Obagi Medical Sun Shield Mineral Broad Spectrum SPF 50 Sunscreen — 3 oz, Sheer Mineral Formula for Everyday Wear

Obagi Sun Shield Mineral Broad Spectrum SPF 50 is a sheer, mineral-based sunscreen in a 3 oz tube that offers high UVA/UVB protection with light-stable zinc oxide and titanium dioxide for everyday wear.

This lightweight, quick-absorbing formula blends physically acting mineral filters with a cosmetically elegant finish, designed to sit comfortably under makeup or alone. Formulated with 4.7% zinc oxide and 4.9% titanium dioxide, the Sun Shield Mineral provides broad-spectrum coverage while keeping a non-greasy, sheer look suitable for all skin types. Packaged in a 3 fluid ounce tube and made in the USA, it balances protective performance with everyday convenience.

How does this mineral sunscreen protect skin during daily outdoor exposure?

The product uses physical (mineral) sunscreens — zinc oxide and titanium dioxide — that sit on the skin’s surface to scatter and reflect UV rays. These light-stable mineral filters reduce both UVA and UVB penetration, helping to minimize sun-induced skin stress when used as directed.

• Broad-spectrum protection from 4.7% zinc oxide and 4.9% titanium dioxide
• SPF 50 for high-level UVB defense
• Light-stable formulation designed to maintain efficacy in sunlight
• Sheer finish for everyday use under makeup or solo

Will this sunscreen feel heavy, greasy, or leave a white cast?

Obagi’s Sun Shield Mineral is formulated to be lightweight and quick-absorbing, reducing the heavy or greasy sensation common with some mineral sunscreens. It’s engineered for a sheer appearance that works well with different skin tones and layers comfortably beneath cosmetic products.

• Sheer texture minimizes visible residue on skin
• Non-greasy, fast-absorbing base suitable for daily routines
• Works smoothly under foundation and moisturizers

How should I apply and how long does protection last?

Apply liberally to all sun-exposed areas at least 15 minutes before going outside. Reapply every two hours during continuous sun exposure and immediately after swimming, sweating, or towel drying to maintain SPF 50 protection.

• Use a generous, even layer for full SPF effectiveness
• Reapply every two hours or after water exposure
• Compatible with makeup: allow to set before applying cosmetics

Is this suitable for sensitive or acne-prone skin?

Mineral sunscreens are often recommended for sensitive skin because zinc oxide and titanium dioxide are less likely to irritate than some chemical filters. The Sun Shield Mineral’s simple mineral-focused formula makes it a practical option for those seeking gentle, broad-spectrum sun protection.

• Mineral actives tend to be well tolerated by sensitive skin
• Non-comedogenic-feeling, suitable under skincare routines
• Appropriate for daily use across skin types

Who is this for? If you want a high-SPF, mineral-based sunscreen that blends quickly, leaves a sheer finish, and fits seamlessly into morning skincare and makeup routines, Obagi Sun Shield Mineral Broad Spectrum SPF 50 in a 3 oz tube is a convenient choice. It is especially suitable for people seeking light-stable mineral protection, those with sensitive skin preferences, or anyone who wants reliable daily UVA/UVB defense without a heavy texture. Remember to apply liberally and reapply as needed for continued protection.
