CUSKIN Dr. Solution Bifida Barrier Ampoule – a high-concentration Bifida Ferment Lysate ampoule for the skin barrier
CUSKIN Dr. Solution Bifida Barrier Ampoule is a mildly acidic, intensely hydrating facial ampoule designed for skin lacking comfort, moisture, and barrier support. Its concept is clear: the formula is built around no less than 76% Bifida Ferment Lysate, making it more than just a hydrating product with added fermented ingredients. It is an ampoule whose entire concept is based on combining fermented components with ingredients that help support skin comfort.
76% Bifida Ferment Lysate – the foundation of the formula, not just a highlight
What sets this ampoule apart is Bifida Ferment Lysate used as the base instead of a conventional water base. It is complemented by Lactobacillus and Lactococcus ferment lysates, as well as fermented soy, pomegranate, pear juice, and barley components. This composition is designed to support the skin barrier function and provide a longer-lasting feeling of hydrated, less dry skin. Alongside the fermented ingredients, the formula thoughtfully includes active ingredients that help support skin smoothness and the appearance of greater elasticity.
- Fermented ingredient complex: Bifida, Lactobacillus, and Lactococcus ferment lysates form the core concept of the ampoule – gentle daily support for the skin barrier.
- Moisture and lipid balance: Glycerin, diglycerin, squalane, sodium hyaluronate, Ceramide NP, and hydrogenated lecithin help reduce the feeling of dryness and leave the skin feeling soft.
- Additional smoothing focus: Niacinamide, adenosine, and peptides, including copper tripeptide-1, complement the formula with care focused on supporting a smoother, brighter, and firmer-looking complexion.
The ampoule has a lightweight, non-heavy texture that spreads easily and absorbs without noticeable stickiness, leaving the skin hydrated and softer to the touch. It fits naturally into a routine after toner and before moisturizer, especially when you want a consistent layer of comfort rather than aggressive active ingredients. It is the generous Bifida Ferment Lysate base that distinguishes this ampoule from many barrier-focused serums.
Usage
After cleansing your face and applying toner, apply a small amount of the product to the face and neck, then gently pat with your fingers until fully absorbed. Use morning and evening, and in the morning, follow with a moisturizer and sunscreen. Avoid contact with the eyes; if contact occurs, rinse immediately with water.
