A pairing view of common actives: which combinations are safe and which should be separated.
Niacinamide at 2% to 5% is well tolerated and pairs safely with most other active ingredients. It can sit in the same routine as retinol, vitamin C and AHAs without needing separation.
Vitamin C at 10% to 20% belongs in the morning. As an antioxidant it works alongside daily broad-spectrum sunscreen, which is the single most effective anti-ageing measure because UV exposure drives most visible skin ageing.
Retinol belongs in the evening and is best introduced two or three nights per week, increased gradually to limit irritation. Keeping it opposite vitamin C in the day avoids stacking two potentially irritating steps in one application.

AHAs and retinol both raise cell turnover. Used on the same night they tend to produce the flaking and stinging that makes people quit; alternating them across the week keeps the routine tolerable.
Sunscreen dose is the constant: tested at 2 mg per square centimetre of skin, roughly half a teaspoon for the face alone, regardless of which actives are in the routine underneath it. SPF 30 blocks about 97% of UVB and SPF 50 about 98%.
The practical rule: one exfoliating or retinoid step per evening, niacinamide alongside anything, vitamin C in the morning, sunscreen every day.
