What order should a simple skin routine follow?
Use cleanser, treatment, moisturizer, then sunscreen in the morning. At night, skip sunscreen and add only one new active at a time.
Retinol Routine
Five practical starting points, with safety limits and source links.
How should you patch test a new beauty product?
Test a small area as directed, repeat before wider use, and stop for persistent burning, swelling, blistering, or worsening irritation.
Fragrance-free vs unscented: what is the difference?
Fragrance-free generally means no fragrance ingredients were added for scent. Unscented products may still use ingredients to mask odor. Check the ingredient list.
How long should you test a new routine?
Keep the base routine stable and change one item at a time. The safe trial length depends on the product, label, goal, and whether irritation occurs.
When should a skin concern see a dermatologist?
Seek care for severe pain, infection signs, scarring, sudden changes, major distress, or a problem that persists despite a simple routine.
When should you stop using a skin care product?
Stop a new skin care product when it causes persistent burning, swelling, blistering, hives, or worsening irritation. Wash it off, avoid adding more new products, and seek medical care for severe or spreading symptoms.
