The homecare routine is honestly just as important as the professional treatments themselves, so it's great that you're thinking about this. At minimum, you should be using a gentle cleanser, a treatment product with active ingredients, a moisturizer, and a broad-spectrum SPF 30 or higher every single day. The specific ingredients you need depend on your skin concerns - for anti-aging, look for retinol or retinoids, vitamin C, and peptides. For acne-prone skin, ingredients like salicylic acid, benzoyl peroxide, or niacinamide are helpful. For hyperpigmentation, vitamin C, kojic acid, or azelaic acid can be beneficial. As for professional-grade versus drugstore products, there is generally a difference in quality and concentration of active ingredients. Medical-grade products typically have higher concentrations of active ingredients and better formulations that help with penetration and stability. That doesn't mean drugstore products are useless, but if you're investing in professional treatments, using quality products at home will definitely enhance and extend your results. For treatment frequency, it depends on what treatments you're getting and your skin concerns. Some people do well with monthly facials, while others might need treatments every six to eight weeks. Your aesthetician should be able to recommend an appropriate schedule based on your specific needs and goals.
