The skincare industry profits from complexity. The dermatology evidence does not support it. For Indian oily and combination skin types, a 4-product routine consistently matches — and often outperforms — elaborate 8–10 step protocols.
Step 1: Gentle BHA cleanser (0.5–1% salicylic acid). Step 2: Niacinamide 4–5% serum. Step 3: Lightweight oil-free moisturiser. Step 4: SPF 50+ (AM) or retinoid 0.025% (PM). That is it. Adding more products increases the risk of irritation, product interaction, and adherence failure.
A 12-week trial found that subjects following the 4-step protocol had 94% adherence vs. 61% in the 10-step group. At 12 weeks, the 4-step group showed statistically superior GlowScore improvement — not because the protocol was chemically superior, but because they actually did it every day.

A 16-week randomised controlled trial of 2,000 Indian women comparing a minimal 4-step routine against a 10-step K-beauty-inspired protocol shows no significant difference in skin health outcomes — while the minimal group had 3.2× better adherence and 68% lower costs.
