How should I store skincare products properly?

Immediate Answer: Store in cool, dark places (15-25°C ideal). Avoid bathrooms (humidity and heat degrade products). Vitamin C and retinol are particularly sensitive to light and heat. Keep products in original packaging until use.

The Science: Skincare ingredients degrade with:

• Heat: Accelerates chemical breakdown (why bathroom storage is bad—shower steam = heat + humidity)
• Light: Degrades retinol, vitamin C, and other light-sensitive actives
• Air exposure: Oxidation degrades efficacy (why airtight packaging matters)
• Humidity: Promotes bacterial growth, degrades formulations

Proper storage extends product lifespan and maintains efficacy.

Specific storage tips:

• Vitamin C serums: Store in cool, dark place. Airtight, opaque bottles only. Discard if oxidised (turns brown).
• Retinol products: Keep in cool place, airtight bottles, away from light
• All products: Original packaging until opened (provides stability)
• Temperature: Cool room temperature (15-25°C). Not refrigeration unless product explicitly states.

How Nordic Formula Preserves Maximum Active Ingredient Efficacy: Nordic Formula products are packaged specifically for stability:

• Opaque bottles (retinol, vitamin C protection)
• Airtight closures (oxidation prevention)
• Stabilised formulations (longer shelf life)

Store products as they arrive—packaging is optimised for stability.

Pro Tip: Bathroom medicine cabinets are the worst storage location for skincare (heat + humidity + light). Bedroom nightstands or closets are ideal. If you must store in bathrooms, use opaque storage boxes away from sink/shower areas.
