Detailed answer

Toners are primarily used to balance the pH levels of the skin and remove residual impurities after cleansing. While they can enhance overall skin texture and tone, they are not specifically designed to target stretch marks. Stretch marks occur due to the stretching of the skin beyond its capacity, and they require specialized treatments to improve their appearance. Retinoids, chemical peels, microdermabrasion, and laser therapies are some commonly used methods for reducing the appearance of stretch marks. Consulting with a dermatologist would be the best approach to explore suitable options for stretch mark reduction on the thighs.
