## What reviewers say

Users with acne-prone and sensitive skin highly praise this serum for its ability to calm redness and soothe inflammation without causing irritation. While the lightweight, watery texture is frequently complimented for layering well, many users note that fading hyperpigmentation (PIE/PIH) is a gradual process requiring consistent long-term use.

## How to apply

- Use this serum in your PM routine. Start by applying it 3 times a week and build up to daily use if your skin tolerates it well.
- Apply the serum after cleansing and toning, but right before your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin. Let it absorb ⏱ for a minute before applying the next product.
- Apply the serum on clean and dry skin since your skin is not sensitive and you want to target oily shine. This helps control excess oil throughout the night.
- Avoid the delicate eye area and do a patch test before using the serum for the very first time.

### Where does this serum go in a skincare routine for oily skin?

This treatment serum goes in the evening routine after cleansing and toning, and before moisturizing. Putting it in the evening helps keep it safe around sun exposure, and you can start using it once a week before slowly increasing the frequency if your skin tolerates it well.

### Can I use this serum with retinol, and in what order?

You can use this treatment with retinol by applying the serum first, letting it absorb, and then following with your retinol on separate nights or spaced out if your skin is sensitive. This helps avoid potential irritation while still managing oily shine and supporting skin repair.

Use this serum in your evening routine, starting once a week and moving to more often if your skin handles it well. Azelaic acid and niacinamide help control oily shine and pores safely.

### Can this serum clog pores, cause breakouts or purging for oily skin?
