We didn't just wing it. Every formula carries Dr. G's official stamp of approval, a board-certified dermatologist who's seen firsthand what happens when guys skip SPF.

THE 4-SKIN DIFFERENCE

Most guys don't read labels. We get it. But ingredients matter. So we built 4-Skin with the ones that actually do something, and left out everything that doesn't.

Think of it as the good parts of your girlfriend's fancy skincare routine without the perfume, glitter, or 10-step process. Dermatologist-formulated, because Arturo's already had one Mohs surgery and that was plenty.

Broad-spectrum SPF 50 for great protection.

Niacinamide and Hyaluronic Acid — dermatologist-recommended for healthier, younger-looking skin and lasting hydration.

Lightweight, fast aborbing, feels like nothing.

No greasy residue, no shine, no white cast.

Free of parabens, oxybenzone, avobenzone, octinoxate, and fragrance — because what's not in it matters almost as much as what is.

We Put the Good Sh*t In

Active ingredients & concentration:

zinc oxide 9.0%, octocrylene 7.5%

Ingredient insights:

the overachiever

Niacinamide (Vitamin B3): Strengthens your skin barrier, evens out skin tone, minimizes pores, and makes you look like you actually get 8 hours of sleep. You don't. It doesn't matter.

the hydration magnet

Sodium Hyaluronate (Hyaluronic Acid): Pulls moisture into your skin and keeps it there so your face stays smooth and done with its dry era.

the mineral bodyguard

Zinc Oxide: Sits on top of the skin and reflects UVA and UVB rays before they can do damage.

the closer

Octocrylene: Absorbs UVB rays (the ones that burn), stabilizes the formula, and makes it feel like it's not even there.
