Individuals are increasingly influenced by societal expectations and the behaviors of their social circles, prompting greater alignment with environmentally responsible choices. In addition to social factors, green purchase intention is often shaped by subjective norms, health consciousness, and environmental awareness, which together form the basis of consumers' motivations to engage in sustainable (Lavuri.

Katadata Insight Center (KCI) conducted a survey with many consumers in Indonesia who reported purchasing eco-friendly products. Based on the chart above, the most dominant reason driving consumers to buy eco-friendly products is the desire to preserve the Earth, accounting for 60. This indicates that environmental awareness has rapidly increased in Indonesian society, with consumers becoming more concerned about the impact of the products they use. In addition to environmental awareness, consumers also choose ecofriendly products because they are satisfied with the quality of the product. This suggests that eco-friendly products are evaluated not only on their environmental aspects but also on quality and consumer satisfaction (Srivastava et al. , 2. Another factor is the positive image and brand preference, which shows that brand factors and brand image still play a crucial role in the purchase decision of eco-friendly products (Yang et al. , 2. Research shows that total sales in the marketplace from April to June 2022 amounted to IDR 292. 4 billion with a total of 3. 8 million transactions.

AvoskinAos sales still lag far behind its competitors, such as Somethinc. Scarlett, and MS Glow. Somethinc recorded sales of IDR 53. billion, followed by Scarlett at IDR 40. 9 billion, and MS Glow at IDR 29. 4 billion. AvoskinAos sales are still significantly behind its competitors, indicating that Avoskin has room for improvement in areas such as purchase decision processes, online consumer reviews, brand image, and brand knowledge (AvoskinBeauty, 2.

In the context of beauty products, packaging often contributes to waste, and the production process uses resources that require significant energy or cause environmental damage (Hadi & Keni, 2. demonstrated by Somethinc and Avoskin, skincare companies are starting to shift toward a green marketing concept to reduce their negative impact on the environment (Seelig et al. One important aspect in understanding consumer behavior toward eco-friendly skincare products is subjective norms, which refer to an individual's belief in complying with the guidance or recommendations from those around them. The trend of eco-friendly products is becoming increasingly popular, especially among Generation Z, who are highly concerned about environmental issues. Research conducted in Batam and Jakarta shows that consumers with high environmental awareness, supported by positive subjective norms, are more likely to be interested in purchasing eco-friendly skincare products (Diarti & Hesniati, 2.

Similarly, social media marketing emerges as a highly effective tool for expanding brand reach, fostering customer interaction, and boosting consumer involvement in green initiatives. Additionally, subjective norms, encompassing social pressures from family, peers, and broader societal expectations, encourage individuals to choose sustainable products. Environmental awareness is identified as the primary motivator for purchasing eco-friendly items, followed by product quality, customer satisfaction, and brand preference.

Scarlett, and MS Glow, indicating opportunities to refine marketing strategies and improve brand perception.

However, while Avoskin has established itself as a leading eco-friendly brand, its sales performance indicates room for improvement compared to its main competitors.

Social media marketing strategies significantly enhance brand awareness and customer engagement, while subjective normsAisuch as the influence of family, peers, and societal expectationsAiplay a substantial role in shaping individual purchasing decisions for eco-friendly products. Based on these findings, businesses are encouraged to strengthen interactive social media campaigns, promote user-generated content, and support community-driven initiatives to ensure long-term consumer engagement with sustainable products. Future research should investigate how demographic variables, including age and educational background, moderate the effects of E-WOM and social norms on consumer behavior. REFERENCES
