Cos de Baha VA Vitamin C 15 Ascorbic Acid Serum

What it is

Cos De BAHA VA Serum is a 30ml treatment serum with 15% L-ascorbic acid (vitamin C). The current formula also includes arbutin, panthenol and sodium hyaluronate.

Why choose it

• Focused vitamin C step: consider it when supporting a brighter, more even-looking complexion is your main treatment goal.
• High-strength active: 15% L-ascorbic acid can be more demanding on tolerance than a basic hydrating serum.
• Do not stack for speed: if you are new to strong actives, avoid introducing several acids, exfoliants or other potentially irritating treatments at the same time.

Consider another option if

Your skin is currently stinging, peeling or otherwise irritated, or if you want a gentler beginner treatment rather than a concentrated L-ascorbic acid serum.

How to use

Cos De BAHA advises patch testing first and starting with a small amount. Apply after cleansing and before moisturiser. In the morning, finish with sunscreen.

Simpli Start-Safe: introduce it gradually and judge tolerance before increasing use. Stop if persistent irritation develops.
