What Is the Recommended SPF Level for Daily Use? A Manufacturer’s Guide to Anti-Aging Defense

Introduction
In the fight against premature aging, sunscreen is the most effective weapon available. Yet, the shelves are crowded with numbers ranging from 15 to 100. Consumers and brand owners alike often struggle with the core question: "What is the recommended SPF level for daily use?" Is higher always better?

At Guangzhou Rysun Biotechnology, we view sun care as a health necessity, not just a cosmetic choice. Founded in 2014 by Ivy Wong to combat the "inconsistent quality" of market products, and inspired by deep discussions with a Swiss anti-aging expert, we know that 90% of skin aging is caused by the sun. Therefore, the "daily" SPF you choose determines how your skin will age.

Backed by our Research Institute and 20 leading scientists, we are here to demystify the numbers. Here is the scientific verdict on the ideal SPF level and how Rysun manufactures products that make daily compliance easy.

The Short Answer: The "Goldilocks" Zone (SPF 30 to 50)

To answer "what is the recommended SPF level for daily use?", the global consensus among dermatologists and our R&D team is SPF 30 to SPF 50.

• SPF 30: Blocks 97% of UVB rays. Ideal for office workers, incidental exposure, and cloudy days.
• SPF 50: Blocks 98% of UVB rays. Ideal for outdoor activities, fair skin, or those using photosensitizing actives like Retinol.

Why not higher?
The jump to SPF 100 only offers 99% protection (a 1% increase). However, achieving SPF 100 requires significantly more chemical filters, often leading to a heavy, greasy texture. Rysun focuses on SPF 30-50 as the "Practical Solution"—high protection with a texture people actually enjoy wearing.

The "Daily" Factor: It Must Be Broad Spectrum

The SPF number only tells you about UVB (Burning). For daily use, the goal is anti-aging.

• The Threat: UVA rays (Aging rays) penetrate glass and clouds. They destroy collagen deep in the dermis.
• The Rysun Standard: Inspired by our Swiss anti-aging heritage, we refuse to manufacture high-SPF products that ignore UVA. We formulate to meet high PA ratings (PA+++ or ++++), ensuring that your daily SPF protects against wrinkles, not just sunburn.

The Manufacturer’s Secret: Stability Over Numbers

If you ask "what is the recommended SPF level?", we will tell you: The one that stays on your face.
A cheap SPF 50 that breaks down in sunlight is less effective than a stable SPF 30.

How Rysun Ensures Daily Protection:

• Photostability: Sunscreen filters can degrade when hit by UV light. Leveraging our 253 intellectual properties, Rysun uses advanced encapsulation and stabilizing agents to ensure the SPF value remains constant throughout the day.
• Film-Forming Technology: For daily use under makeup, the product must set effectively. Our Research Institute engineers "invisible films" that lock the filters onto the skin without pilling or feeling sticky.
• Strict QC: We implement 50 inspection procedures. We test our sunscreens under rigorous conditions to verify that the SPF 30 or 50 on the label is exactly what is in the bottle.

Choosing the Right Texture for Daily Use

Compliance is key. The recommended SPF is the one you will actually wear.

• For Oily Skin: We manufacture lightweight, water-based SPF 30 gels using our 105 product patterns.
• For Dry Skin: We create moisturizing SPF 50 creams enriched with Ceramides and Hyaluronic Acid.

FAQs

Q1: Is SPF 15 enough if it's in my foundation?
A: Generally, no. People rarely apply enough makeup to reach the tested SPF level. Rysun recommends applying a dedicated SPF 30 sunscreen under makeup to ensure full coverage.

Q2: Does SPF 50 last longer than SPF 30?
A: No. The number indicates the strength of filtration, not the duration. Both degrade over time. Rysun advises reapplication every 2 hours if outdoors, or using a mineral powder touch-up for office days.

Q3: Can I use the same SPF for face and body daily?
A: You can, but facial skin is more sensitive. Rysun manufactures specialized facial sunscreens that are non-comedogenic (won't clog pores) and lightweight, whereas body formulas are often heavier.

Q4: Does Rysun verify the SPF rating?
A: Yes. We coordinate independent in-vivo (human) and in-vitro (lab) testing to legally validate the SPF claim on your packaging, ensuring your brand meets global regulatory standards.
