What the product description says
“DESCRIPTION Cos De BAHA HB Hydroquinone Brightening Serum 30ml helps when treating different forms of hyperpigmentation. Improves the texture of your skin.”
Source: Lila Beauty

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

In addition, this product contains kojic acid, niacinamide, salicylic acid. This ingredient (ingredients) might help reduce hyperpigmentation, but the effect, if any, is likely to be small.

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: arbutin.

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.

The following ingredients - arbutin also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

Moisturizing
Not advertised by the brand · Niacinamide, Sodium hyaluronate + 2 more
Works well

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": sodium hyaluronate, aloe barbadensis leaf extract.

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

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.

At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles.

Anti-aging
Not advertised by the brand · Niacinamide, Lactic acid
Works well

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.

Exfoliation
Not advertised by the brand · Salicylic acid, Lactic acid
Works well

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: salicylic acid.

Product summary

"Cos De BAHA - Buy HB Hydroquinone Brightening Serum in Australia - K-Beauty Online Store" is effective for: Evens skin tone, Anti-blemish, Moisturizing, Anti-aging and Exfoliation

Ingredient callouts

  • A good concentration of Niacinamide (3.50% - 5.30%). 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.
  • Salicylic acid (0.55% - 1.30%). This is an oil-soluble exfoliating acid. Because of this property, it can work inside pores and help reduce the congestion. It has an anti-inflammatory effect and is used to treat acne. Because it is a quite strong exfoliator, be careful with using this product too often: it could result in over-exfoliation.
  • Humectants (sodium hyaluronate 1.00% - 1.50%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
