The main difference between UVA and UVB rays concerns their wavelength and how they interact with the skin. UVA rays penetrate more deeply, while UVB rays act primarily on the surface. For this reason, for complete and effective protection, it is always recommended to use broad-spectrum sunscreen capable of blocking both.

Understanding these differences allows you to experience tanning more consciously, achieving a beautiful, even, and long-lasting complexion.

🌞 UVA Rays

🔹 Penetration. UVA rays reach the deeper layers of the skin, extending to the dermis.

🔹 Effects. They are primarily responsible for melanin oxidation, the mechanism that gives the skin its typical tanned appearance. If exposure is not properly controlled or is too prolonged, they can promote the appearance of wrinkles, loss of tone and elasticity, and contribute to skin damage.

🔹 Presence. They are present throughout the year, even on cloudy days, and can penetrate through glass.

🌤️ UVB Rays

🔹 Penetration. They primarily affect the outermost layer of the skin, the epidermis.

🔹 Effects. In case of excessive or too intense exposure, they can be the main cause of sunburn and erythema and play a role in the development of skin problems.

🔹 Presence. They are more intense during summer months and midday hours, but are largely blocked by glass.

🌈 Skin Type and Tanning: A Fundamental Connection

Tanning is closely linked to skin type, the classification that describes how the skin reacts to sun exposure. Knowing your skin type is essential for choosing the appropriate exposure times and protection.

🌈 The Main Skin Types

🔹 Skin Type 1. Extremely fair skin, light eyes and hair. Always burns and does not tan. Requires very high protection (SPF 50+) and extremely controlled exposure.

🔹 Skin Type 2. Fair skin, blonde or light brown hair, light or medium eyes. Burns easily and develops only a light, gradual tan.

🔹 Skin Type 3. Fair to olive skin. Tans progressively and burns less than fairer skin types. One of the most balanced skin types.

🔹 Skin Type 4. Olive skin. Tans quickly and evenly, with a low probability of sunburn.

🔹 Skin Type 5. Dark skin. Tans very easily and achieves intense tones. Redness and erythema are rare.

🔹 Skin Type 6. Skin of African origin. Tans deeply and is naturally more protected, but still requires adequate protection to prevent potential damage.
