- RayGel reduced skin reaction severity with a lower average score of 93.7 compared to 123.3 for the placebo group in patients undergoing whole breast external-beam irradiation. ([American Journal of Surgery, 2005](https://pubmed.ncbi.nlm.nih.gov/15862509/))

- 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 Paula's Choice 25% Vitamin C + Glutathione Clinical Serum work for dry sensitive skin?

This serum works moderately well for dry sensitive skin by brightening your tone and providing essential hydration, though other products fit it better. To achieve a top-tier fit for this skin type, a treatment needs maximum hydrating and nourishing ingredients, an optimal texture and pH, and a gentle formula that protects the skin barrier without causing irritation.

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

This serum works for your skin because glycerin and sodium hyaluronate help attract and retain moisture, while tetrahexyldecyl ascorbate and glutathione provide antioxidant support and improve radiance. To fit dry sensitive skin just as well as top-rated treatments, a product like this also needs soothing and barrier-supporting ingredients that deliver deep hydration without any risk of irritation.

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

Vitamin C helps brighten and smooth dry sensitive skin while reducing wrinkles and improving elasticity. It is generally well tolerated and unlikely to cause irritation when properly formulated, leaving the skin looking more radiant.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/), [Antioxidants, 2024](https://pubmed.ncbi.nlm.nih.gov/38397772/)

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

Glutathione helps improve moisture content and smoothness while reducing oxidative stress, making it a helpful option for dry sensitive skin. This ingredient may enhance hydration and elasticity while maintaining a gentle profile. To properly care for dry sensitive skin, a product of this type needs soothing and hydrating ingredients that support the skin barrier.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2014](https://pubmed.ncbi.nlm.nih.gov/25378941/), [Journal of the European Academy of Dermatology and Venereology, 2024](https://pubmed.ncbi.nlm.nih.gov/38189670/)

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

This treatment goes in the evening routine after your toner and before your moisturizer. Dry and sensitive skin of this type needs a gentle, fragrance-free formula rich in soothing hydrators like glycerin and hyaluronic acid to lock in moisture without causing irritation.

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

You can use this serum with retinol, but apply retinol at night and this vitamin C treatment in the morning to help prevent irritation on dry and sensitive skin. To truly thrive, dry and sensitive skin needs products of this type that also deliver rich, soothing hydrators and gentle barrier-supporting ingredients.

### How often should I use this serum?

Apply this treatment in the evening as part of your routine to keep things simple and safe around sun exposure. Dry and sensitive skin of this type needs products packed with calming ingredients and deep moisture like glycerin and sodium hyaluronate.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2014](https://pubmed.ncbi.nlm.nih.gov/25378941/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

This serum is unlikely to clog pores or cause breakouts for your dry and sensitive skin, as reviewers rarely report these issues. To work best for this skin type, a product of this type needs soothing components and hydrating ingredients like glycerin and sodium hyaluronate.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Yes, it has no fragrance and no drying alcohol. Cetyl alcohol is a fatty alcohol, which soften the skin.
