients to reach the skin. Additionally, the free radicals produced by smoking break down collagen, leading to deep wrinkles and sagging.

The following are suggested solutions for improvement:

• Consume alcohol in moderation (a few times a week, in small amounts).
  
• Stay hydrated by drinking plenty of water while consuming alcohol.
  
• Make efforts to quit smoking or reduce the number of cigarettes smoked.
  

To regain skin’s transparency and elasticity, it is essential to reassess and eliminate these harmful habits.

Chapter 10: Forgetting to Remove Makeup

Going to bed without removing makeup at the end of the day is one of the worst habits for the skin. Leftover makeup and sebum oxidise, producing free radicals that can cause inflammation and dark spots. Additionally, they can clog pores, increasing the risk of acne and blackheads.

Moreover, sleeping with makeup on disrupts the skin’s turnover, leaving the skin rough and prone to dullness the next morning. This daily accumulation accelerates skin aging.

The solution is simple:

• Always cleanse your face before going to bed.
  
• On tired days, use sheet masks or balm-type cleansers for quick and efficient care.
  
• Ensure thorough moisturisation with night skincare before going to bed.
  

Removing makeup is a “ritual to reset the skin” and can be considered the minimum requirement for maintaining beautiful skin.

Conclusion

Bad skincare habits that hinder beautiful skin stem from small lapses or misunderstandings in daily routines. Overly strong cleansing, incorrect makeup removal, insufficient sun protection, mistakes in moisturising and order of application, and poor lifestyle habits all accumulate, leading to undeniable damage to the skin.

However, by reviewing each of these habits, the skin can regain its natural health and beauty. Acquiring the correct knowledge and improving daily skincare routines and lifestyle habits is the quickest route to achieving beautiful skin.
