Appearance plays an essential role in many people’s lives, so individuals are willing to go the extra mile to maintain healthy, radiant skin. However, due to busy schedules and daily routines, many—especially women—often don’t have time to care for their skin, particularly their face.

One of the effects is skin barrier dysfunction, which can be caused by many factors besides stress. Other contributing factors include UV radiation and lifestyle habits. These can affect a person's skin condition, leading to dull skin. As a result, many women focus on addressing this skin concern.

This has led to a growing trend in skincare treatments to combat dull skin. According to Custom Market Insight, the global dull skin treatment market was valued at USD 6.3 billion in 2024 and is projected to reach USD 13.6 billion by 2033. Popular treatments include the use of exfoliants, antioxidants, moisturizers, and sunscreen.

BeautyData also reports that consumers' most sought-after product benefits are those that target dull skin. According to BeautyData, brightening products ranked 9th in total sales, reaching over 35.44 million from April 2024 to March 2025. This indicates that consumers also have a strong interest in brightening products.

These key benefits are also found in SpecPlex® Gloss, a formulation made from a blend of six water-soluble ingredients including Lactobionic Acid, Mandelic Acid, Tranexamic Acid, Carnosine, Nonapeptide-1, Niacinamide. SpecPlex® Gloss helps smooth the skin by removing dead skin cells and reducing melanin production.

In addition, SpecPlex® Gloss contains ingredients that strengthen the extracellular matrix (ECM) by promoting the production of collagen and glycosaminoglycans (GAGs). This helps the skin become firmer and more radiant, effectively combating dullness. The six active ingredients in SpecPlex® Gloss work together to achieve multi-level, multi-target, multi-channel results—promoting even skin tone, reducing dullness, minimizing wrinkles, and deeply moisturizing the skin from the inside out.

SpecPlex® Gloss was tested for its brightening effects in a study involving 37 women aged 25 to 55. The product was applied twice daily—after cleansing the face in the morning and evening—for 28 days. The dosage used during the experiment was 5%.

By day 28, results showed that skin tone appeared more radiant, melanin function became more optimal in protecting against UV rays, and overall skin brightness improved.

According to the result of cell tyrosinase activity test and cell dopa staining experiment, SpecPlex® Gloss can inhibit tyrosinase activity in melanocytes. The inhibition rate is 58,5% at 0,1% and IC50 is 633μg/mL（≈0.0633%).

In addition, it also has a significant inhibitory effect on the production of melanin in B16F10 melanocytes. The inhibitory effect on the production of melanin in B16F10 melanocytes, the inhibitory rate reached 41,4% when the concentration was 0,4%. The inhibition is concentration dependent.

This image also shows that the darker and larger brown areas indicate higher tyrosinase activity within the cells.

SpecPlex® Gloss has been proven to brighten the skin, helping to boost your confidence. If you're developing a skincare product focused on skin brightening, you can incorporate SpecPlex® Gloss and collaborate with SML.
