The multifunctional serum can be used before makeup, alongside a moisturizer or sunscreen depending on your skin’s needs. You can apply it daily to maximize its effect for achieving a more even-textured, smoother, and brighter skin tone. It is also equally adept at keeping breakouts under control.

The details

An unscented serum for people with normal skin, it repairs damaged skin cells and helps manage hyperpigmentation associated with rosacea. It combines azelaic acid with the cooling properties of aloe to soothe and nourish the skin and give lasting results that will keep your skin pacified.


The serum feels light and soothing on the skin with no heavy feeling. Instead, it helps your skin feel silky and smooth after application and will dry quickly if you need to apply makeup right after it.

 It can be used along with a moisturizer by mixing it if the direct application does not get the expected results.

Ingredient quality

Using tried and tested skin-friendly ingredients, Cos De BAHA gives you flawless skin with a powerful combination of 10% azelaic acid, niacinamide, vitamin B, and hyaluronic acid.

Its oil-free and non-greasy construction doesn’t clog pores but does reduce the appearance of dark spots, scars, and blemishes.

Azelaic acid repairs damaged skin and minimizes hyperpigmentation. Niacinamide pitches in by shielding the skin from environmental stressors like pollution, sunlight, and toxins while hyaluronic acid keeps skin hydration intact.


With a combination of azelaic acid, niacinamide, and 50% organic aloe, not much can go wrong. Yet these gentle ingredients may not be gentle enough for more sensitive skins.

Azelaic acid helps treat skin conditions but can also cause the skin to burn on people with sensitive skin. It is recommended to use the serum on the chin before it is applied to the whole face to avoid any adverse reactions.

Value for money

This Korean formula does not break the bank when trying to achieve radiant results for your skin. Cos De BAHA contains 30ml of the serum with only 1 or 2 drops required for every application which makes it last a while.

Final verdict

Cos de BAHA gives you a serum that will rejuvenate dull and tired skin without irritating. It is also effective in minimizing imperfections like redness, inflammation, and discoloration.

However, manufacturers also advise that this serum is not suitable for sensitive skin types. Also, people trying azelaic acid for the first time should not start off with this product but look for something with a lower concentration.
