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 brightening and antioxidant benefits for your normal skin, as multiple forms of vitamin C like 3-O-Ethyl Ascorbic Acid and Tetrahexyldecyl Ascorbate work to enhance radiance and protect against environmental stressors.
- Glycerin and caffeine provide general hydration and a revitalizing effect, supporting overall skin health without specifically targeting your redness and irritation.
- The product is safe for your normal skin with sensitivity, as it contains no harsh or prohibited ingredients that could cause irritation.

## How to apply

- Use your serum in the PM routine, starting 3 times a week before building up to daily use if your skin is happy.
- Apply the serum after cleansing and toning, but before putting on your moisturizer for the best results.
- 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 Youth to the People 15% Vitamin C + Clean Caffeine Energy Serum work for sensitive skin?

This serum works moderately well for sensitive skin, offering brightening and antioxidant benefits, but it does not specifically target redness and irritation. A product of this type needs soothing and calming ingredients like niacinamide and snail secretion filtrate to properly care for sensitive skin.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/)

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

This serum works for sensitive skin because it contains glycerin for hydration and squalane to support overall skin health. However, a product for this skin needs calming ingredients that specifically target redness and irritation.

### What does Vitamin C do for sensitive skin?

Vitamin C helps brighten skin, smooth out fine lines, and fade dark spots. Clinical studies show it is generally safe and well-tolerated when improving overall skin quality.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/)

### What does Caffeine do for sensitive skin?

Caffeine is unlikely to irritate sensitive skin, as it has a very safe profile and low risk of causing trouble when applied topically. It helps calm the skin and protect it against everyday stressors while keeping your skin barrier comfortable and smooth.

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

This treatment goes in the evening routine after your toner and before your moisturizer. Putting it in the evening keeps things simple and provides extra safety around sun exposure.

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

You can use this serum alongside retinol by applying the vitamin C in the morning and saving your retinol for your evening routine. This spacing helps prevent overwhelming your skin with too many strong active ingredients at once.

### How often should I use this serum?

This treatment may be used in the evening once a week for sensitive skin, and can be used more often if your skin tolerates it well without redness or irritation. A product for this skin needs soothing ingredients like centella asiatica, allantoin, or ceramides to calm irritation while providing hydration.
Sources: [Facial Plastic Surgery, 2014](https://pubmed.ncbi.nlm.nih.gov/24488631/)

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

This serum is unlikely to clog pores or cause breakouts for sensitive skin because it contains no heavy or pore-blocking ingredients. It is safe for your skin type, though products with extra calming ingredients to soothe redness and irritation fit sensitive skin even better.

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

Yes, it has no fragrance and no drying alcohol.
