The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Germany.

Brand: [IT Cosmetics](https://lovi.care/skincare/de/brands/it-cosmetics)
Category: [Serums and treatments](https://lovi.care/skincare/de/best/serums)

This fit is calculated for the concerns frequently associated with dry sensitive skin: flakiness, tightness, redness, fine lines, and wrinkles. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for dry sensitive skin; other serums fit it better.

## Why this fit

- Offers excellent brightening and evening of skin tone due to the presence of 3-O-Ethyl Ascorbic Acid and Niacinamide, but is moderately unsuitable for your dry skin as salicylic acid can be drying and lacks deeply hydrating ingredients.
- While it provides general skincare benefits like hydration from Glycerin, these are mostly supportive and do not address your dry or flaky skin concerns.
- The formula is safe for your dry and sensitive skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

## How to apply

- Use this PM routine for your evening skincare. Start using the serum 3 times a week and increase to daily use if your skin feels comfortable.
- Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
- Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
- Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.

## Questions and answers

### How well does IT Cosmetics Bye Bye Dark Spots work for dry sensitive skin?

This serum works for your skin, though other products fit it better because salicylic acid can be drying. While it is safe and provides general hydration and brightening, dry skin needs products with effective hydrating and nourishing ingredients, ceramides, and optimal moisture retention to support the skin barrier.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/)

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

Niacinamide and 3-O-Ethyl Ascorbic Acid help brighten and even out skin tone, while glycerin provides basic hydration. However, because your skin is dry, this treatment needs extra nourishing and moisturizing ingredients, ceramides, and deeply hydrating components to properly lock in moisture and support your skin barrier.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/)

### What does Niacinamide do for dry sensitive skin?

Niacinamide helps dry sensitive skin by calming irritation and keeping moisture locked in so your face feels soft and smooth. It works to build up your skin barrier and calm redness while being very gentle and unlikely to cause irritation.
Sources: [Journal of Cosmetic Dermatology, 2004](https://pubmed.ncbi.nlm.nih.gov/17147561/), [International Journal of Pharmaceutics, 2013](https://pubmed.ncbi.nlm.nih.gov/23220080/)

### What does 3-O-Ethyl Ascorbic Acid do for dry sensitive skin?

3-O-Ethyl Ascorbic Acid helps protect dry and sensitive skin from environmental damage, calms irritation, and keeps the skin smooth and bright. It is unlikely to cause trouble and may help reduce redness while supporting overall skin health.
Sources: [Free Radical Biology & Medicine, 2025](https://pubmed.ncbi.nlm.nih.gov/39778604/), [Journal of Cosmetic Dermatology, 2012](https://pubmed.ncbi.nlm.nih.gov/23174055/)

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

Apply this treatment serum in the evening after your soothing toner and before your moisturizer. Treatments are used at night for simplicity and extra safety around sun exposure, though this formula needs extra rich hydrators to keep dry skin soft.

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

You can use this serum with retinol by applying your retinol first in your evening routine, but this product may be drying for your skin since it lacks deeply hydrating ingredients. A treatment for dry and sensitive skin needs deeply nourishing ingredients and gentle hydrators to keep skin soft and smooth.

### How often should I use this serum?

You can use this serum in the evening once a week to start, as it contains an exfoliating acid that can be drying. If your skin feels comfortable and stays smooth, you may carefully use it more often. This product type needs rich hydrators like ceramides or hyaluronic acid to keep dry skin soft and comfortable.

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

This serum is unlikely to cause breakouts or clog pores on dry sensitive skin, as its formula is generally safe and free of harsh irritants. However, because it contains salicylic acid, it needs extra soothing and deeply hydrating ingredients to properly care for dry skin.

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

It has no drying alcohol and contains fragrance (limonene, geraniol, and citronellol).
