Common Questions

Can I use this serum with other active ingredients like Retinol?

Yes, you can combine this serum with Retinol. Because the formula is low-irritation and fragrance-free, it works well alongside other actives, though it is best to introduce new products gradually to monitor your skin’s specific response.

How long does it take to see visible results?

Many users report noticeable texture improvement within one week of consistent application. For deeper, more stubborn pigmentation, continued use over four to eight weeks will provide the most significant visual reduction in dark spots.

Will this serum leave my skin feeling greasy or heavy?

Not at all. The serum is designed with a lightweight, fast-absorbing texture that penetrates deeply into the skin without leaving a sticky or heavy residue, making it ideal for layering under makeup.

Is this serum suitable for sensitive skin?

Yes. The formula avoids common irritants like fragrance and harsh alcohols, using Panthenol and Coral Moss to maintain a calm, hydrated barrier, making it safe for those with easily reactive skin.

Do I need to wear sunscreen while using this serum?

Yes, daily application of a broad-spectrum SPF is essential. While this serum treats existing pigmentation, consistent sun protection is the most effective way to prevent new dark spots from forming and to ensure the longevity of your results.

How does this serum help with acne scarring?

The 15% brightening trio (Tranexamic Acid, Niacinamide, and Arbutin) specifically targets the excess melanin left behind after a breakout. By fading these marks and supporting the skin’s natural renewal, it creates a more even, uniform complexion over time.
