Product Summary
"SUNDAY RILEY - Saturn Sulfur + Niacinamide Spot Treatment" is effective for: Moisturizing, Anti-blemish, Evens skin tone and Anti-aging
Ingredient callouts
- A good concentration of Niacinamide (2.60% - 3.20%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
- Dipotassium Glycyrrhizate in this product (0.70% - 1.05%) can also further help improve the skin barrier. It might be able to calm down inflammation and reduce sensitivity. Dipotassium Glycyrrhizate is an active compound from the licorice root.
- In addition, this product contains Allantoin (0.90% - 1.10%). Allantoin is helpful in wound-healing and can help restore the skin barrier faster. It might also be able to improve scars, but the evidence is not very strong for this.
- Humectants (zinc pca 1.20% - 1.50%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production

Moisturizing
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": zinc pca, caprylyl glycol.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide

Exfoliation
What does the product description say?
High-strength sulfur helps to clear acne by drying up pore-clogging sebum while also removing dead skin cells.
Source: SpaceNK
This product does not contain effective exfoliating ingredients. It might be able to deliver physical exfoliation, that is scrub off some of the dead cells on the surface of the skin. We do not recommend physical exfoliation, because it is not uniform (some bits of skin can get exfoliated too much while others not at all). It can also traumatize the skin and aggrevate acne and other skin conditions.
