Which Serums Belong in a Morning and Night Skincare Routine?

For a Renoviq London routine, use NAD+ — Cellular Energy Serum in the morning. PDRN — Polynucleotide Repair Serum suits both morning and evening use. At night, use GHK-Cu — Copper Tripeptide Firming Serum and RETINAL — Overnight Renewal Serum, as both are designated for PM use. This creates a simple timing framework: NAD+ in the AM, PDRN in the AM or PM, and GHK-Cu plus RETINAL in the PM. Choose your serum timing first, then keep the rest of your routine consistent.

Morning routine: NAD+ and PDRN

The morning options are NAD+ — Cellular Energy Serum and PDRN — Polynucleotide Repair Serum. NAD+ is designated for AM use, making it the dedicated morning serum in the Renoviq London collection. It contains 3% nicotinamide riboside and comes in a 30 ml format. PDRN is designated for AM/PM use, so it fits naturally into a morning routine when that timing suits your preference. This 30 ml serum contains 3% polynucleotides (PDRN). A straightforward morning structure is to select NAD+ as your AM-specific serum, or choose PDRN when you want its flexible AM/PM placement. Keep the routine focused: morning is the time for products explicitly marked AM or AM/PM, while PM-designated formulas remain for the evening. This simple division makes it easier to maintain a regular skincare schedule without second-guessing when each serum belongs.

Night routine: GHK-Cu and RETINAL

The evening serums are GHK-Cu — Copper Tripeptide Firming Serum and RETINAL — Overnight Renewal Serum. Both are designated for PM use, so they belong in a night routine rather than a morning one. GHK-Cu contains 3% copper tripeptide-1 (GHK-Cu), is supplied in a 30 ml size and has firmness as its stated axis. RETINAL contains 0.1% retinaldehyde, also in a 30 ml size, with renewal as its stated axis. Use the PM designation as the deciding factor when planning your evening routine. PDRN can also be used at night because its use is listed as AM/PM. This gives the evening category three possible Renoviq London serum choices: GHK-Cu, RETINAL and PDRN. The key distinction is clear: GHK-Cu and RETINAL are night-only by designation, while PDRN remains flexible across both parts of the day.

A simple way to organise your serum timings

Start by separating the collection into three timing groups. The first group is AM: NAD+ — Cellular Energy Serum. The second group is AM/PM: PDRN — Polynucleotide Repair Serum. The third group is PM: GHK-Cu — Copper Tripeptide Firming Serum and RETINAL — Overnight Renewal Serum. This approach keeps the decision practical and based on each serum’s stated use. If you prefer a minimal morning routine, NAD+ provides the AM option. If you want one serum that can sit in either routine, PDRN provides that flexibility. For the evening, select from the PM-designated GHK-Cu and RETINAL formulas, with PDRN also available for night use. Renoviq London positions its range around single-active serums for home use, which makes the use designation a useful first reference point. You do not need to turn timing into a complicated system: AM, AM/PM and PM labels provide the essential structure.

Choosing between flexible and time-specific serums

A serum’s listed use tells you whether it is specific to one routine or flexible enough for both. NAD+ is time-specific for the morning, while GHK-Cu and RETINAL are time-specific for the evening. PDRN is the flexible option because it is designated for AM/PM use. This distinction is useful when you are building a routine around your preferred schedule. A person who keeps skincare to the morning can choose from the AM and AM/PM categories. A person who focuses on an evening routine can choose from the PM and AM/PM categories. For a two-part routine, the range offers clear placement across both times of day. The product names also reflect their stated axes: firmness for GHK-Cu, repair for PDRN, renewal for RETINAL and energy for NAD+. Timing remains the practical guide: follow the AM, AM/PM or PM designation shown for each formula.
