youthful appearance
- Appearance youthfulness is determined by multiple factors such as skin, hair, body shape, and posture.and genetic factors are largely involved.
- C-type mutation in DNA region rs7556898A National Taiwan University study found that people with this condition tend to look younger.
- The prevalence of type C mutation (CC+CT) in Japanese people is86.9%This is almost the same level as the world average of 85.4%.
Overview Youthful appearance is a result of a complex interplay of many factors, including health, beauty, lifestyle, genetics, and the environment. The biggest influence is on the condition of your skin, with firmness, elasticity, wrinkles, sagging, and age spots all influencing your youthfulness. These are affected by UV rays, free radicals, and age-related changes, so proper skin care, sunscreen, moisturizing, and antioxidant intake can help maintain youthful skin. The shine, volume, and color of your hair also emphasize your youthful appearance, and a balanced diet and proper hair care are necessary to counter age-related changes. Additionally, your body shape and posture play an important role in your youthful appearance, and regular exercise, strength training, and a balanced diet will help you maintain your ideal body shape and posture. Mental health also has a big impact, and things like getting enough sleep and managing stress can affect your appearance. Genetic factors also play a large role in how young you look. The skin, hair, and constitution inherited from your parents have a major impact on the speed of aging and appearance. A study by Lin et al. at National Taiwan University revealed that a younger appearance is associated with a DNA region called rs7556898. There are three genotypes in this DNA region: CC, CT, and TT, and it has been found that people with type C mutations tend to look younger.
What does it mean to look young?
Youthful appearance refers to the youthful appearance that is determined by multiple factors such as skin firmness, wrinkles, and age spots, hair gloss, body shape, and posture.Genetic factors, ultraviolet rays, and lifestyle habits have a complex effect and influence the speed of aging.
4 factors that determine how young you look
Looking young is shaped by four main factors: We will explain each factor and countermeasures.
①Skin condition
- Impact:Firmness, elasticity, wrinkles, sagging, and age spots affect youthfulness.
- Cause:Collagen decrease due to UV rays, free radicals, and aging
- Measures:Sunscreen, moisturizer, and intake of antioxidants (vitamin C, E, etc.)
② Hair shine and volume
- Impact:The shine, volume, and color of your hair greatly affect your appearance age.
- Measures:Balanced diet (protein, zinc, iron) and proper hair care
③Body shape and posture
- Impact:Maintaining your body shape and correct posture gives you a youthful look
- Measures:Regular exercise, strength training, balanced diet
④ Mental health
- Impact:Stress and lack of sleep directly affect appearance, such as rough skin and dullness.
- Measures:Adequate sleep (7-8 hours), stress care (meditation, moderate exercise)
Comparison of factors that affect youthful appearance
| factor | degree of influence | Main measures |
|---|---|---|
| skin condition | very high | UV protection, moisturizing, and intake of antioxidants |
| hair shine | expensive | Balanced diet and proper hair care |
| Body shape/posture | expensive | Regular exercise/strength training |
| mental health | medium to high | Adequate sleep/stress care |
| genetic factors | expensive | Know your constitution with a DNA test |
The relationship between genes and youthful appearance
Why does genetics have something to do with looking young?
The skin, hair, and constitution inherited from your parents directly affect the speed of aging and your physical age.Due to genetic factors, there are individual differences in how young people look even at the same age.
Relationship between DNA region rs7556898 and youthful appearance
Research by Lin et al. at National Taiwan University (2022, J Gerontol A Biol Sci Med (published in Sci) revealed that youthful appearance is associated with the DNA region rs7556898.
- There are three genotypes of rs7556898: CC, CT, and TT.
- Genotype with type C mutation(CC type/CT type) people tend to look younger.
- This gene region is related to the FIGN gene
Comparison of genotype distribution in Japanese and the world (rs7556898)
| Genotype | Percentage of Japanese people | percentage of the world |
|---|---|---|
| CC type | 40.8% | 38.4% |
| CT type | 46.1% | 47.0% |
| TT type | 13.0% | 14.4% |
The prevalence of type C mutation (CC+CT) in Japanese people is86.9%This is almost the same level as the world average of 85.4%. The percentage of Japanese people with type TT is13.0%This is slightly lower than the world average of 14.4%.
Rationale for testing
Surface DNA region: youthful appearance
The gene region that most strongly influences youthful appearance is rs7556898. The distribution of isomorphic genotypes in Japan is as follows.
- CC 40.8 %
- CT 46.1 %
- TT 13.0 %
Basis for inspection
A study by Lin and colleagues at National Taiwan University revealed that looking younger is linked to genes. There is a region called rs7556898 in the human genome, and the gene in that region has two types of mutations, C and T. It was found that people with the type C mutation tend to look younger.
