Hopscotch Reviews: La Roche-Posay Anthelios UVMune 400 Invisible Fluid SPF50+

The significance of skin care is growing in our daily routines. But one rule holds true—no matter how many fancy serums, moisturizers or toners you slather yourself with, if you do not use an appropriate sunscreen, your whole skincare routine is pointless. In fact, the greatest enemy of our skin is none other than the ultraviolet (UV) rays emitted by the sun. They go deep in the dermis, break collagen apart, and cause hyperpigmentation leading to premature ageing and wrinkle generation.

In the world of skin care, nothing beats sunscreen. But with thousands of brands on the store shelves, it can quickly become a task in business decision making. Well, there is one sunscreen currently reigning supreme across the globe among dermatologists and skincare experts alike: La Roche-Posay Anthelios UVMune 400 Invisible Fluid SPF50+. In this extensive review, we are going to take a closer look at its ingredients, scientific technology, pros and cons, and application techniques.

Category: Scientific Skin Damage caused by UV rays.

Let us first see how UV radiation from the sun affects our skin in order to understand why sunscreen is a must. There are two main types of rays that the sun gives off which causes damage, including UVB and UVA.

UVB Rays (290nm — 320nm): These rays effects our outermost layer of skin(Epidermis). This is mostly responsible for burning the skin, also known as sunburn.

UVA rays (320nm — 400 nm): These rays are much more damaging. They go deep inside the skin (Dermis), destroying collagen and elastin fibers. This leads to aging, fine lines, wrinkles additionally dark spots much sooner than required.

Conventional sunscreens only protect against radiation up to a wavelength of 380nm. On the contrary, almost 30% of solar UVA radiation is in Ultra Long-UVA (380nm – 400nm). These longest wavelengths penetrate deeper, and increase the risk of long-term skin damage and skin cancer. UVMune 400 technology from La Roche-Posay was specifically formulated to help find and capture this long-tested but still elusive, deep penetrating Ultra Long-UVA range.
