## What reviewers say

Based on a very large amount of data, users describe this serum as a daily essential that brightens dull complexions and provides lightweight hydration, often creating a healthy glow and fading acne scars. While the scent is frequently praised, some users find the results for fine lines inconsistent, and a small number of sensitive skin types report irritation due to the citrus formulation.

- Liked: Uplifting citrus scent (mostly mentioned)
- Liked: Brightens and evens tone (often mentioned)
- Liked: Lightweight and absorbing (often mentioned)
- Disliked: Expensive price point (often mentioned)
- Liked: Hydrates and softens (sometimes noted)
- Disliked: Sticky finish (sometimes noted)
- Disliked: Irritation or breakouts (rarely noted)

## 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.
