Larens vs Nutrivi — what's the difference?

A shared foundation: Biopeptide Complex

Larens and Nutrivi are two separate brands belonging to WellU Group, but both grew out of the same scientific discovery — the patented marine collagen peptide complex, Biopeptide Complex. It consists of several hundred natural, biologically active peptides obtained from the skins of selected freshwater fish species, developed by the WellU Scientific Board over more than a decade.

So the difference between the brands lies not in the active ingredient itself, but in the form and route of delivery into the body.

Larens — cosmeceutics for topical use

Larens is a line of cosmeceutics — products that sit at the border of cosmetics and dermatology, with a higher concentration of active ingredients than classic drugstore cosmetics. They are applied directly to the skin of the face and body, and to hair, in the form of:

• Serums (e.g. Biopeptide Serum Spray) — the highest concentration of active ingredients, used as the base of a routine.
• Creams (e.g. Lifting Face Cream) — finish the routine, providing long-lasting hydration and a lifting effect.
• Sheet masks (e.g. BioRenew Tissue Face Mask) — a weekly intensive treatment, with a lifting effect lasting up to 7 days.
• Targeted sets (e.g. Beauty Intensive Duo) — combine several products for a comprehensive treatment.

Larens' effects are noticeable relatively quickly, because the active ingredients come into direct contact with the skin — effects such as hydration or smoothing are often visible after just a few uses, though full collagen regeneration is a process that takes weeks.

Nutrivi — supplements for internal use

Nutrivi is a line of dietary supplements taken orally — water-soluble powders or ready-to-drink beverages. Rather than acting on the skin locally, they support the body as a whole: joints, tendons, bones, hair, nails, immunity and energy levels.

• Glowin'UP — beauty from within: marine collagen peptides, hyaluronic acid, amino acids.
• MoveUP — support for physical activity and weight management.
• GetUP — energy and focus built on B vitamins.

The effects of Nutrivi supplementation are usually spread out over time — the body needs more time to absorb and use the ingredients than with topical application, but the effect is more comprehensive and reaches structures that cosmetics cannot access, such as joints or bones.

Larens and Nutrivi side by side — a quick comparison

Is it worth combining Larens and Nutrivi?

According to WellU materials, the best results come from combining both brands in a single routine — so that marine collagen peptides reach the body simultaneously from the outside (through the skin) and from within (through supplementation). The manufacturer describes this as a synergy effect: Larens skincare supports a visible, external effect, while Nutrivi builds it from the ground up, strengthening structures that cosmetics cannot reach — joints, tendons, bones.

A sample routine combining both brands might look like this:

• Morning: Biopeptide Serum Spray (Larens) on cleansed skin + Glowin'UP (Nutrivi) as a morning drink.
• Before/after training: MoveUP (Nutrivi) to support performance.
• Evening: Lifting Face Cream (Larens) to finish your skincare.
• Once a week: BioRenew Tissue Face Mask (Larens) as an intensive renewal treatment.
