FAQ Hydra Calculus - PFAS tested Sublime Hydration

Q: What makes Hydra Calculus different from other hydrating serums?
A: Hydra Calculus is a true multi-tasker. While most serums focus only on surface hydration, ours is scientifically formulated to perform three critical functions: 1) Deeply hydrate with a blend of Hyaluronic Acid and humectants, 2) Repair the skin barrier with Ceramide NP and Niacinamide, and 3) Combat signs of aging with a powerful peptide complex. Plus, it delivers all this with a completely weightless, non-greasy feel and the proven purity of Fluorocert certification.

Q: Is this serum suitable for my skin type?
A: Yes, absolutely. Its intelligent formulation makes it ideal for:

  • Oily & Combination Skin: The lightweight, non-comedogenic (won't clog pores) formula provides essential hydration without heaviness.

  • Dry & Dehydrated Skin: It delivers intense, multi-level moisture and reinforces the barrier to prevent future water loss.

  • Sensitive Skin: Soothing ingredients like Bisabolol and protective Ectoin help to calm and strengthen vulnerable skin.

  • Mature Skin: The peptide complex and barrier-supporting ingredients target fine lines and loss of resilience.

Q: How and when should I use it in my routine?
A:

  • When: Use it both morning and night for best results.

  • Order: Apply after cleansing and toning, but before heavier creams or oils. If using our Vitamin C+ Serum, apply Vitamin C first in the AM, followed by Hydra Calculus.

  • How: Dispense 2-3 drops into your palms and gently press it into your face and neck. There's no need to rub aggressively.

Q: Can I use this with other active ingredients like Retinol or Vitamin C?
A: Yes, Hydra Calculus is an excellent partner for actives. It acts as a soothing and hydrating base that can help mitigate potential irritation from powerful ingredients like Retinol. When using with Vitamin C (like our own Vitamin C+ Serum), apply Vitamin C first on clean, dry skin, wait a minute for absorption, then follow with Hydra Calculus to hydrate and lock in the benefits.

Q: How long until I see results?
A:

  • Immediately: Your skin will feel softer, smoother, and more supple after the first use.

  • 1-2 Weeks: With consistent use, you should notice improved hydration, a more dewy complexion, and a calmer feel.

  • 4-8 Weeks: The long-term benefits like strengthened barrier function, visibly plumper skin, and diminished fine lines become more apparent as peptides and ceramides work to rebuild your skin's infrastructure.

Q: What does "Fluorocert Certified" mean for this product?
A: This is our promise of verified purity. It means that every batch of Hydra Calculus Serum has been independently tested by our parent company, Fluorocert, and certified to contain low or non-detectable levels of PFAS (forever chemicals) and organic fluorine. We go beyond marketing claims to provide you with transparent, scientific proof that your skincare is clean and safe.

Q: Is this product cruelty-free and vegan?
A: Yes! We are proud to be 100% cruelty-free. We never test on animals. Please check the full ingredient list to confirm it meets your vegan standards, as formulations can occasionally change.

Q: Why is the texture so lightweight? Does it still work for very dry skin?
A: The lightweight texture is a result of advanced formulation science, not a lack of potency. We've used innovative ingredients like C 15-19 Alkanes and a carefully balanced emulsion system to create a serum that penetrates instantly without a heavy film. This makes it exceptionally effective for dry skin, as it delivers nourishing oils and humectants deeply into the skin where they're needed, rather than just sitting on the surface.
