Creating Sunscreen in the USA: Challenges and Regulations

With the record temperatures and heat waves we're experiencing, sunscreen is no longer optional: it's survival. However, creating an effective sunscreen in the United States is extraordinarily complex and expensive. As a dermatologist, I'll explain why it's so challenging to develop SPF products in the USA and what you should know to choose the best sunscreen.

Why It's So Difficult to Create Sunscreens in the United States

Classification as OTC Medication

In the United States, sunscreens are not simple cosmetics:

Over-the-counter medication: Like Tylenol, Advil, or aspirin
Strict FDA regulation: Total control over ingredients and claims
Complex process: Cannot be created casually and sold
Rigorous standards: Among the strictest in the world

UV Filter Limitations

The biggest limitation is the available filters:

United States vs. Rest of the World

USA: Only 16 UV filters approved by FDA
Practical use: Approximately 8 filters used regularly
Europe/Asia: More than 30 approved filters available
Superior technology: Newer, photostable, and more elegant filters

Innovative Filters Not Available

Filters that the USA doesn't have access to include:

Tinosorb: Latest generation filters
Mexoryl: Superior UVA protection
Uvinul: Advanced protection technology
Years behind: 5-10 years behind global innovation

Entry Barriers for New Filters

Introducing a new UV filter in the USA requires:

Massive investment: Millions of dollars in research
Extensive time: 5-10 years of clinical studies
Corporate resources: Only conglomerates like L'Oreal can afford it
Exhaustive documentation: Safety and efficacy studies

Development and Testing Process

Mandatory Testing

Once the product is formulated, multiple tests are required:

SPF Testing (UVB)

In vivo testing: Performed on real people
Cost: $15,000-$20,000 per test
Multiple rounds: Frequently needed to confirm formula
Strict standards: Specific FDA methodology

Broad Spectrum Testing (UVA)

In vitro testing: Performed in laboratory
Additional cost: $5,000-$10,000
UVA confirmation: Protection against aging
Essential requirement: For "broad spectrum" claims

Water Resistance Testing

Intensive process: Multiple immersions and activities
Cost: $6,000-$10,000
Duration: 40 or 80 minutes of resistance
Specific methodology: Strict FDA protocols

Additional Testing

Stability: Resistance to heat, humidity, and time
Irritation: Patch testing for allergies
Compatibility: Interaction with packaging
Multiple formulations: Repeated testing for optimization

Development Costs

Costs before launch include:

Formula development: $50,000-$100,000
Regulatory testing: $30,000-$50,000
Legal compliance: $10,000-$20,000
Packaging and production: $20,000-$50,000
Total: $100,000-$200,000+ before the first dollar of sales

FDA Regulations and Compliance

Registration and Documentation

After successful testing:

FDA registration: Complete formula submission
Laboratory collaboration: Compliance confirmation
Specific language: Every word must follow FDA terminology
Mandatory labeling: Information panel like medication

Specific Instructions

15-Minute Wait Time

Contrary to popular beliefs:

Not activation: Sunscreen works immediately
Real purpose: Allows it to dry and form a film
Adherence: Creates physical bond with skin
Resistance: Harder to rub off or sweat off

Regulatory Language

All labeling must follow:

FDA terminology: Specific approved words
Permitted claims: Only statements backed by testing
Mandatory information: Drug facts panel
Warnings: Precautions and contraindications

Advantages of the American System

Quality Standards

Despite limitations, American sunscreens offer:

Strict regulations: Among the most rigorous in the world
Proven safety: Exhaustive safety testing
Consistency: Reliable and predictable products
Transparency: Clear information about ingredients and efficacy

Innovation Within Limitations

American manufacturers compensate with:

Advanced formulations: Smart combinations of existing filters
Improved textures: Better user experience
Additional ingredients: Skin care benefits
Application technology: Better dispensing systems

Characteristics of an Effective Sunscreen

Essential Protection

A good sunscreen should offer:

UVA/UVB Protection

SPF 30 minimum: Adequate basic protection
SPF 50 recommended: Superior protection
Broad spectrum: UVA and UVB coverage
Water resistance: 40-80 minutes as needed

Effective Filters

Common combinations in the USA:

Avobenzone: Broad spectrum UVA protection
Homosalate: Stable UVB filter
Octocrilene: Stabilizer and UVB filter
Octisalate: Additional UVB filter

Additional Benefits

Skin Care Ingredients

Antioxidants: Protection against free radicals
Moisturizers: Keep skin soft
Anti-inflammatories: Reduce irritation
Active ingredients: Treatment of specific problems

Texture Characteristics

Quick absorption: Doesn't leave greasy residue
No white cast: Transparent on all skin tones
Long-lasting hydration: Keeps skin comfortable
Compatibility: Works under and over makeup

Innovative Ingredients in Sunscreens

Hexylresorcinol

A standout ingredient for:

Pigmentation reduction: Helps fade spots
Anti-inflammatory properties: Soothes irritated skin
Brightening: Improves overall skin tone
Comparable efficacy: Similar to 2% hydroquinone

Moisturizing Ingredients

Squalane

Light hydration: Doesn't clog pores
Quick absorption: Non-greasy texture
Compatibility: Works with all skin types
Stability: Maintains efficacy over time

Ceramide Complex

Barrier protection: Strengthens skin barrier function
Moisture retention: Maintains natural hydration
Repair: Helps restore damaged skin
Prevention: Reduces transepidermal water loss

Proper Sunscreen Application

Adequate Amount

For effective protection:

Face and neck: 1/4 teaspoon (1.25ml)
Full body: 1 ounce (30ml)
Generous application: Don't skimp on quantity
Even distribution: Complete coverage without missing areas

Application Technique

Correct Steps
