T-Zone

U-Zone

Key Traits

Characteristics You have both dry patches and an

oily T-zone.

Pros You will be the de facto skin guru of your friend

group! Combination skin means you’ll learn the full

range of skin products out there. (Yeah, we know, it’s

a cop-out answer . . . )

Cons It is really, really hard to find a one-and-done

solution that meets both your dry- and oily-skin

needs. Get used to spot-treating dry patches.

Eczema, Psoriasis, and Rosacea

We won’t cover these conditions too much in this book, as they really need to

be diagnosed and treated by a qualified dermatologist. In a nutshell, all three

are common skin conditions characterized by compromised stratum corneum

function, which makes it a lot easier for outside allergens to get into your skin

and cause irritation. Here are a couple of things we’ve learned along the way in

our chemist careers that might be helpful:

1. Petrolatum: Also known as petroleum jelly. It’s your friend. It’s the gold-

standard occlusive that can protect your aggravated skin from the elements.

2. Skin-friendly pH: Normal skin pH sits at a slightly acidic 5.5. Many people

with SC conditions like eczema and rosacea have skin pH that skews higher.

For people with these conditions, we recommend checking the pH of your

cleanser, shampoo, and body wash to help with long-term management.

Ultimately, if you have any of these conditions, it’s best to start routine

building with a dermatologist’s everyday guidance. In more serious cases,

prescription topicals might be necessary. In these cases, think of skincare more

as support products rather than key problem-solvers.
