WHAT TO EXPECT
Science takes time—results do, too
There’s no such thing as overnight results. Here’s what you can expect from the TSOS™ system.

What to Expect
Month 1
We use clinically proven ingredients—
for some, results may begin in as little as two weeks: Less dryness and irritation, more hydration and comfort. Customers call it The TSOS™ Glow.

What to Expect
Month 2
Ceramides are replenishing the skin barrier: Dullness brightens, hyperpigmentation lightens, fine lines and wrinkles soften. You look refreshed—your skin is getting stronger by the week.

What to Expect
Month 3+
You start to see the benefits of our anti-aging peptides: Age spots and wrinkles look less noticeable, and you look more revitalized. Skin is becoming less reactive and more resilient.
Real skin, real relief

FREQUENTLY ASKED QUESTIONS
The skin barrier is your skin’s protective outer layer. It functions to keep moisture in and irritants out. When it’s healthy and functional, skin feels hydrated, calm, and comfortable—but when it’s dysfunctional, skin feels dry, tight, and irritated.
Barrier-disrupted skin is simply skin whose protective outer layer isn’t functioning optimally. Barrier dysfunction can be caused by harsh cleansers and exfoliators, cleansing with hot water, extreme heat or cold (like our Canadian winters), or too many actives.
Barrier-disrupted skin is less hydrated and more sensitive and reactive: Think dull, dry, tight, irritated, red, stinging or burning, itchy, or flaky. If skincare products don’t work on your symptoms, it’s probably your skin barrier, not just “sensitive skin.”
Sensitive skin is reactive: It gets irritated easily, but the cause can vary. Barrier dysfunction is one of the most common causes of sensitive skin.
TSOS™ is a complete barrier-first AM/PM skincare system: Two serums, two treatments, and two moisturizers. Each formula is made with our proprietary barrier-first blend, Triome™, and formulated with different active ingredients to target common skincare concerns.
No. The system was designed to be simple, intentional, and complete, so you never have to try another skincare serum, treatment, or moisturizer again. But if your skincare routine is working for you, you can layer in only the TSOS™ formulas your skin needs.
We formulated the TSOS™ system with ingredients clinically proven to show visible results within 14 days. For best results, continue using TSOS™ formulas daily for at least three months.
