This fit is calculated for the concerns frequently associated with sensitive skin: redness, stinging, and reactions to new products. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for sensitive skin; other serums fit it better.

## Why this fit

- Offers moderate benefits for normal skin with niacinamide and glycerin providing hydration and barrier support, but the inclusion of citrus oils may not directly address your redness and irritation concerns.
- While the product contains soothing ingredients like Chamomilla Recutita Flower Extract and Centella Asiatica Extract, their concentrations may not be sufficient to significantly counteract the potential irritancy from the citrus oils for your sensitive skin.
- The product is generally safe for your sensitive skin due to the absence of harsh ingredients and the presence of soothing components.

## What reviewers say

Users with acne-prone and sensitive skin frequently praise this serum for its lightweight, gel-like texture that effectively soothes inflammation and gradually fades post-acne hyperpigmentation.

- Gently press 2-3 drops of the serum into your skin and wait a minute ⏱ for it to soak in.

## Questions and answers

### How well does Numbuzin Goodbye Blemish work for sensitive skin?

This serum is an average fit for sensitive skin because while it includes soothing and hydrating ingredients, the citrus oils it contains may cause irritation and redness. Treatment products for this skin need effective ingredients that calm redness while posing no risk of irritation and lacking essential oils.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/), [Indian Journal of Pharmaceutical Sciences, 2016](https://pubmed.ncbi.nlm.nih.gov/27168678/)

### Which ingredients make this serum a good fit for sensitive skin?

This serum works for sensitive skin mainly because it includes gentle, hydrating ingredients like glycerin and niacinamide alongside calming plant extracts such as Centella Asiatica. However, because it also contains citrus oils that may trigger irritation, a treatment for this skin type needs higher concentrations of soothing components, strong antioxidants, and zero potential allergens to reliably calm redness without adverse effects.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/), [Indian Journal of Pharmaceutical Sciences, 2016](https://pubmed.ncbi.nlm.nih.gov/27168678/)

### What does Niacinamide do for sensitive skin?

Niacinamide helps calm sensitive skin by strengthening the skin barrier and reducing redness and irritation. It is very well tolerated and may improve overall comfort and resilience with regular use.
Sources: [Cutis, 2005](https://pubmed.ncbi.nlm.nih.gov/16209160/), [Journal of Cosmetic Dermatology, 2004](https://pubmed.ncbi.nlm.nih.gov/17147561/)

### What does Sea Buckthorn Extract do for sensitive skin?

Sea buckthorn extract helps calm sensitive skin by easing irritation and reducing redness. It supports the skin barrier to keep moisture locked in and protect against everyday triggers.
Sources: [Medicina, 2026](https://pubmed.ncbi.nlm.nih.gov/42075548/), [Pakistan Journal of Pharmaceutical Sciences, 2014](https://pubmed.ncbi.nlm.nih.gov/25362595/)

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

This treatment goes in the evening routine for safety and simplicity around sun exposure. A product of this type for sensitive skin needs calming plant extracts and gentle hydrators like centella asiatica and glycerin without potentially irritating citrus oils.

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

You can use this treatment with retinol by applying it after your cleanser and soothing toner, and before your moisturizer, but sensitive skin needs a product that pairs soothing plant extracts like Centella Asiatica with higher concentrations of calming ingredients to properly calm redness and irritation without the risk from citrus oils.

### How often should I use this serum?

You can use this treatment serum in the evening as part of your routine. Sensitive skin needs a product that pairs soothing ingredients like centella asiatica with gentle hydrators while completely avoiding potential irritants such as citrus oils.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/), [Indian Journal of Pharmaceutical Sciences, 2016](https://pubmed.ncbi.nlm.nih.gov/27168678/)

### Can it clog pores, cause breakouts or purging for sensitive skin?

This serum is unlikely to clog pores or cause breakouts, as reviewers report very low rates of breakouts. To feel truly calm and smooth, sensitive skin often needs higher amounts of proven soothing ingredients combined with zero irritating citrus oils.

### Is this serum fragrance-free and alcohol-free?

It has no drying alcohol and contains fragrance (citral and limonene).
