Which ingredient is primarily used to increase cell production and repair?

The ingredient that is primarily used to increase cell production and repair is retinoids. Retinoids, which include compounds like retinol and other derivatives of vitamin A, are well-established in skincare for their ability to promote cellular turnover. This means they stimulate the production of new skin cells and help in shedding old, damaged ones. This process leads to a smoother skin texture, fading of fine lines, and overall rejuvenation of the skin.

Retinoids work by increasing collagen production, which is crucial for skin repair and resilience. Their powerful effects on skin cell behavior make them a standard recommendation for addressing concerns like acne, pigmentation, and aging, reinforcing their role as key ingredients in skin health and maintenance.

While retinals and peptides also contribute to skin health, they do not primarily focus on increasing cell production to the same extent as retinoids. Retinals, which are a type of retinoid, have similar functions but are usually not as potent as retinoids themselves. Peptides play more of a role in signaling cellular processes and improving elasticity rather than directly increasing cell turnover. Acids, such as alpha and beta hydroxy acids, help exfoliate and remove dead skin cells but do not primarily focus on the repair and production of new
