Alastin is a professional skincare brand known for TriHex Technology, a peptide and botanical blend that supports the skin's own renewal of collagen and elastin. The range runs across serums, moisturizers, mineral sunscreens, an eye and a neck treatment, and body care. Most people arrive for the Regenerating Skin Nectar or the Restorative Skin Complex, then build the rest of the routine around it. It's a corrective, results-led line for firmness and aging skin.
