REJURAN Turnover Ampoule Dual Effect: PDRN renewal and deep hydration combined

The dual mechanism: PDRN and hyaluronic acid working together

REJURAN Turnover Ampoule Dual Effect 30ml combines PDRN (polydeoxyribonucleotide) and high-concentration hyaluronic acid in a single ampoule. These two actives address adjacent dimensions of skin quality: PDRN activates fibroblast renewal through adenosine A2A receptor stimulation, triggering collagen and elastin production. Hyaluronic acid provides immediate and deep hydration through its ability to bind up to 1000 times its weight in water. Together, they work on both the structural (collagen, elastin) and moisture (water content) dimensions of skin quality — two factors that determine whether skin looks youthful or aged, regardless of the presence or absence of specific skin conditions.

How the Dual Effect Ampoule fits in a REJURAN routine

In a full REJURAN routine, the Dual Effect Ampoule occupies the same position as the Healer Turnover Ampoule — applied after the Rebalancing Toner and before the Nutritive Cream. The difference is the secondary focus: the Healer Ampoule maximises PDRN renewal stimulus, the Dual Effect Ampoule balances PDRN renewal with hydration recovery. This makes the Dual Effect more appropriate for evenings following an intensive skin day (heavy SPF, outdoor exposure, exercise) when the skin has depleted both its structural reserves and its moisture content, and a single product addressing both is more efficient than two separate actives.

Layering the ampoule with the REJURAN Nutritive Cream

REJURAN Healer Nutritive Cream 50ml is formulated to seal and amplify ampoule actives. Applied after the Dual Effect Ampoule absorbs (90-second wait), the Nutritive Cream provides a rich, nourishing moisture layer that extends the hyaluronic acid from the ampoule with additional emollient and barrier-supportive compounds. For the PDRN dimension, the cream's occlusive properties extend ampoule contact time with the skin overnight, which improves the cellular uptake of remaining PDRN fragments. The pairing creates a layered treatment where the ampoule drives the active work and the cream maximises the conditions for that work to complete.

Results across the first four weeks of use

The hyaluronic acid dimension of the Dual Effect Ampoule produces the fastest visible results: within one to two weeks of consistent nightly use, skin feels significantly more plump and supple, and fine lines that are dehydration-based appear visibly shallower. The PDRN dimension operates on a slower timeline: fibroblast response to PDRN activation builds over four to eight weeks before structural improvement is visible. At the four-week mark, skin typically shows both the fast hydration improvement from HA and the early stages of the structural improvement from PDRN — a combination that makes the overall skin appearance noticeably improved compared to a pure-hydration or pure-PDRN product at equivalent timeframes.

How to choose between REJURAN ampoule variants

REJURAN offers the Healer Turnover Ampoule (pure PDRN, maximum renewal stimulus) and the Dual Effect Ampoule (PDRN plus hyaluronic acid, balanced renewal and hydration). The Healer is the right choice for skin with established structural aging concerns where intensive PDRN stimulus is the priority and separate hydration is handled by other products. The Dual Effect is the right choice for skin that is both losing structural quality and is dehydrated, where a combined treatment addresses both dimensions without requiring two ampoule-weight products in the same routine. For most routines, alternating between both — Healer three nights, Dual Effect three nights — covers both dimensions throughout the week.
