Acetyl Tetrapeptide-2
Acetyl Tetrapeptide-2 is a lab-crafted peptide used in anti-ageing skincare to help improve skin firmness and resilience. Often found in serums, creams and eye treatments, it is popular with those looking for a more lifted, youthful appearance without irritation.
How it works in skincare
In cosmetics and skincare Acetyl Tetrapeptide-2 works by mimicking certain natural signalling molecules in the skin that support the production of key structural components such as collagen, elastin and glycosaminoglycans. By helping to reinforce the dermal-epidermal junction and improve skin density it delivers a firmer, more toned feel and a visibly lifted appearance, making it a favourite ingredient in targeted facial and neck products.
