• Barrier protection: Layer products for extra protection against wind and cold 

Summer Modifications:

A: Air travel creates unique challenges for our concentrated formulas: 

Pre-flight Preparation: 

• Apply extra 4D Hyaluronic Acid serum before boarding

During Flight:

• Use snail mucin mask post-flight for recovery 

Post-flight Recovery: 

• Intensive hydration routine upon arrival

Retinol Purging (Normal): 

• Occurs in areas where you normally break out 

• Happens with 3% retinol during first 4-8 weeks 

• Breakouts come to surface faster but heal quicker 

• Gradual improvement over time 

True Allergic Reaction: 

• Breakouts in areas where you don’t normally have acne 

• Accompanied by redness, swelling, or severe irritation 

• Worsens over time rather than improving 

Action Steps: 

• Stop immediately if suspected allergic reaction 

• Reduce frequency for purging (use 3% retinol once weekly) 

• Use pimple patches on active breakouts 

• Introduce one product at a time to identify triggers 

• Contact your health care provider or dermatologist if problems persist beyond 6 weeks 

A: Watch for these warning signs:

Immediate Symptoms:

• Burning or stinging within minutes of application
• Severe redness or flushing
• Immediate swelling or hives

Delayed Reactions:

• Rash or hives appearing within 24-48 hours
• Persistent swelling or puffiness
• Skin that feels hot or inflamed

Action Steps:

• Stop use immediately and rinse with cool water
• Apply cool compress to affected areas
• Take antihistamine if experiencing systemic reaction
• Contact healthcare provider for severe reactions
• Initiate return through your retailer (Amazon, etc.)
• Send us your comments regarding your experience to support@sigmaessentialsusa.com

A: Pilling usually indicates application or compatibility issues: 

Common Causes: 

• Over-application: Using too much of our rich, concentrated formulas 

• Insufficient absorption time: Not waiting between product layers 

• Incompatible layering: Mixing silicone and water-based products incorrectly 

• Skin preparation: Applying to skin that isn’t completely clean or dry 

Solutions:
