[Don't be fooled by expensive cosmetics!] [Are supplements a waste for rejuvenation?!] A doctor talks about anti-aging
1. Skincare and basic skin management focusing on "active ingredients over price"
"Active ingredients over price" in skincare and basic skin management. When choosing skincare products, we tend to be attracted by the price and choose expensive cosmetics, but in reality, there is not much correlation between price and effectiveness. Research conducted in the United States has revealed that there is no statistical difference in skin moisture or elasticity between luxury cosmetics costing over 10,000 yen and general cosmetics costing under 3,000 yen. This finding provides an answer to the question many consumers feel: "Are expensive cosmetics really effective?" What is important is not the price, but the "active ingredients." For example, choosing products that contain ingredients considered effective for improving skin hydration and anti-aging, such as hyaluronic acid or retinol, is effective for actual skin improvement. I have also tried luxury cosmetics, but in the end, my skin condition stabilized after switching to affordable products that contain simple, proven ingredients. Furthermore, it is important to make skincare a habit. Rather than using expensive products occasionally, it is most effective to continue using items that suit your skin in your daily skincare routine. The skin repeats repair and regeneration according to its turnover (metabolism) cycle, so it is ideal to perform long-term care that matches that cycle. In this respect, continuous daily care is the key to maintaining youthful and healthy skin. Overall, the most important things in skincare are "ingredient selection" and "habituation." By choosing effective ingredients even if they are inexpensive, you can expect reliable skin improvement with less financial burden and continuous use. From now on, let's make witty choices without being misled by advertisements or labels.
In daily skincare, the most important thing to prioritize is the active ingredients rather than the price of the cosmetics. In fact, I tried creams from luxury brands, but I found that as long as they contained evidence-based ingredients like hyaluronic acid or retinol, even affordable products provided sufficient hydration and elasticity. US studies have reported that no significant difference in skin moisture or elasticity was observed between luxury products costing over 10,000 yen and products costing a few thousand yen. This is interesting evidence for doctors to use when guiding patients.
Hyaluronic acid enhances moisture retention, and retinol contributes to collagen production and the promotion of turnover. Incorporating these ingredients continuously into your daily care is essential for strengthening the skin's barrier function. Personally, I feel that my skin texture is easier to refine by consistently using products that are easy to use every day rather than occasionally performing expensive "special care."
From a doctor's perspective, many skin problems are caused by incorrect product selection or usage frequency. Therefore, it is good to first recommend products that emphasize active ingredients to patients and instruct them to switch promptly if the product does not suit their skin type. And above all, it is important to make that care a habit without strain and continue using it according to the skin's turnover cycle. This can be said to be effective skincare based on scientific evidence.
At my clinic, patients often ask me if they should use expensive items. However, in reality, price and effectiveness are not always proportional, and the foundation is to correctly select ingredients according to your skin type and goals and to perform daily skincare appropriately. When I provide guidance based on this, many people can continue without difficulty, and the recurrence rate of skin problems has decreased.
2. Correct use of supplements and dietary management
Although there are many voices expecting anti-aging effects from supplements, in reality, sufficient evidence has not been obtained for supplements alone. Results from large-scale cohort studies, including those in the New England Journal of Medicine, have reported that there is no clear causal relationship that health, longevity, or anti-aging is significantly promoted solely by taking specific supplements. I have personally tried vitamin C and multivitamins for a certain period, but I did not get dramatic physical effects from them alone.
However, this does not mean that supplements are completely meaningless. Vitamin D and omega-3 fatty acids are representative examples of nutrients that are easily deficient in modern diets. By supplementing with appropriate amounts, benefits that I can recommend as a doctor, such as immune support and reduction of cardiovascular risk, can be expected. However, it is important to emphasize to patients that they play an "auxiliary" role.
On the other hand, the key to true rejuvenation and health maintenance lies in a balanced diet. A combination of colorful vegetables and fruits, high-quality protein, and moderate carbohydrates is the basis, and it adjusts the intestinal environment and metabolic functions in total. I usually incorporate vegetable-centered menus for breakfast and choose fish, chicken, and soy products for lunch and dinner. On top of that, I feel that supplementing with nutrients that tend to be lacking improves the stability of my physical condition.
When providing patient guidance as a doctor, it is essential to advise them not to fall into supplement dependency and to first recommend reviewing their diet. Creating a habit of adjusting the total nutritional balance while making good use of supplements will ultimately lead to anti-aging and healthy longevity.
3. Quality sleep: Optimization of hormone secretion and repair functions
Quality sleep is a very important factor from an anti-aging perspective. During deep non-REM sleep, growth hormone is actively secreted, which contributes significantly to the repair of cells in the skin, muscles, and even internal organs. In the past, when my sleep schedule was irregular due to being busy, I often noticed skin firmness and physical fatigue when I woke up in the morning. However, since I started taking measures such as adjusting my sleep rhythm and refraining from using my smartphone before bed, I have felt that waking up the next morning has become much better and my skin condition has stabilized.
From a doctor's point of view, sleep hygiene guidance for patients is essential for the prevention of lifestyle-related diseases and anti-aging care. Specifically, I advise keeping the room temperature at 18–20°C and humidity at 50–60%, and I recommend minimizing the use of smartphones or PCs one hour before bedtime to avoid blue light that interferes with falling asleep. Also, keeping bedtime and wake-up times constant to reset the biological clock is effective in improving sleep quality.
Such guidance can also be applied to anti-aging outpatient clinics in dermatology and orthopedics. There are many patients who think, "I should just rely on cosmetics and supplements," but in reality, quality sleep is what regulates hormonal balance and is also significantly involved in improving immunity and promoting metabolism. As a result, it is a major key to promoting the regeneration of skin and muscles and maintaining youthfulness.
4. Exercise habits: HIIT (High-Intensity Interval Training) and aerobic exercise
High-Intensity Interval Training (HIIT) is a training method recommended for busy people and those who are not good at exercise because it can efficiently train the body even in a short time. Specifically, just repeating a few sets of 1 minute of all-out exercise and 2 minutes of rest can be expected to improve cardiopulmonary function and improve metabolic rate. When I tried incorporating HIIT during work breaks, I felt that not only did my body fat decrease, but my concentration during the day increased and my skin condition improved. As a doctor, I feel that HIIT is easy to propose to patients who want to get results in a short, intensive period.
On the other hand, for middle-aged and older people or those who have not had exercise habits, light aerobic exercise such as walking is recommended. Continuing to walk for about 20 to 30 minutes is thought to contribute to the activation of mitochondria and improvement of blood flow, as well as the rejuvenation of skin and internal organ functions. At my clinic, I often recommend starting with walking and gradually increasing the intensity. Continuing within a reasonable range and having the patient work on it positively will ultimately lead to anti-aging effects.
Furthermore, counseling regarding the time of day to exercise is also important. While morning exercise is said to have the effect of resetting the biological clock and increasing metabolism, evening exercise is reported to be more likely to lead to muscle strength improvement and performance enhancement. By finding the optimal exercise time together according to the patient's lifestyle and occupation, the continuation rate is greatly improved. Such exercise guidance should become a pillar of health management that spans many areas, as part of lifestyle-related disease prevention, mental health improvement, and anti-aging care.
5. Mental care and lifestyle: Mindfulness, laughter, and contact with nature
Mindfulness meditation has been reported to reduce cellular aging markers and help maintain telomere length with just 5 minutes of practice per day for 6 weeks, and it is also expected to have a suppressive effect on cortisol, a stress hormone. When I incorporated 5 minutes of meditation every morning during a period of increased work stress, my mind became clearer, and my daytime irritability and lack of focus were significantly reduced. From a physician's perspective, suggesting mindfulness as part of mental care for patients is considered highly useful for the anti-aging of both mind and body, as well as for the prevention of lifestyle-related diseases.
On the other hand, laughter is also an important element that contributes to anti-aging. Even if you don't have many opportunities to laugh out loud, simply being conscious of forced laughter can suppress cortisol secretion and potentially boost immune function. It would be effective to have patients make a habit of behaviors that induce laughter, such as watching comedy movies or comedy shows. Additionally, taking walks in nature, such as in parks or forests, has the significant benefit of regulating the autonomic nervous system and stabilizing blood pressure and heart rate. In my own case, when I continued the habit of walking in a nearby forest during a period when I was easily fatigued, I felt that my sleep quality improved and my morning wake-ups became refreshing. These mental care and lifestyle improvement methods can be widely utilized in medical settings and are easy for patients to incorporate at their own pace. As a result, cellular-level repair functions are enhanced, leading to the creation of a foundation for maintaining youthfulness.
Summary
Rejuvenation and anti-aging are difficult to achieve with only "special high-priced products" or "extreme detoxes," and a comprehensive approach based on evidence-based skincare, nutritional management, exercise, sleep, and stress management is important.
To achieve rejuvenation and anti-aging, relying solely on expensive cosmetics or extreme detox methods is insufficient; a comprehensive approach based on scientific evidence is essential.
First, in skincare, it is effective to prioritize active ingredients like hyaluronic acid and retinol over price and incorporate them into your daily routine.
Second, rather than becoming overly dependent on supplements, a balanced diet remains the fundamental prerequisite, while incorporating nutrients that tend to be lacking, such as Vitamin D and Omega-3 fatty acids, as a "supplementary" measure.
Third, by ensuring high-quality sleep, it is possible to promote the secretion of growth hormones and maximize the repair functions of the skin and muscles.
Fourth, by continuing aerobic exercises such as HIIT, which provides high effects in a short time, or walking, you can improve cardiopulmonary function and metabolism, maintaining youth and vitality.
Finally, reducing stress through mindfulness meditation, laughter, and contact with nature also contributes to preventing aging at the cellular level.
By using these five points as pillars and providing guidance tailored to the patient's daily life, we can propose an evidence-backed, sustainable rejuvenation program. As a doctor, it is important to support patients in reviewing their entire lifestyle while setting reasonable goals and conducting regular follow-ups. It is believed that only through a comprehensive perspective and flexible individual responses can long-term and tangible anti-aging effects be obtained.
