The FULLY products selected here do not all do the same job. FULLY PORE CLEANSING BRUSH is listed as cleansing, while FULLY: Adlay Niacin Grain Mask (120ml), FULLY GREEN TOMATO ACID 20 WASH OFF PEELING SERUM 50ml, and FULLY GREEN TOMATO CLEANSING OIL 250ml belong to mask or patch, cleansing, and cleansing respectively. That difference matters more than a shared brand identity when you are deciding what to buy first.
Use the product format as the first filter. A cleansing or prep item usually sits earlier than a leave-on serum or cream, and a mask or patch is often an occasional format rather than a replacement for a daily step. The product name offers a starting clue, but the exact directions on the live page remain the deciding source.
When two products use similar ingredient language, do not treat the label as a full formula summary. Compare leave-on versus rinse-off use, application area, product size, and the instructions supplied for that SKU. This keeps the choice practical and avoids duplicating the same role in one routine.
