Genetic Information and How to Keep Skin Young

Posted on 2025年 1月 13日

Recent studies have shown that genetic factors are deeply involved in skin aging. Understanding the influence of genes and practicing skin care and lifestyle habits based on this understanding can delay skin aging. This article details the genes that are important in maintaining skin youthfulness, their functions, epigenetics (acquired changes in gene expression), and beauty strategies that utilize them.

Genes involved in skin aging

Both external factors, such as UV radiation and oxidative stress, and genetic factors are involved in skin aging. In particular, the following genes are considered important in maintaining skin youthfulness

1. COL1A1 gene (collagen production)

The COL1A1 (collagen type I alpha 1 chain) gene is responsible for collagen production, which is important for skin elasticity and firmness. Mutations in this gene cause collagen to degrade more easily, leading to wrinkles and sagging skin.

Methods to activate the COL1A1 gene

  • Consume foods high in vitamin C (citrus fruits, bell peppers, broccoli)
  • Use of skin care products containing retinol (vitamin A derivative)
  • Thoroughly protect against ultraviolet rays and prevent collagen degradation

2. SIRT1 gene (longevity gene)

The SIRT1 (Sirtuin 1) gene is responsible for preventing cellular aging and promoting DNA repair. When the activity of this gene is reduced, the skin’s ability to repair itself is impaired, resulting in the development of wrinkles and sagging skin.

How to activate the SIRT1 gene

  • Resveratrol (red wine, grapes, peanuts)
  • Moderate calorie restriction (fasting)
  • Incorporate foods containing polyphenols (cacao, green tea)

3. MC1R gene (resistance to UV damage)

The MC1R (melanocortin 1 receptor) gene is involved in skin color and resistance to UV light. Mutations in this gene make the skin more susceptible to UV damage and increase the risk of spots and wrinkles.

How to prevent UV damage

  • Use sunscreen (SPF 30 or higher) daily
  • Consume foods with antioxidant properties (tomatoes, blueberries)
  • Protect against UV rays with hats and sunglasses

Epigenetics and skin youth

The function of genes is not fixed at birth, but is altered by lifestyle and environment. This phenomenon is called “epigenetics. In order to maintain skin youthfulness, it is important to direct epigenetic changes in a positive direction.

1. Methylation and histone modification

DNA methylation and histone modifications serve to switch genes on and off. This can delay skin aging and enhance repair functions.

How to take advantage of epigenetics

  • Consume foods high in folic acid and B vitamins (spinach, liver)
  • Make moderate exercise a habit and improve blood flow
  • Manage stress and reduce cortisol secretion

Genetically Based Skin Care Strategies

Understanding the genetic characteristics of the skin and applying the appropriate skincare regimen can make aging more effective.

1. How to choose skin care by genotype

Stress is one of the factors that accelerate skin aging. In particular, chronic stress increases cortisol (stress hormone) secretion and accelerates collagen degradation.

How to Manage Stress

  • Incorporate mindfulness meditation (inhibits the release of stress hormones)
  • Deep breathing and yoga to regulate the autonomic nervous system
  • Ensure adequate sleep and promote skin repair
  • Drink relaxing herbal teas (chamomile, lavender)

3. Exercise and skin rejuvenation

Moderate exercise helps maintain youthful skin by stimulating blood flow and providing the skin with the oxygen and nutrients it needs.

Good exercise habits for skin

  • Aerobic exercise (walking, jogging) → enhances blood circulation and antioxidant activity
  • Strength training (squats, dumbbell exercises) → Promotes secretion of growth hormone and supports skin regeneration
  • Yoga and stretching → Stress reduction, hormonal balance adjustment

Skin aging mechanism at the genetic level

憂鬱な表情の高齢者女性

1. Relationship between telomere shortening and skin aging

There is a limit to the number of times a cell can divide, and an indicator of this is the telomere (structure at the end of chromosomes). When telomeres become short, the ability of cells to divide decreases and skin turnover is delayed, causing wrinkles and sagging.

How to slow telomere shortening

  • Omega-3 fatty acids (salmon, nuts)
  • Make moderate exercise (aerobic and strength training) a habit
  • Reduces stress and improves sleep quality

2. Mitochondrial dysfunction and lack of skin energy

As mitochondria, which are responsible for the energy production of skin cells, decline, collagen production and repair functions are impaired. In particular, recent studies have shown that a decrease in NAD+ (nicotinamide adenine dinucleotide) is involved.

How to Activate Mitochondria

  • Consume foods that increase NAD+ (edamame, avocado, yeast)
  • Moderate fasting (Intermittent Fasting) to activate mitochondria
  • Use of coenzyme Q10 supplements

By utilizing epigenetics (acquired changes in gene expression), even those who are genetically at risk for skin aging can maintain youthful skin with proper care.

1. Histone Modification and Skin Care

Histone modifications are an important epigenetic mechanism that regulates gene expression. It is believed that by modulating histones, the expression of aging-related genes can be reduced.

Nutrients that promote histone modification

  • Sulforaphane (broccoli) → antioxidant action, DNA repair promotion
  • Resveratrol (red wine, grapes) → activation of sirtuin gene
  • EGCG (green tea) → Inhibits inflammation and prevents cellular aging

As epigenetics research progresses, it is expected that new skin care products targeting histone modifications will be developed in the future.


2. Epigenetic changes due to lifestyle

Good habits improve gene expression in the skin.

  • Regular diet → regulates genetic methylation and prevents skin aging
  • Moderate exercise → promotes epigenetic changes and supports cell rejuvenation
  • Stress management → reduces cortisol overproduction and prevents skin inflammation

On the other hand, smoking and excessive UV exposure are considered habits that should be avoided because they disrupt gene methylation and accelerate aging.
