Honest answers

Questions about this serum.

Can I use Peptide Serum with retinol or Vitamin C?+
Yes. Peptides play well with both. We recommend: Vitamin C in the morning, Peptide Serum either morning or evening, and our Retinol Alternative on alternating evenings if you want gentle renewal too.
How long until I see a difference?+
Most skin feels softer and calmer within the first week. Visible firmness and a smoother surface take 3-4 weeks of consistent, twice-daily use. Peptides build, they don't surprise.
Is it safe for sensitive skin?+
Yes. The formula is fragrance-free, allergen-label-free, and uses a single, well-tolerated peptide rather than a heavy actives cocktail. Patch-test inside the elbow for two evenings if your skin is reactive.
How long does one bottle last?+
With twice-daily use, one 30 ml bottle lasts roughly 8 weeks. Once-a-day use stretches it to about 12 weeks.
Why a glass bottle with airless pump?+
Peptides are sensitive to air and light. The airless pump and tinted glass keep the formula stable from the first day to the last drop.

Honest results
"After four weeks my skin holds itself differently. Less tight. More mine."

Time-released firmness, built into a daily ritual.

Peptides do not work like a glow trick — they work like sleep. You won't notice the single day. You will notice the third week.

Built for a long, gentle pattern: a thin, fast-absorbing essence with a stable peptide complex, a calming aloe base, and just enough hyaluronic acid to feel like a sip of water for tired skin.
