Thirty Seconds. After Every Wash.

🧼

Wash First

Always apply serum to a clean face. Use The Wash first then pat dry.

💧

Apply The Serum

Take a pea-sized amount and tap it gently onto your face and neck using your fingertips.

✅

Done

No need to rinse. Let it absorb. Takes about 30 seconds. That is the whole step.

Get More. Spend Less.

The Serum works great alone. It works even better paired with The Wash. Get both for $44.99 and save $10.

Guys Who Made The Switch.

My skin used to be shiny all day. Started using this after washing and the difference after two weeks was actually noticeable.

I was skeptical about serums but this one is not greasy at all. Goes on clean and my pores look smaller.

Redness is down, breakouts are down. I use it every morning after washing and it takes like 20 seconds.

Quick Answers.

After washing your face. Apply to clean dry skin morning and night.
No. The formula absorbs quickly and leaves your skin feeling balanced not oily or heavy.
Most guys notice less shine and smaller looking pores within two to four weeks of consistent use.
Yes — that is the whole point. The Wash cleans, The Serum treats. Two steps, sixty seconds, done.

For external use only. Avoid contact with eyes. If irritation occurs discontinue use immediately. Keep out of reach of children. Store in a cool dry place.
