MEDITHERAPY Retinal Skin Booster Serum is a facial serum formulated with retinaldehyde and niacinamide, designed to address signs of aging such as fine lines and loss of firmness. Retinaldehyde, a retinoid derivative, is included for its role in supporting skin renewal and evening texture, while niacinamide contributes to a more radiant complexion and helps strengthen the skin barrier. This serum also contains hydrating ingredients to provide moisture without heavy residue, making it suitable for all skin types, including those with sensitive or dry tendencies.

As a K-beauty product, this serum emphasizes a gentle yet effective approach, with a lightweight, water-like consistency that absorbs quickly. The 5.07 fl oz (150 ml) bottle offers a generous volume at an accessible price point, allowing for regular use as part of a daily skincare routine. The formula is free from aggressive irritants when properly introduced, though users new to retinoids may wish to start with gradual application. Regular use can help improve overall skin texture and radiance, while the inclusion of niacinamide assists in soothing and brightening.

This serum is suitable for individuals looking for an anti-aging boost that combines retinoid efficacy with moisturizing and barrier-supporting benefits. It can be applied after cleansing and before moisturizer, both morning and evening, with proper sun protection during the day. The product does not contain artificial fragrances or essential oils that commonly cause irritation, focusing instead on a simple, functional ingredient list. MEDITHERAPY Retinal Skin Booster Serum is a straightforward option for those seeking consistent, no-fuss skincare that prioritizes balanced formulation over exaggerated claims.
