What the product description says
“Infused with extracts derived from fruits, seeds and plants, this Micro-Peel Toner keeps skin refreshed and hydrated while removing stubborn residues and impurities.”
Source: Yesstyle

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~0.6–0.9%
UreaKey activeEffect: MediumNaturally present in skin (urea makes up about 7% of natural moisturizing factors in skin). Attracts water to the upper layer of the skin. Also has a positive effect on the skin barrier beyond the humectant action. Can enhance penetration of other ingredients. Is an exfoliating ingredient when used in high concentrations~0.25–0.45%
Tartaric acidKey activeEffect: MediumAn AHA (alpha-hydroxy acid). It oxidizes quickly which makes it less effective in skincare formulations. It can support skin's barrier and moisture levels~0.15–0.3%
Lactic acidUnder-dosedAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~0.45–0.65%

“Infused with extracts derived from fruits, seeds and plants, this Micro-Peel Toner keeps skin refreshed and hydrated while removing stubborn residues and impurities.”
Source: Yesstyle

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 collagen.

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: hydrolyzed collagen, persea gratissima fruit extract.

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

Evens skin tone

Works well

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

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

Anti-aging
Not advertised by the brand · Glycolic acid, Centella asiatica extract + 3 more
Works well

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: centella asiatica extract.

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.

Product summary

"Secret Key - Hyaluron Aqua Soft Toner" is effective for: Anti-inflammatory, Evens skin tone, Exfoliation and Anti-aging

This product could be helpful for: Moisturizing, but its actives are not the most effective or are not well-studied.

Ingredient callouts

  • This product contains acids (lactic acid 0.70% - 1.05% and glycolic acid 1.00% - 1.30%). 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). Lactic acid is particularly good in attracting water to the upper layer of the skin and improving the skin barrier.
  • Humectants (hydrolyzed hyaluronic acid 0.15% - 0.25%, trehalose 0.20% - 0.35%, sodium pca 0.20% - 0.40%, hydrolyzed collagen 0.35% - 0.65%, sodium hyaluronate 2.20% - 2.70% and glycerin 4.10% - 5.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Price

The product retails for 25.00A$ in Australia and for 20.25$ in the United States.
