Emerging serum formulas are shifting toward ingredients that focus on hydration, texture, tone, and general skin support. Three groups appear most often in new launches: polyglutamic acid, exosome-inspired blends, and new multi-peptide systems. Each offers a different approach and can fit into simple or advanced routines.

Polyglutamic acid is a humectant that binds water on the surface of the skin and supports a smoother feel. It works well as a hydration step after cleansing and before moisturizer. Many users pair it with hyaluronic acid or niacinamide because these combinations hold moisture and support routine stability. Polyglutamic acid serums can form the core of a simple hydration routine and are suitable across product lines. For commercial linking, The INKEY List Polyglutamic Acid Serum and similar K-beauty hydration serums are accessible to a wide audience.

A second group of products uses exosome-inspired or growth factor blends. These formulas use bioactive components that support texture, tone, and general skin quality through cell-signaling pathways. Evidence for these ingredients ranges from laboratory studies to small clinical evaluations, and regulatory conditions vary by region. Users often place these serums in night routines and avoid mixing them with strong exfoliants or concentrated retinoids on the same day. These products fit into higher-value routines and can attract users interested in premium formulations. Commercial examples include the Plated Skin Science Intense Serum and SkinMedica TNS Advanced+ Serum, both available through authorized derm retailers.

• The third trend involves new multi-peptide systems.

• Brands are combining signal peptides, carrier peptides, and hydrating bases to support lines, elasticity, and overall skin quality.

• These formulas integrate easily into both morning and evening routines because they pair well with hydrating and antioxidant products.

• Users place them after cleansing and before moisturizer or sunscreen.

• Multi-peptide systems work across a wide range of skin goals and create strong conversion potential due to broad demand and relatively stable pricing.

A simple way for users to choose between these options is to match the serum type to the primary skin goal. Polyglutamic acid supports hydration and routine consistency. Peptide systems support texture, lines, and elasticity. Exosome-inspired and growth factor formulas serve users exploring higher-value options for tone and general skin function. Each group can work as a standalone step or as part of a broader routine.

These emerging ingredients allow users to adjust routines based on climate, season, and personal goals. For Sage Beauty Studies, they offer strong commercial potential because they combine clear ingredient stories with measurable routine roles. You can link these products through affiliate programs used by retailers such as Sephora, Cult Beauty, Lookfantastic, Medik8, and brand-specific channels.                                                                           

                              *The Serums we Love *

1. The INKEY List Polyglutamic Acid Serum — Product Study 

This serum uses polyglutamic acid as a surface-level humectant that binds water and supports a smoother feel on the skin. The ingredient forms a film that helps retain hydration and works well in routines focused on moisture balance. The serum also contains supporting humectants that enhance its ability to hold water close to the skin.

The product fits users who want a hydration step that sits between cleansing and moisturizing. It pairs with hyaluronic acid, niacinamide, ceramides, and light moisturizers. It works in both morning and night routines and is suitable for simple or multi-step routines.

Apply to damp skin after cleansing. Follow with a moisturizer or sunscreen. Users often pair it with other hydrating serums for climate or seasonal transitions.

This serum works for most routine goals built around moisture retention, skin smoothness, or barrier support. It can also serve as the hydration step under active serums.

2. The Ordinary Multi-Peptide + HA Serum — Product Study

This serum combines several peptide complexes in a hyaluronic acid base. These peptides include signal peptides and support peptides associated with elasticity, firmness, and visible lines. The hyaluronic acid component supports water-binding and routine stability. The formula fits daily use in a broad range of routines because peptides generally work without irritation.

The serum supports users focused on lines, elasticity, and general texture improvement. It fits morning and night routines and pairs well with vitamin C, ceramides, niacinamide, and moisturizers. It does not require cycling and can be used year-round.

Apply after cleansing and before moisturizer or sunscreen. Users sometimes combine this serum with retinoids at night, though pairing should be adjusted to tolerance and routine complexity.

This serum is suitable for users who want measurable routine structure without committing to stronger actives. It also works as the main “treatment step” in simple routines.
