## Questions and answers

### What makes Polyphenol Dark Spot Diminisher a great fit for dry skin?

This treatment is a great fit because it brightens uneven skin tone with niacinamide and diglucosyl gallic acid while grape seed oil and shea butter deeply soften dry areas. Glycerin and other fruit extracts also help boost moisture and support your skin barrier without causing irritation.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [International Journal of Cosmetic Science, 2022](https://pubmed.ncbi.nlm.nih.gov/35211990/)

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

This cream is a great fit for dry skin because Vitis Vinifera Seed Oil and shea butter soften rough spots while niacinamide and diglucosyl gallic acid brighten your tone. Glycerin and Terminalia Ferdinandiana Fruit Extract also boost hydration and support your skin barrier, helping to keep flaky skin smooth and calm.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [International Journal of Cosmetic Science, 2022](https://pubmed.ncbi.nlm.nih.gov/35211990/)

### What does Niacinamide do for dry skin?

Niacinamide helps dry skin by strengthening the skin barrier, increasing hydration, and reducing water loss. It supports ceramide production and helps keep the surface smooth and calm. This ingredient tends to be very well tolerated and is unlikely to irritate dry skin.
Sources: [Journal of Cosmetic Dermatology, 2004](https://pubmed.ncbi.nlm.nih.gov/17147561/), [Journal of Cosmetic Dermatology, 2026](https://pubmed.ncbi.nlm.nih.gov/42108609/)

### What does Diglucosyl Gallic Acid do for dry skin?

Diglucosyl gallic acid helps brighten skin tone and reduce dark spots caused by the sun while providing antioxidant benefits. Because it is mainly used for brightening and uneven tone, dry skin also needs hydrating ingredients like hyaluronic acid or ceramides to stay soft and smooth.
Sources: [International Journal of Cosmetic Science, 2022](https://pubmed.ncbi.nlm.nih.gov/35211990/)

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

This treatment goes in the evening routine after cleansing and before moisturizing. Putting treatments in the evening provides simplicity and extra safety around sun exposure.

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

You can use this cream with retinol by applying your retinol first, waiting for it to absorb, and then following with this treatment in your evening routine. This helps brighten dark spots while keeping dry skin soft, though using two active products at once may occasionally lead to mild irritation.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [International Journal of Cosmetic Science, 2022](https://pubmed.ncbi.nlm.nih.gov/35211990/)

### How often should I use this cream?

Use this treatment in your evening routine. It fits dry skin well, helping to brighten dark spots while providing deep hydration and softening dry patches.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [International Journal of Cosmetic Science, 2022](https://pubmed.ncbi.nlm.nih.gov/35211990/)

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

This cream is unlikely to clog pores or cause breakouts for your dry skin because it contains no harsh ingredients and features nourishing oils that help keep skin smooth and comfortable. It also does not contain active ingredients that typically trigger skin purging.

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

It has no drying alcohol and contains fragrance (parfum).
