Detailed answer

To prevent blackheads on the neck, it's important to exfoliate regularly and keep the skin clean. Exfoliating helps to remove dead skin cells and unclog pores, which can contribute to the formation of blackheads. Use a gentle exfoliating scrub or a chemical exfoliant with ingredients like salicylic acid or glycolic acid. Cleanse the neck area thoroughly with a gentle cleanser twice a day to remove dirt, oil, and bacteria. Avoid using heavy moisturizers or oils that can clog pores. Additionally, wearing loose-fitting clothing made of breathable fabrics can reduce sweating and irritation on the neck, helping to prevent blackheads. Remember to always moisturize the neck area with a lightweight and non-comedogenic moisturizer to keep the skin hydrated without blocking the pores.
