Peter Thomas Roth Collagen Skinjection Plumping & Firming Serum is a facial serum formulated with collagen peptides, exosomes, and skin barrier supporting ingredients. The product aims to help improve skin firmness and plumpness by delivering these components directly to the skin. Collagen peptides are included to support the skin’s natural collagen production, while exosomes are incorporated to assist in cellular communication and repair processes. The serum also contains ingredients that help strengthen the skin barrier, which can contribute to overall skin resilience and hydration.

This serum is designed for individuals looking to address signs of aging, such as loss of elasticity and fine lines. It is suitable for various skin types, including sensitive skin, due to its gentle formulation that avoids common irritants. The texture is lightweight and absorbs quickly, making it appropriate for use under moisturizer or makeup. It can be applied both morning and evening as part of a regular skincare routine.

The formula focuses on delivering targeted active ingredients without heavy oils or fragrances, which may appeal to those who prefer minimalist or science-backed skincare. The Collagen Skinjection serum is part of a broader product line that emphasizes skin rejuvenation through peptide technology and modern delivery systems. As with any skincare product, results may vary depending on individual skin condition and consistent use. The serum is packaged in a pump bottle for controlled dispensing and hygiene. This product does not claim to replace professional procedures but offers a topical approach to supporting skin structure and moisture retention.
