[Product Review] Used for 2 Weeks, Refreshes Blemishes... Nature Republic ‘BT Fair C Blemish Serum’

20,000 Units Sold in 10 Days... Popular SNS Serum 'Jabti Sae Refresh'
Completed 9 Human Application Tests Including Pigmentation, Melanin, and Skin Texture

[Asia Economy Reporter Lee Seon-ae] Warm sunlight and colorful flowers signal the arrival of spring, but the accompanying UV rays and large temperature fluctuations easily dry out the skin, increasing concerns about blemishes and spots. Consumer interest in whitening products is rising for clear and bright skin like the radiant spring, and reflecting this demand, the beauty industry continues to release whitening and spot care products. Recently launched items stand out as multi-functional products that not only provide whitening but also care for moisture and skin tone. Among them, we personally tried Nature Republic’s ‘Vitafair C Spot Serum,’ which has become a hot topic on social networking services (SNS) after selling 20,000 units within 10 days of launch.

‘Vitafair C Spot Serum’ is a whitening functional spot care product containing 79.9% Jeju Green Lemon extract and Centella Asiatica (Cica) ingredients, which brighten dull skin, smooth it, and improve skin texture all at once. The key ingredient, Jeju Green Lemon, is known to have a higher vitamin C content than regular lemons, and it is certified pesticide-free with completed residual pesticide testing, ensuring safe use.

Nature Republic applied a cold brew method, soaking the green lemon at low temperature for 24 hours to slowly extract it, preserving the active ingredients intact. Adding Cica ingredients allows for spot care as well as firm skin texture in one step.

The first impression of the product is its fresh yellow vitamin-like formulation, which visually conveys a brightening effect for the skin. The light and refreshing texture spreads softly on the skin, absorbs quickly, and leaves a moist interior with a matte finish on the surface.

Generally, there is a perception that whitening products are drying, which caused some concern, but this product contains Jeju pesticide-free lemon extract instead of water and Cica ingredients, providing moisture and smoothing the skin texture. Also, for sensitive skin, vitamin C products can be burdensome, but the Cica ingredient offers a soothing effect, allowing safe use.

As the ‘Vitafair C Spot Serum’ one-month usage challenge continues on SNS, after using it consistently morning and evening for over two weeks, I felt my overall skin tone brighten and skin texture improve.

‘Vitafair C Spot Serum’ has completed nine human application tests including pigmentation, melanin, and skin texture at certified clinical institutions. The results showed that 95% of users experienced smoother skin texture immediately after one use, 100% had an even and brighter dull skin tone after one week, and 95.5% saw lightened spots, blemishes, and freckles after two weeks, verifying its efficacy.

For reference, whitening functional products are more effective when used together with sunscreen. Since mask-wearing has become routine, sunscreen use is often neglected, but unless the mask has a UV blocking filter, the skin is exposed to UV rays unprotected, which can cause spots and reduce the whitening product’s effectiveness. Also, functional essences containing high concentrations of AHA, BHA, or retinol can irritate the skin and should not be used together.
