【Mother's Day Special Survey】87.2% of 500 Mother-Daughter Pairs Feel 'Inherited Skin Concerns' | Inheritance Rate of Spots, Moles, and Melasma, and 3 Prevention Strategies

【Conclusion】Key Points of This Survey In conclusion, while the 'tendency to develop' spots and moles is largely influenced by genetic factors, it is possible to prevent their onset. Melasma tends to be inherited from mother to daughter; the survey found that 68.4% of daughters whose mothers had melasma also had similar symptoms. However, dermatological science has proven that even with a genetic predisposition, the risk of onset can be significantly reduced through UV protection and appropriate skincare.

・87.2% of 500 mother-daughter pairs responded that they 'have the same skin concerns,' realizing the inheritance of skin quality. ・The most commonly felt inherited skin concern was 'tendency to develop spots' (52.8%), followed by 'abundance of moles' (41.6%). ・68.4% of daughters whose mothers had melasma also developed similar melasma symptoms, indicating a significant genetic influence.

Terminology Explanation ■ What is Melasma? Melasma is a type of brown spot that frequently appears symmetrically on the cheekbones and forehead of women in their 30s and 40s. Fluctuations in female hormones are involved in its onset, often triggered by pregnancy, childbirth, or the use of oral contraceptives. It tends to worsen with UV exposure and friction, and its treatment differs from that of ordinary spots.

What is Melanin Production Capacity (Melanocyte Activity)? Melanin production capacity refers to the ability of skin pigment cells (melanocytes) to produce melanin pigment. This ability is largely genetically determined, and skin types with high melanin production capacity tend to develop spots easily due to UV exposure.

What is Photoaging? Photoaging refers to the damage accumulated in the skin due to long-term UV exposure. It is a major cause of spots, wrinkles, and sagging, and is distinct from natural aging due to chronological age. Photoaging tends to progress more easily in skin types that are genetically highly sensitive to UV.

Comparison of Skin Concerns with High Genetic Factors vs. High Acquired Factors Type of Skin Concern | Degree of Genetic Influence | Degree of Acquired Influence | Possibility of Prevention ---|---|---|--- Number/Location of Moles | Very High (70-80%) | Low (20-30%) | Difficult to suppress occurrence, but possible to prevent malignancy Tendency to Develop Spots | High (50-60%) | Moderate (40-50%) | Can be significantly reduced with UV protection Melasma | High (50-70%) | Moderate (30-50%) | Can be reduced with hormone management and avoiding friction Freckles | Very High (80% or more) | Low (less than 20%) | Difficult to suppress occurrence, but possible to prevent worsening Tendency for Dry Skin | Moderate (40-50%) | High (50-60%) | Can be significantly improved with skincare Tendency for Visible Pores | Moderate (40-50%) | High (50-60%) | Can be improved with lifestyle habits and skincare *These are general guidelines and individual differences exist.

I.C. Clinic, operated by Medical Corporation Tetsuyui-kai (Shinjuku, Shibuya, Ueno, Ikebukuro, Tokyo, Omiya branches), conducted a survey on 'inherited skin concerns' between mothers and daughters ahead of Mother's Day on May 11, 2026. This survey targeted 500 mother-daughter pairs (total 1,000 individuals) nationwide to investigate the reality of common skin concerns between parents and children and their awareness of inheritance, providing scientific explanations from a dermatologist's perspective.

Survey Background Comments like 'I'm developing the same spots as my mother' or 'My abundance of moles is inherited from my parents' are commonly heard in dermatology clinics. Interest in the genetic factors of skin quality and concerns is increasing year by year, and many women particularly feel the similarity in skin quality between mothers and daughters. However, accurate information is lacking regarding what is inherited to what extent, and whether prevention or treatment is possible even with a genetic predisposition. This survey was conducted with the aim of clarifying the reality of inherited skin concerns and providing scientifically based prevention and countermeasure information, taking advantage of Mother's Day as an opportunity to consider parent-child bonds.

Survey Overview Target: Mother-daughter pairs aged 20-50 nationwide (mothers 40-70s, daughters 20-50s) with skin concerns. Survey Period: April 13, 2026 - April 22, 2026 Survey Method: Internet survey Number of Respondents: 500 individuals

Survey Results 【Survey Result】87.2% of Mother-Daughter Pairs Feel 'Having the Same Skin Concerns' Question: Do you feel that you and your mother (or daughter) have the same skin concerns? It was revealed that nearly 90% of mother-daughter pairs feel a commonality in skin concerns. Many of the 42.6% who responded 'strongly feel' included cases where even the location of spots and moles felt similar, indicating a high level of interest in genetic factors.

【Survey Result】'Tendency to Develop Spots' is Top at 52.8% for Felt Inheritance, Followed by 'Abundance of Moles' at 41.6% Question: What skin concern do you feel is most 'inherited'? (Select one) Pigment-related skin concerns like spots and moles topped the list. This is dermatologically reasonable, as melanin production capacity and melanocyte activity are known to have significant genetic factors.
