Product Summary
"TIRTIR - Niacinamide 20% Serum" is effective for: Moisturizing, Anti-aging, Evens skin tone, Anti-blemish and Exfoliation
Ingredient callouts
- A good concentration of Niacinamide (5.60% - 6.90%). 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.
- This product contains an effective form of Retinoids (vitamin A): retinol 0.35% - 0.65%. Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores. The downside of Retinoids is that they can be irritating. If you are not already using a Retinoid in your routine, it is best to start slowly and apply the Retinoid product only a few times per week. If your skin tolerates it well, you can gradually increase the frequency to daily.
- Humectants (zinc pca 0.05% - 0.10%, sodium hyaluronate 0.30% - 0.55%, hydrolyzed hyaluronic acid 0.30% - 0.55%, hyaluronic acid 0.35% - 0.60% and glycerin 4.00% - 4.90%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
Anti-aging
What does the product description say?
Niacinamde 20%, Alpha Arbutin 2%, and Glutathione offer transparent and sparkling skin, while Retinol 500IU and Zinc PCA create younger-looking skin with effective anti-aging care and calm-only irritation on skin with intense soothing care.

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains retinol, 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.
Two steps removed from the active form of vitamin A - retinoic acid. Once converted to the retinoic acid in the skin, retinol is proven to be effective against all signs of aging.

This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
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. The following ingredients in this product do the job:
glycerin, hyaluronic acid.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: cholesterol, brassica campestris sterols.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin. A version of it is naturally present in skin
