Based on the frequency of appearance of SNPs and biochemical knowledge, the SNPs used for the learning model were selected, and from the created learning models, a learning model with a high AUC was selected while using the SNPs.
  • SNPs listed above are the SNPs used in the aging model formula for each skin condition, respectively.

  • Example 6 Evaluation of skin aging resistance Obtaining SNP information acquired from a subject, cell active power, skin shielding power, face shape modeling power, metabolism maintenance power, skin color assist power, stimulation protection power, damage control power, Scores were calculated for each of the aqua vitamin utilization ability and the oil vitamin utilization ability based on the phenotype and genetic model of each SNP. Specifically, scores were given for each SNP phenotype according to the table below. Three resistances with low scores were selected, and the three resistances recommended for the subject to prevent and strengthen the resistance. Preventive measures against aging can be proposed for the three low-scoring resistances.
  • Example 7 Verification of evaluated skin resistance Three types of skin aging resistance that we recommend customers to prevent and strengthen by clarifying the strength and balance of nine types of skin resistance to aging from the results of genetic tests. We have developed an algorithm to propose power. The effectiveness of this algorithm was verified based on the genetic test results, skin measurement results, and skin trouble questionnaire results of the subjects (about 1500 persons). Specifically, for the SNPs possessed by the subjects, the resistance of each skin of the subjects to aging was scored according to the definitions in Tables 25 and 26. In addition, when the three powers cannot be defined only by the genetic test results, we succeeded in narrowing down the resistance to skin aging by using the results of nine kinds of skin trouble questionnaires originally created by the present inventors.
  • this algorithm newly developed by the present inventors supports the improvement of the balance of resistance to skin aging according to the customer's personalized skin constitution and skin troubles, and is the core of the service newly developed by us. It shows that it is appropriate as a technology.
  • Example 8 Example showing the effectiveness of the method for determining the resistance to skin aging of the present invention
  • the daily intake of water-soluble vitamins is shown in Table 27.
  • Table 28 shows the degree of stains on both sides. Subjects with higher intake of water-soluble vitamins have less stains. This shows the effectiveness of the method for determining the resistance of the present invention, and is an example in which the influence of skin aging due to SNP is reduced by living according to the resistance.
