Wrinkles that come and go are often due to dehydration, sun exposure, or temporary skin dryness rather than permanent ageing. When your skin is well-hydrated, they improve, and when it becomes dry or stressed, they reappear. Focus on a simple routine: use a good moisturiser, drink enough water, and apply sunscreen daily to prevent damage. You can also use products with hyaluronic acid for hydration and retinol (at night) to improve skin texture over time. If the problem persists, a dermatologist can suggest stronger treatments based on your skin type.
