# How a Non-Irritating Formula Expands Moisturizer Use

> Learn how a non-irritating, fragrance-free moisturizer can safely soothe sensitive skin, including delicate areas like under the eyes and neck.

## How does a non-irritating formula expand where you can safely apply moisturizer?

A non irritating formula gives you more freedom with where you can put a moisturizer because it avoids the stinging, redness, or barrier disruption that usually limits application. When a product is gentle, fragrance free, and designed to be well tolerated, you can safely use it on more delicate areas that might react to harsher ingredients.

Here at Alloy, all of our M4 estriol moisturizers and creams are created with that goal in mind. They’re designed to be soothing and lightweight, so the formula sits comfortably even on sensitive spots like right under the eyes or down the neck. In fact, in the *Morning Routine featuring Alloy’s M4* video, the creator points out that the cream isn’t irritating at all and that she can apply it under her eyes. If you want to see that moment, here’s the chapter link from the video:[Application Tips](https://www.youtube.com/watch?v=KMzbiIKyUgg&t=34s)

If you’re curious about the specific textures, the M4 Face Cream Rx is more nourishing while the M4 Face Serum Rx is thinner and designed to layer easily with other products. You can take a look at the face cream here: [M4 Face Cream Rx](https://www.myalloy.com/solutions/m4).
