Across the sources, dermatologists commonly advise a simple, consistent regimen rather than complex multi-step routines: a gentle cleanser, an antioxidant serum (vitamin C), a retinoid/retinol, moisturizer, and daily broad-spectrum sunscreen. Guidance frames topical ingredients as a way to slow or reduce the appearance of fine lines, uneven tone, roughness and dryness, with daily sun protection emphasized as foundational. Expert consensus efforts (e.g., the Northwestern dermatologist survey of 23 ingredients) are cited as practice patterns identifying the most expert-supported ingredients.

The sources are largely US-based and do not give India-specific guidance; however, the consistent emphasis on daily broad-spectrum/mineral sunscreen and niacinamide/vitamin C for uneven tone and pigment is especially relevant for India's high sun exposure, hot climate and pigmentation-prone skin, where sun protection and tone-evening ingredients are commonly prioritized.
