  • Description
  • The serum contains 2% Hydroquinone, a potent skin-lightening agent known to reduce the appearance of hyperpigmentation, dark spots, age spots, and other forms of discoloration. It works by decreasing the number of melanocytes, which are cells responsible for pigment production, leading to a more evenly toned skin​.

    Besides Hydroquinone, the serum is enhanced with 4% Arbutin and 4% Niacinamide. Arbutin helps to further inhibit melanin production, while Niacinamide, also known as Vitamin B3, is recognized for its ability to improve skin texture, diminish dullness, and strengthen the skin's barrier function. Together, these ingredients contribute to a significant improvement in hyperpigmentation, melasma treatment, and overall skin brightening​​​.

    Consistent use of this serum is key to achieving visible results. It may take around four weeks to start noticing effects and several months for the full benefits to be realized. Regular application as part of a comprehensive skincare routine will yield the best outcomes in terms of fading dark spots, freckles, hyperpigmentation, and melasma while also refining and hydrating the skin's surface​​​.

    The COS DE BAHA (HB) 2% Hydroquinone Brightening Serum is, therefore, a targeted solution for those looking to correct hyperpigmentation and achieve a brighter, more even skin tone.

  • How to Apply
  • Spot test first. Use it at night. Apply serum to clean skin every other day and work your way up to daily use. You'll begin to see results within 4 weeks. Be sure to wear sunscreen during the day in areas where you've used this serum.

    After using this product continuously for 60 days you'll need to give your skin a break and stop using the serum for 30 days. During the 30-day break, we recommend using Cos De BAHA Vitamin C Serum + AHA/BHA Toner to maintain your new glow. You can repeat this cycle to keep your skin looking bright and youthful.

    Good for lightening dark spots. Use a small amount and will need to use it over time to see results.

    Work but not as a miracle

    I have been using it for 2 weeks now and it does work in lightening the dark spots. I think consistent application will bring great results. To be used only on the spots as it dries out skin i noticed.
