A water-free oil serum that cares for dryness, firmness and dullness together

BioSatin Serum from CHRISTINA, the Israeli dermatologist-developed skincare brand. By using no water at all and blending active ingredients into an oil base, this serum addresses dehydration beneath the surface and age-related signs — loss of firmness, dullness, fine lines. Vitamins, retinol, squalane and grape seed oil help skin hold moisture from within, balancing the barrier while building glow, bounce and smoothness.
Add it as one extra step to your morning and evening routine — ideal for dry seasons and for anyone concerned about firmness and glow.

What to expect

• Locks in moisture: formulated on an oil base without water, it helps prevent moisture evaporating from the stratum corneum and reduces that dry feeling from within.
  
  
• More firmness and bounce: retinol derivatives, squalane and grape seed oil support collagen production and skin elasticity.
  
  
• Refined texture and a smooth surface: works towards skin that feels plump and smooth to the touch.
  
  
• Less dullness and unevenness: a vitamin C derivative helps curb melanin production for a brighter-looking complexion.
  
  
• Care for signs of ageing (fine lines, sagging): antioxidants (ubiquinone / coenzyme Q10) and retinol-family ingredients work on the signs that appear with age.
  
  
• Better makeup application and finish: a veil-like oil layer brings moisture and glow to skin before makeup, improving how base makeup sits.

Quality you can trust

• Water-free formulation: no water at all, with active ingredients at high concentration. Improves how efficiently they are delivered and how stable they remain.
  
  
• Botanical oils: squalane, grape seed oil and calendula flower oil, chosen for how readily they sink in and how well they hydrate.
  
  
• Antioxidant and conditioning ingredients: ubiquinone (Q10), beta-carotene, a vitamin C derivative and retinol — a composition focused on age care.
  
  
• A trusted brand through official channels: an Israeli brand, distributed in Japan through official retailers as genuine product. Note that the brand also issues warnings about counterfeits and imitations.
  
  
• For morning and evening: usable both morning and night, designed to fit into a busy routine.

Who it’s for

• Those who feel dryness, a lack of moisture, or dehydration beneath the surface in their morning and evening routine

• Those concerned about fine lines, loss of firmness, dullness or uneven tone that have come with age

• Those curious about oil serums but worried about greasiness or clogged pores (the quality oils used sink in readily)

• Those who want to take the finish of their makeup up a level, adding glow and smoothness

• Those who choose a serum on brand trust and ingredient composition
