Estee Lauder, L'Oreal, and ELF Beauty are ramping up in India as growth slows in developed markets, Reuters reported. India's luxury beauty market is set to jump 5-fold to $4 billion by 2035, driven by young, affluent, social-media savvy consumers. Estee Lauder has invested in forest essentials and is tailoring local launches, while ELF and others expand via multi-brand stores.
