Product description
Key Benefits
- Brightens dull skin and enhances radiance.
- Helps improve the appearance of fine lines and wrinkles.
- Supports firmer, smoother-looking skin.
- Refines uneven texture and the appearance of pores.
- Reduces the appearance of dark spots and uneven skin tone.
holi (c) calcium & vitamin C is a dry powder treatment formulated with stable vitamin C and calcium to support a brighter, smoother and more youthful-looking complexion. Unlike traditional vitamin C serums, its water-free formula helps maintain ingredient stability until use, allowing the actives to remain effective throughout the life of the product.
The formula combines sodium ascorbyl phosphate, a gentle yet effective form of vitamin C, with calcium ketogluconate to brighten dull skin, improve the appearance of fine lines and support skin elasticity. Together, these ingredients help refine uneven texture, minimise the appearance of pores, reduce the look of pigmentation and post-blemish marks, and promote a firmer, more radiant complexion with continued use.
Why Agent Nateur is Healf
Their formulations are free from harmful synthetic fragrances, unnecessary fillers, and controversial ingredients. The brand prioritises ingredient transparency and uses naturally derived and responsibly sourced ingredients whenever possible, including organic and wild-crafted botanicals. Many of its products are considered safe for pregnant and breastfeeding women, though the brand always recommends consulting with a healthcare professional regarding individual needs.
Agent Nateur is committed to creating luxurious, high-performance beauty and wellness products that deliver exceptional results while maintaining the highest standards of safety, purity, and integrity.
Agent Nateur blossomed from founder Jena Covello’s heartfelt journey to heal from endometriosis and adenomyosis after enduring years of surgeries, pain, and conflicting medical advice. Discovering the power of natural ingredients, she created Agent Nateur, offering a beautifully curated range of luxurious, all-natural skincare and supplements that are safe, effective, and easy to incorporate into your daily rituals.
