Sunscreen products are commercially available items found in various stores. They are specifically designed to protect your skin from the harmful effects of the sun’s rays. These products come in various forms, such as creams, gels, or sprays. They provide protection through the use of special cosmetic ingredients known as UV filters.
UV filters are special ingredients in sunscreen products that are designed to protect your skin from the harmful effects of the sun’s rays. They are divided into two main categories: organic and inorganic (also known as mineral) UV filters. Inorganic UV filters act like a protective shield on your skin. They reflect a small portion of the incoming radiation—much like a mirror—and absorb the majority of it. Their protective effect depends on the wavelength of the incoming UV radiation. UVA radiation is primarily reflected, while UVB radiation is predominantly absorbed by mineral UV filters. Organic UV filters, on the other hand, use their unique molecular structure to absorb UV radiation and convert it into harmless chemical energy. In this way, the UV radiation is neutralized and the skin is protected. To ensure a broad spectrum of protection, a combination of different UV filters is necessary. This is because each UV filter covers only a specific range of radiation that it can block.
UV radiation, a component of sunlight that reaches us on the Earth’s surface, plays a crucial role in our skin health. “UV” stands for “ultraviolet” and refers to a specific wavelength range of radiation. UV radiation is further divided into three categories: UVA, UVB, and UVC. UVA and UVB radiation are the two types that reach us on Earth and have a significant impact on our skin health. Therefore, they are of particular importance in the cosmetics industry. UVC radiation, on the other hand, does not reach the Earth’s surface and is therefore irrelevant for cosmetic purposes.
The sun protection factor (SPF), an essential component of every sunscreen product, is a key indicator of the level of protection a product provides against UV-B radiation.
The numbers that represent the sun protection factor vary and can be, for example, 20, 30, 50, or even 50+. These numbers are the result of precise testing and indicate how much the product extends the duration of sun protection, thereby keeping the skin protected from sunburn for longer.
To explain this in more detail: The sun protection factor (SPF) is determined by measuring the minimal erythemal dose (MED). The MED is the amount of UV-B radiation required to cause minimal skin redness (erythema).
There are many myths surrounding SPF and sun protection in general.
A day cream with SPF is one of the most important anti-aging essentials today. That’s because UV radiation is one of the main drivers of premature skin aging—regardless of the season or weather. What many people underestimate is that not only UVA and UVB rays, but also blue light and infrared radiation affect the skin on a daily basis and accelerate processes such as wrinkle formation, loss of elasticity, and changes in pigmentation.
This is exactly where DOC BERGER EFFECT’s Four Seasons Day Cream with SPF 50+ comes in—and it goes far beyond traditional day creams with sun protection.
A sun protection factor of 50+ is considered the gold standard for daily protection against UV-induced skin aging. At the same time, many sunscreen products have come under criticism because they rely on UV filters that can be problematic for sensitive skin or are not very aesthetically pleasing. The Four Seasons Day Cream demonstrates that high protection and high skin tolerance do not have to be mutually exclusive.
The formula combines modern, photostable UV filters with antioxidant-rich ingredients and consistently avoids unnecessary or irritating additives. The result is reliable, broad-spectrum protection that feels comfortable on the skin and can be easily incorporated into your daily skincare routine.
What makes the Four Seasons Day Cream special is its holistic approach to protection. In addition to high UV protection, it also offers enhanced protection against blue light and infrared radiation—two environmental factors that are becoming increasingly significant in our digital lives and due to environmental pollution. This protects the skin not only from the sun’s rays but also from invisible stressors that contribute to skin aging over the long term.
Despite its high SPF, the Four Seasons Day Cream is not a traditional “sunscreen,” but rather a full-fledged anti-aging day cream. Plant-based squalane, panthenol, and aloe vera strengthen the skin barrier and support regeneration. Various forms of hyaluronic acid intensely hydrate the skin and leave it feeling smooth and plump. Green tea and other antioxidant plant extracts help protect the skin from oxidative stress.
This combination makes the cream ideal for anyone who wants not only to protect their skin but also to actively care for it and keep it healthy in the long term.
The name says it all: Four Seasons Day Cream was developed to care for your skin all year round—in summer as well as in winter, in everyday life as well as on vacation. It protects, nourishes, and supports your skin in every situation, without feeling heavy or leaving a white film.
This makes it more than just a day cream with sunscreen. It is a key component of modern anti-aging skincare —for anyone who wants to combine consistent UV protection, clean beauty standards, and noticeable skincare benefits in a single product.
It's important to use sunscreen correctly to ensure the best possible protection. Here are a few tips:
