Ampoule and cream CuSkin care for the skin barrier

This CUSKIN Dr. Solution Bifida Barrier set pairs a concentrated ampoule with a rich cream, both built around fermented bifida lysate to support a comfortable, hydrated skin barrier. It's a fragrance-free, dye-free routine made with sensitive and easily reactive skin in mind, and it works for all skin types.

What's in the set?

A two-step duo: the Bifida Barrier Ampoule for targeted hydration and a smoother-looking complexion, followed by the Bifida Barrier Cream to seal in moisture and soften the skin's feel.

Bifida Barrier Ampoule

A high-concentration serum with 76% bifidobacterial lysate and peptides. It has a gently acidic formula at pH 6.4, so it stays in tune with skin's natural balance. The texture is dense but spreads and absorbs easily, without leaving a sticky film.

Key ingredients:

• 76% Bifidobacterial Lysate — delivers intensive moisture and helps even the look of skin tone.
• Copper Tripeptide-1 — a peptide that supports a firmer, smoother appearance and the look of skin elasticity.
• Adenosine — helps skin look firm and smooth.
• Niacinamide (Vitamin B3) — brightens the look of the complexion and helps minimise the appearance of pores.
• Nasturtium Extract — an antioxidant ingredient that helps comfort the look of the skin.
• Ceramides — help reinforce the moisture barrier and keep skin feeling supple and hydrated.

Bifida Barrier Cream

A nourishing cream with bifidobacteria for sensitive skin. It moisturises intensively, softens and smooths, and helps support the protective barrier so skin feels comfortable and looks healthier.

Key ingredients:

• Bifida Ferment Lysate (65%) — supports the barrier and helps skin feel nourished, leaving it looking smooth and supple.
• Niacinamide — helps reduce the look of uneven tone, tightens the appearance of pores, soothes and brightens.
• Macadamia Oil & Shea Oil (Butter) — soften and nourish, helping limit moisture loss and protect against everyday environmental stress.
• Copper Tripeptide-1 — supports a firmer, healthier-looking skin surface.
• Acetyl Hexapeptide-8 — a peptide that helps smooth the look of skin.
• Amino Acids — help keep skin feeling supple and conditioned.
• Ceramides NP — reinforce the protective layer and help limit moisture evaporation for lasting comfort.
• Adenosine — helps improve the look of skin elasticity and smoothness.
• Nasturtium Extract — an antioxidant ingredient that helps comfort and condition the look of skin.

Who is it for?

Anyone wanting a barrier-focused routine, particularly those with sensitive or easily reactive skin. Both products are fragrance-free and free from artificial colourants. Suitable for men and women, and for all skin types.

How do you use it?

After cleansing and toning, apply a few drops of the Bifida Barrier Ampoule and pat gently until absorbed. Follow with the Bifida Barrier Cream to lock in hydration. Use morning and evening as the last steps of your skincare routine.
