THE RITUAL THREE MINUTES
Morning and night.
1
Cleanse
Begin with clean, slightly damp skin—it helps the serum glide and absorb beautifully.
2
Apply the Serum
Press two to three drops into the skin, working outward from the centre of the face. Press gently rather than rubbing.
3
Seal
Follow with your moisturiser to seal in hydration and complete the ritual.
What Happens After You Order
A quiet, considered process — from checkout to your first application.

So far I’m really enjoying it. My skin feels much more moisturized. The reason I give a 4 instead of 5 is because my package arrived a bit damaged but serum was fine

Packaging was simple and arrived intact. I’ve only been using it for about a week so I can’t speak on long-term results yet, but my skin feels really quite soft after applying.

Good Questions
Straight answers about the formula, the routine, and what to expect.
A 30ml facial serum built around NAD+ and collagen extract, formulated to support skin firmness and hydration. It layers into your existing routine — no separate ritual required.
Our NAD+ Firming Serum is formulated with Nicotinamide Adenine Dinucleotide (NAD+), collagen extract, and peptides to help support skin elasticity and firmness. The full ingredient list includes Aqua, Glycerin, 1,2-Hexanediol, Carbomer, Arginine, Nicotinamide Adenine Dinucleotide, and Collagen Extract.
The formula is CPNP certified (Cert #20220116), free of high-concern ingredients, and suitable for all skin types.
Results build gradually with consistent use — this isn't an overnight formula, and we'd rather set that expectation honestly than promise a timeline we can't guarantee.
The formula is fragrance-free with a short, low-irritant ingredient list. If you're prone to reactions, patch test on your inner arm for two days before applying to your face.
Yes. It layers well with most routines. If you use strong actives like retinol or acids, apply this serum first on damp skin, then your other products.
Subscriptions ship every 30, 60, or 90 days — pause, skip, or cancel anytime. If you're not satisfied within 60 days of delivery, reach out for a full refund.
Most orders arrive within 7–14 days, with tracking sent by email once your label is created.
