Reactive hypoglycemia and wrinkles?

- glucose dropped to 3.5 mmol/L at 120 min

Other findings:

- chin hair growth
- hair loss

- bloating
- mild diarrhea sometimes
- sleep problems
- headaches

Question:
Has anyone with reactive hypoglycemia noticed that their skin suddenly became more wrinkled / aged-looking despite a very good skincare routine?

I feel like my face changed a lot recently and I’m wondering if this could be more internal (hormones, insulin, inflammation, cortisol, nutrient deficiencies etc.) rather than a skincare issue.
Do You think can it be reversed if I follow a good diet and sport routine?
