A calm, four-step OneSkin routine for sensitive skin: cleanse, treat, moisturize, and protect with fragrance-free, barrier-friendly formulas.

Quick answer

Keep it to four steps: a gentle cleanse, one peptide treatment, a barrier moisturizer, and a mineral SPF in the morning. For sensitive skin, introduce one new product at a time and patch test before adding the next.

Why sensitive skin needs a shorter routine

Every extra step adds another chance for a reaction. A minimal routine makes it easier to spot which product helps and which one stings. It also reduces the chance of layering ingredients that don't agree with each other.

The four-step order that works

Cleanse, treat, moisturize, protect. That order moves from thinnest to thickest and keeps your barrier covered. If you use a serum, apply it to slightly damp skin; if you use a cream, press it in rather than rubbing.

How to introduce each step without a flare-up

Start with the cleanser for three to four days. If your skin stays calm, add the treatment every other night for a week. Then add moisturizer, then SPF. If anything burns or itches, stop that product and go back to the last step that felt fine.

Your four-step sensitive skin routine

Step 1: Cleanse gently: Use a fragrance-free cleanser with lukewarm water. Massage with fingertips for about 20 seconds, then rinse. Common mistake: scrubbing with a cloth or hot water, which strips the barrier before you've applied anything helpful. Checkpoint: skin should feel soft, not tight or squeaky.
Step 2: Apply one peptide treatment: Pat a pea-sized amount of your OS-01 treatment onto damp skin, avoiding the eyelids and any broken areas. Common mistake: layering multiple actives at once, which makes it impossible to tell what's causing irritation. Checkpoint: start every other night for the first week.
Step 3: Seal with a barrier moisturizer: Press a fragrance-free moisturizer over the treatment while skin is still slightly damp. Common mistake: waiting until skin is fully dry, which reduces absorption and leaves a tight feeling. Checkpoint: if you still feel dry after 10 minutes, add a second thin layer.
Step 4: Protect every morning: Finish your morning routine with a mineral SPF 30 or higher, like OS-01 FACE SPF. Use two finger-lengths for the face and neck. Common mistake: skipping SPF on cloudy days or indoors near windows. Checkpoint: reapply every two hours if you're outside or near a window.
