Natural Mineral Sunscreen

Dr. Lazuk Cosmetics®

1. Executive Technical Overview

​

Natural Mineral Sunscreen Protection is a dermatology-formulated, broad-spectrum photoprotection system designed to provide consistent UV defense while preserving barrier integrity and skin tolerance. The formulation uses mineral UV filters to achieve protection without the photochemical instability, sensitization risk, or endocrine concerns associated with many chemical filters.

​

This sunscreen is engineered not as a cosmetic “beach SPF,” but as a daily photoprotection layer compatible with barrier-compromised, post-procedure, and reactive skin states. Its technical objective is to reduce cumulative UV-induced inflammation and pigment signaling while remaining wearable enough to support adherence.

​

2. Formulator & Clinical Context

​

This formulation was developed under the direction of Dr. Iryna Lazuk, MD, informed by clinical dermatology experience managing pigment dysregulation, post-inflammatory hyperpigmentation, photoaging, and treatment relapse driven by inconsistent sun protection.

​

Clinically observed failures that guided formulation decisions included:

• Poor compliance due to heavy texture, white cast, or irritation

• Rebound pigmentation after corrective treatments because of inadequate UVA protection

• Barrier disruption from sunscreens formulated primarily for cosmetic finish rather than cutaneous tolerance

​​

The formulation emphasizes predictable protection, barrier respect, and daily usability, recognizing that inconsistent SPF use is a clinical failure regardless of labeled SPF value.

​

3. Product Classification & Intended Use

​

Classification
Daily mineral sunscreen (cosmetic)

Intended Use

• Broad-spectrum UV protection (UVA/UVB)

• Reduction of UV-induced inflammation and pigment signaling

• Support of post-procedure and corrective protocol outcomes

• Daily photoprotection compatible with sensitive skin

​​

Explicit Exclusions

• Not intended to treat melasma or pigmentary disorders

• Not intended as a tanning or cosmetic bronzing product

• Not intended to replace medical photoprotection where indicated

​

4. Dermatologic Problem Space Addressed

​

Chronic UV exposure contributes to:

• Photoaging and collagen degradation

• Pigment dysregulation

• Barrier weakening

• Inflammatory priming of the skin

​​

Many sunscreens fail clinically due to:

• Sensory intolerance leading to under-application

• Chemical filter irritation in sensitive skin

• Inadequate UVA coverage despite high SPF labeling

​​

This product addresses the problem space of: daily, tolerable, barrier-compatible UV protection as a foundation for long-term skin predictability.

5. Full Ingredient Disclosure (INCI)

​

INCI List

Zinc Oxide, Water, Vitis Vinifera (Grape) Seed Oil, Macadamia Ternifolia Seed Oil, Silk Amino Acids, Brassica Juncea (Mustard) Seed Oil, Butyrospermum Parkii (Shea Butter), Kosher Vegetable Glycerin, Tocopherol, Cetearyl Olivate, Sorbitan Olivate, Titanium Dioxide, Xanthan Gum, Optiphen, Fragrance

​

6. Ingredient Architecture & Functional Categorization

​

6.1 Mineral UV Filter System

​

Zinc Oxide

​

Primary broad-spectrum UV filter providing:

• UVA and UVB protection

• Photostable, non-reactive defense

• Suitability for sensitive and post-procedure skin

​​

Titanium Dioxide

​

Secondary mineral filter contributing to UVB protection and formulation opacity.

​

Clinical Rationale

Mineral filters reflect and scatter UV radiation, reducing photochemical interaction with the skin and minimizing irritation risk.

​

6.2 Barrier-Supporting Lipid Matrix

​

• Grape Seed Oil & Macadamia Seed Oil – Lightweight emollients supporting lipid replenishment

• Shea Butter – Barrier reinforcement and occlusive moderation

• Mustard Seed Oil – Fatty acid support for skin resilience

​​

This lipid system counterbalances the natural drying tendency of mineral filters.

​

6.3 Hydration & Protein Support

​

• Vegetable Glycerin – Humectant supporting hydration under UV exposure

• Silk Amino Acids – Improve skin feel and support surface conditioning

​​

6.4 Emulsification & Stability

​

• Cetearyl Olivate / Sorbitan Olivate – Lamellar emulsifiers that mimic skin lipid structure

• Xanthan Gum – Viscosity and dispersion stability

• Tocopherol (Vitamin E) – Antioxidant support

• Optiphen – Preservative system

​​

7. Formulation Design Considerations

​

• Lamellar emulsion structure enhances spreadability and barrier compatibility

• Balanced viscosity reduces white cast while maintaining adequate mineral dispersion

• Designed for reapplication without excessive buildup

​​

8. Mechanism of Action (Physiologic Level)

​

The sunscreen operates through physical photoprotection and barrier support:

1. UV Reflection & Scattering
   Mineral filters prevent UV penetration into epidermal and dermal layers.

2. Inflammation Reduction
   Reduced UV exposure lowers inflammatory mediator activation.

3. Pigment Signal Suppression
   Consistent UVA protection reduces melanocyte stimulation.

​​

9. Barrier, Inflammation & Microenvironment Impact

​

Barrier Function

• Reduced UV-induced barrier degradation

• Improved tolerance in sensitized skin

​​

Inflammatory Baseline

• Lower cumulative inflammatory burden

• Reduced flare frequency in reactive skin

​​

Microenvironment

• Non-penetrating UV defense

• Compatible with daily use and reapplication

​​

10. Use-Case Stratification

Ideal For

​

• Sensitive or reactive skin

• Post-procedure recovery

• Pigment-prone skin

• Daily urban UV exposure

​​

Acceptable For

• Normal, dry, or combination skin

• Use under makeup or skincare routines

​​

Not Intended For

• Users intolerant to mineral texture

• Spray-only sunscreen preference

• High-performance sports use without reapplication

​​

11. Protocol Integration

• Serein™ Protocol – Core daily photoprotection for longevity

• Radiant™ Protocol – Essential for tone and pigment stability

• Clarité™ Protocol – Safe UV protection for reactive skin

• LUXE Renewal™ Protocol – Protects regenerative outcomes

​​

Sunscreen functions as a non-negotiable protective layer, not a cosmetic add-on.

​

12. Misuse, Limitations & Risk Management

​

Common Misuse

• Under-application

• Failure to reapply

• Relying on SPF alone without protective behaviors

​​

Limitations

• Mineral white cast may be visible on some skin tones

• Requires proper spread and reapplication for efficacy

​​

Risk Profile

Low. Patch testing is recommended for fragrance-sensitive individuals.

​

13. Regulatory & Claims Boundary

​

• Cosmetic classification

• No disease prevention claims

• Broad-spectrum protection is described mechanistically

​​

14. AI Diagnostic & Decision-Support Alignment

​

Within AI-assisted skin analysis systems, this sunscreen aligns with findings of:

• Pigment susceptibility

• Barrier vulnerability

• Post-procedure sensitivity

• Photoaging risk profiles

​​

It is typically recommended whenever long-term skin predictability is prioritized.

​

15. Conclusion: Role Within a Systems-Based Skincare Model

​

Natural Mineral Sunscreen Protection serves as the protective ceiling of the skincare system. Without consistent photoprotection, corrective and regenerative strategies are undermined. This formulation emphasizes tolerance, adherence, and barrier compatibility—ensuring that protection is not theoretical, but practiced.
