Glow sunscreen SPF 50, In-Vivo Tested with PA++++

Foxtale's Golden Hour Glow Sunscreen SPF 50 PA++++ is an in vivo-tested, broad-spectrum sunscreen built around a 100% new-generation UV filter system and layered with Vitamin C + Niacinamide. Designed for all skin types– and equally suited as a sunscreen for men and a sunscreen for women– the formula fits easily into a daily sunscreen routine while delivering reliable UV protection. Explore Foxtale's sunscreen collection for more SPF options suited to different skin types and finishes. 
The lightweight, non-comedogenic formula absorbs quickly into a non-greasy, non-sticky finish with no white cast, so it layers cleanly under makeup and holds up through sweating on high-heat, high-activity days. For oily or acne-prone skin, choosing a lightweight formula can make daily sunscreen application easier. Explore Foxtale's sunscreen for oily skin collection for lightweight SPF options. Unlike sunscreens that rely on filter percentages alone, every claim here is backed by in vivo and in-vitro lab testing, not just an SPF number on the tube.

SPF and PA measure different aspects of sunscreen protection. If you're unsure how SPF levels compare, read our guide to [SPF 50 vs SPF 30] and what the difference means for everyday sun protection. SPF primarily measures protection against UVB-induced erythema, while the PA system indicates UVA protection. A broad-spectrum sunscreen is designed to protect both UVA and UVB wavelengths.

Golden Hour Glow Sunscreen achieved an in-vivo SPF of 55.176 under ISO 24444:2019 testing and PA++++ under ISO 24442:2019 testing. Its in-vitro testing also recorded an SPF of 60+ and PA++++, while independent testing recorded an SPF of 63.04.
 

Sunscreen protection depends on more than a single SPF value. SPF primarily reflects protection against UVB-induced erythema, while UVA protection is assessed separately through measures such as the PA rating and UVA protection factor. Golden Hour Glow Sunscreen was evaluated through in-vivo and in-vitro SPF and PA testing, along with independent SPF verification, to assess its protection across UVA and UVB wavelengths.

Golden Hour Glow Sunscreen: SPF, PA & Broad-Spectrum Test Results 

Photostability describes how well a sunscreen maintains the performance of its UV-filter system when exposed to UV radiation. A photostable formulation is important because UV exposure can affect the performance of some UV filters over time. Golden Hour Glow Sunscreen underwent photostability testing under controlled UV exposure, with SPF, UVAPF and spectral absorbance assessed at defined intervals.

Photostability Claim Sheet conclusion (Centre for Cruelty Free Testing, Project No. CCFT-2025-12-H2592): "Based on the above results, it is concluded that the test sample, Foxtale Golden Hour Glow Sunscreen, is photostable." 

What Makes Golden Hour Glow Sunscreen's UV Filter System Photostable?

Golden Hour Glow Sunscreen uses a combination of modern organic UV filters, including Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB), Ethylhexyl Triazone, and Tris-Biphenyl Triazine. These filters provide complementary UVA and UVB absorption and are selected for their photostability characteristics. To understand how organic UV filters differ from mineral filters, read our guide to [chemical vs mineral sunscreen].

The glow of Golden Hour Glow Sunscreen comes from the overall formulation and its finished skin feel, rather than from UV protection alone. The formula combines its UV-filter system with skincare ingredients including Ethyl Ascorbic Acid, Niacinamide and Tocopherol, while its lightweight texture is designed to spread evenly across the skin without leaving a visible white cast.
The result is a radiant-looking finish that can be worn on its own or underneath makeup. This cosmetic glow should be distinguished from longer-term changes in skin appearance associated with consistent skincare and sun protection.

UV exposure can generate oxidative stress in the skin. In addition to its UV-filter system, Golden Hour Glow Sunscreen contains Ethyl Ascorbic Acid, Niacinamide and Tocopherol (Vitamin E) to provide antioxidant and skin-supporting benefits alongside daily UV protection.

1. Niacinamide: Niacinamide is a form of Vitamin B3 that supports the skin barrier and helps maintain skin resilience. Learn more about [niacinamide and skin barrier support]. 
2. Ethyl Ascorbic Acid (a stable Vitamin C derivative): Ethyl Ascorbic Acid is a stable Vitamin C derivative that provides antioxidant support and is used in the formula to support brighter-looking skin. Learn more about [Vitamin C for pigmentation and uneven skin tone] and its role in a broader skincare routine. 
3. Tocopherol (Vitamin E): Tocopherol, or Vitamin E, is an antioxidant that helps support the formula's antioxidant system while contributing to skin conditioning. 

These ingredients complement rather than replace the sunscreen's UV-filter system. Read: [Vitamin C sunscreen benefits] to understand how antioxidant ingredients complement UV protection. The primary source of UV protection remains the product's UV-filter system and its tested SPF/PA performance.
 

1. Cleanse with a gentle, pH-balanced face cleanser. Pat the skin dry rather than rubbing with a towel.
2. Apply an adequate amount evenly across the face and neck to create a uniform layer of sunscreen. For more detail, read [how much sunscreen you should apply] for the face and neck. 
   - Massage evenly across the face and neck in upward strokes. 
   - Allow the sunscreen to settle before applying makeup or other products.
   - Reapply during prolonged outdoor exposure, particularly after heavy sweating, swimming, washing, or towel drying.
3. Reapply every 3–4 hours if you're outdoors for extended periods — especially if you're sweating heavily — since even a photostable, broad-spectrum sunscreen loses some protective capacity over continuous sun exposure (see photostability data above).
4. For best results as a sunscreen for glowing skin, apply as the last step of your morning routine, after moisturizer and before makeup. Because the formula is lightweight and non-greasy, it is designed for comfortable daily use under makeup or on bare skin.

Most sunscreen conversations stop at the SPF number. Foxtale's approach to formulating a broad-spectrum sunscreen is built on four non-negotiables: 

Golden Hour Glow Sunscreen was evaluated through: 
1. In-Vivo SPF & PA Testing — CCFT Laboratories (ISO 24444:2019, ISO 24442:2019), CTRI Registration No. CTRI/2025/12/099152 
2. In-Vitro SPF, PA & Broad Spectrum Testing — CCFT Laboratories (COLIPA Guideline) 
3. Independent SPF Verification — Mascot Spincontrol Clinical Research Centres (Study Code MSI/SPF/23-24/01733) 
4. Photostability Testing — Centre for Cruelty Free Testing / Mittal Global Clinical Trial Services (Project No. CCFT-2025-12-H2592) 

All testing was conducted at ISO 9001:2015, ISO 45001:2015, OECD GLP-compliant facilities, and the CCFT lab operates as a FIST Centre under India's Department of Science & Technology.
