The details behind your ritual

A vitamin C serum and moisturizer set, in two steps

A serum and a moisturizer is the smallest routine that's still a routine. The Starter Duo puts Vitamin C Serum, with L-ascorbic acid and ferulic acid, underneath Peptide Moisturizer, a daily face cream with glycerin, aloe and a copper-based complex. Two bottles, the full ingredient lists, and the order they go on.

The Starter Duo: your questions, answered.

Can I use a vitamin C serum and a moisturizer together?

Yes, and this set is built for exactly that. Apply Vitamin C Serum first to clean, dry skin, let it absorb, then finish with Peptide Moisturizer on the face and neck. Follow the Vitamin C label and avoid sun exposure after use. Neither product is a sunscreen.

Is The Starter Duo a good skincare set for beginners?

It's our smallest routine and the easiest one to keep going: one serum, one moisturizer. If you later want a cleanser or an evening step, The Morning Ritual and The Evening Edit add one. Check both ingredient lists first if you have known sensitivities. The Vitamin C Serum contains fragrance.

What's in The Starter Duo?

2 full-size products: Vitamin C Serum (30 ml / 1 fl oz), Peptide Moisturizer (50 ml / 1.7 fl oz). Each can also be bought on its own.

In what order do I use The Starter Duo?

1. Vitamin C Serum: Morning, on clean skin. 2. Peptide Moisturizer: Morning and night, to finish. Follow each product's label directions.

How much is shipping on The Starter Duo?

US shipping is free on orders of $60 or more, which this set qualifies for. Allow about 5–9 business days in total. Items may arrive in separate parcels, each with its own tracking.

Can I return a set?
