How do I build a skincare routine from scratch?

Start with three essentials: a gentle cleanser matched to your skin type, a basic moisturizer, and SPF 30+ in the morning. Use this routine consistently for three to four weeks before adding anything else. Next, consider one targeted treatment based on your primary concern — vitamin C for brightening, retinol for anti-aging, or BHA for acne. Add one product at a time with at least two weeks between additions so you can identify what helps or causes problems.
