What the product description says
“Soothes irritation and exfoliates to reveal a radiant glow.”
Source: Lila Beauty

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: glycolic acid.

Glycolic acidKey activeEffect: HighAn alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid~3.3–5%
Moisturizing
Side benefit · Niacinamide, Ceramide np + 12 more
Works well

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, hydrolyzed 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: ceramide np.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide np, niacinamide

NiacinamideHeroEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. 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~4.4–6.5%
Ceramide npHero· EmollientEffect: HighA type of lipid similar to ceramides naturally present in skin. Helps to soften the upper layer of the skin and supports the skin barrier function to keep it hydrated. Can help to prevent inflammation in skin~0.1–0.4%

Anti-oxidation
Side benefit · Kojic acid, Adenosine
Works well

This product contains antioxidants (kojic acid) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

Anti-aging
Side benefit · Niacinamide, Glycolic acid + 2 more
Works well

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine, glycolic acid, 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.

NiacinamideKey activeEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture.

Works well

This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: glycolic acid

Evens skin tone
Side benefit · Niacinamide, Glycolic acid + 1 more

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: glycolic acid, kojic acid, niacinamide

Product summary

"Medicube - Buy Medicube Kojic Acid Turmeric Resurfacing Toner in Australia - Korean Skincare Online" is effective for: Moisturizing, Exfoliation, Anti-aging, Anti-blemish and Evens skin tone

Ingredient callouts

  • A good concentration of Niacinamide (4.40% - 6.50%). 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 acids (glycolic acid 3.30% - 5.00%). Their concentration is low, and they will not have a strong exfoliating effect. Instead, they work to support the skin natural acid mantle and to attract water (as humectants).
  • Ceramides (ceramide np 0.10% - 0.40%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.
  • Adenosine 0.10% - 0.35%. It is a chemical present inside our skin cells. A clinical trial confirmed that topical application of Adenosine in a low concentration can reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where our mimic is the most active, for example, in the corners of the eyes or on the forehead).
  • Humectants (glycerin 0.05% - 0.25%, sodium acetylated hyaluronate 0.05% - 0.25%, hydrolyzed hyaluronic acid 0.05% - 0.20% and sodium hyaluronate 0.05% - 0.30%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
