SPF value is a key part of any sun care formulation. It shows how well a product protects the skin from UV radiation. SPF mainly blocks UVB rays, which cause sunburn and skin damage. Higher SPF offers more protection, but the increase becomes smaller with each step. For example, SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks around 98%.

How UVA and UVB protection work together

UVB rays affect the skin’s surface. UVA rays go deeper and cause long-term damage. Both increase the risk of aging and skin cancer. That’s why broad-spectrum UV protection is important. SPF measures UVB protection, while the UVA-PF value shows UVA coverage. Both values help create balanced sun care products.

Choosing the right UV filters

UV filters block or absorb harmful rays. Common ones include zinc oxide and butyl methoxydibenzoylmethane. Choosing the right mix of UV filters supports effective protection. It also helps with texture and safety. Filter selection depends on skin type, use case, and market rules.

What else goes into sunscreen

An effective formula needs more than just UV filters. Other ingredients improve the product’s feel, look, and wear. These include sensory modifiers, emulsion stabilizers, and film-forming agents. Eco-friendly ingredients, vitamin E, aloe vera, and bioengineered actives are now common. They also support transparency and better skin experience.

Product types and uses

Sunscreens come in many personal care products, such as:

- Creams with broad-spectrum UV protection

- Moisturizing butter creams with SPF 30

- Lightweight green sun fluid lotions SPF 50+

- High SPF sunscreen lotions SPF 50+ PA+++*

- Skin barrier sun milk for sensitive skin

Testing and safety steps

Every sunscreen must pass safety and performance tests. These include freeze-thaw cycles, sensory panel feedback, and UV filter stability checks. Good products also show strong pay-off and improved skin feel. Testing supports long-term use and consumer trust.

The future of sun care

The global suncare market is growing fast. Customers want safe, light, and eco-conscious options. Makers now use bio-based ingredients. They use UV-protective packaging. They also use clear labeling. With careful planning and testing, brands can meet these needs with effective sun care formulations.
