Every skincare routine has its secret weapon, and for red light therapy users, that weapon is the right serum. Applying a serum before your LED session prepares your skin, enhances penetration, and delivers essential nutrients. Serums containing ingredients like green tea extract, vitamin C, and peptides help calm inflammation and encourage collagen repair. Used consistently, this combination not only boosts your glow but also improves firmness and clarity, leaving your skin visibly rejuvenated and refreshed.
