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
genotype | Skin Features | Optimal skin care |
COL1A1 mutation present | Prone to wrinkles and sagging | Cosmetics containing vitamin C and retinol |
Decreased SIRT1 activity | Easy to dry out and age easily | Skin care containing resveratrol and niacinamide |
MC1R mutation present | Prone to spotting due to UV rays | High SPF sunscreen, antioxidant serum |
2. Custom skin care using genetic testing
Recently, a service has emerged that suggests personalized skincare products based on genetic testing. By selecting beauty ingredients that match one’s genotype, more effective skin care can be achieved.
Interaction between genes and lifestyle
Genes influence skin aging, but they are not the only factors that determine skin youthfulness. Lifestyle and environmental factors are also involved in gene expression, and proper management of these factors can delay skin aging.
1. Diet and Skin Health
Considering the impact of genes on skin aging, active intake of certain nutrients can help keep the skin young.
Nutrients for skin and their functions
nutrient | Major Foods | Effects on skin |
vitamin C | Citrus fruits, bell peppers, broccoli | Promotes collagen production, antioxidant action |
vitamin E | Nuts, avocado, olive oil | Reduction of UV damage, skin moisturizing |
omega-3 fatty acid | Salmon, chia seeds, walnuts | Reduces inflammation and maintains skin elasticity |
polyphenol | Green tea, red wine, blueberries | Antioxidant action, epigenetic regulation of gene expression |
Coenzyme Q10 | Meat, soybeans, fish | Mitochondrial activation, improved skin energy metabolism |
2. Stress and skin aging

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
Personalized beauty using genetic testing
In recent years, personalized beauty using genetic testing has been attracting attention. Based on an individual’s genetic information, optimal skincare and lifestyle recommendations can be made, enabling more efficient aging care.

Real-life examples of skin quality improvement using genetic testing

Many successful skin care and lifestyle modifications based on genetic testing have already been reported. Here are some specific examples of how genetic information can be used to maintain skin youthfulness.
1. Cases of genotypes with low UV tolerance (MC1R mutation)
background
Ms. A, a 35-year-old woman, had been prone to freckling since childhood and had a reddish skin tone that quickly turned red when she got sunburned. Genetic testing revealed that she had a mutation in the MC1R gene and low protection against UV rays.
Practiced Care
- Use SPF 50+ sunscreen daily and reapply every 2 hours
- Active intake of antioxidant vitamins C and E
- Repair DNA damage with niacinamide serum
- Wear a UV hat and sunglasses
result
After 6 months, the incidence of skin blemishes has decreased and the color of freckles has faded. In addition, UV-induced redness was reduced and the overall skin tone became more even.
2. Case of a genotype with rapid collagen degradation (COL1A1 mutation)
background
Mr. B, a male in his 40s, had rapidly developed sagging skin and fine wrinkles since his late 30s. Genetic testing revealed that he had a mutation in the COL1A1 gene and was a type that degrades collagen quickly.
Practiced Care
- Collagen peptide supplements taken daily
- Introduce skin care containing retinol to promote turnover
- Moisturizing care including hyaluronic acid to enhance skin moisture retention
- Conscious of high-protein diet (chicken, fish, eggs)
result
After four months, fine lines and wrinkles were less noticeable and skin elasticity improved. Six months later, sagging of the facial line also decreased, giving a more youthful appearance.
3. Cases of genotypes with low antioxidant capacity (SOD2 mutation)
background
Ms. C, a 50-year-old woman, was concerned about the dullness of her face and the roughness of her skin. Genetic testing revealed that she had a mutation in the SOD2 (superoxide dismutase) gene and low antioxidant capacity in her body.
Practiced Care

- Using a serum that combines astaxanthin and vitamin C
- Facial massage to promote blood circulation
- Detox in hot springs and saunas on a regular basis
result
After 3 months, skin dullness was reduced and clarity improved. Blood circulation improved and skin became plumper and softer.
Skin aging mechanism at the genetic level

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

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
