Rituo: which skin types is it suited to, and how many sessions are needed?

Rituo is a skin booster made by specially processing donated human skin to remove cells and immune-reactive components while retaining dermal structures such as collagen and elastin. This acellular dermal material is processed into fine particles for injection.

While familiar fillers fill empty spaces with a particular substance, Rituo takes a different approach by implanting material with a structure similar to skin itself.

The material was originally a graft used for many years in reconstructive surgery, such as burn treatment and breast reconstruction, before its use expanded to cosmetic injections.

Cell and animal studies report stimulation of fibroblasts to help produce collagen and hyaluronic acid. These are still cell and animal findings; effects of repeated, divided skin-booster injections in humans require separate confirmation.

The most common question concerns the difference from Rejuran.

Rituo uses human-derived acellular dermal material, while Rejuran uses a salmon-derived ingredient (PN). Both act in the dermis, but their raw-material origins differ.

Rejuran is closer to inducing cellular recovery signals. Rituo introduces a skin-like structural material that acts as a scaffold into which surrounding cells can grow.

There are not yet direct comparative data sufficient to conclude that one is better.

Rituo’s approach may fit visibly volume-deficient areas, while Rejuran is more commonly familiar for skin texture or overall tone improvement.

During consultation, we choose one according to the concern, or consider combining them depending on the condition.

In clinical experience, it is recommended relatively often to people who feel their dermis has thinned and lost elasticity, or are concerned about hollow-looking cheeks or temples.

Its scope is broader when pressing the skin clearly reveals thinness and reduced elasticity than when fine wrinkles alone are the concern.

For thin, sensitive areas around the eyes or mouth, smaller-particle products are selected rather than using large particles unchanged.

Thin skin is not automatically excluded, but the suitable form differs by area, so skin thickness and condition must first be assessed.

Some report noticeable change after the first session, but results more often develop as responses accumulate over several sessions.

There is no fixed formula: skin condition, the area of concern, and other combined procedures can change the plan. The principle is to monitor and adjust during consultation.

It is worth knowing beforehand that local reactions may be more common with Rituo than with conventional fillers.

Related research reported more pain, swelling, and heat at the treatment site than the comparator, but most reactions were mild and settled naturally within 1 week.

These are generally managed with cold compresses or prescribed pain medication.

Human-derived material requires an aseptic treatment environment for infection control. Consultation is essential beforehand if you have autoimmune disease or a coagulation disorder, or are pregnant or breastfeeding.

Some product families also contain porcine-derived ingredients, so disclose any related allergies beforehand.

For people who feel their dermis has thinned and lost elasticity, or whose clear volume loss needs structural support, I have often found structural dermal reinforcement more suitable than a simply hydrating skin booster.

If you are sensitive to immediate swelling or pain, or want only modest texture improvement, another method may feel more comfortable.

I believe the nature of the concern should come before revenue when recommending a procedure.

If I judge it unsuitable, I explain other methods first, and decide the direction after assessing skin thickness, the area of concern, and treatment history (individual results vary).
