What the evidence says
Mostly mechanism / observational
Most Beta-Glucan (topical) studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from mixed-quality studies published 1998–2023 with a typical study size of 43 participants.

In placebo controlled studies with healthy volunteers, the pretreatment of skin with CM-glucan offered substantial protection against skin damage caused by a detergent challenge or UV-A irradiation. In addition, CM-glucan enhanced the renewal rate of the stratum corneum.
Yeast beta-glucan was modified to water-soluble carboxymethyl glucan (CM-glucan) for topical use
In placebo-controlled volunteer testing, CM-glucan pretreatment protected against detergent- and UV-A-induced damage and increased stratum-corneum renewal
Industry-affiliated (Mibelle) with no stated sample size — supportive but lower-certainty human evidence
Thirty-four patients (79%) had the BGC remain intact while the wound healed underneath, with excellent cosmetic results, minimal analgesic requirements, and no need for repetitive dressing changes.
This review focuses on antioxidant activity, anti-wrinkle activity, anti-ultraviolet light, wound healing, and moisturizing effect and skin permeation absorption of β-glucan.
β-glucans possess specific properties that could benefit overall skin health and prevent age-related signs, including soothing and antioxidant activities.

Recent review framing beta-glucan as a soothing, antioxidant, immune-interacting topical ingredient
Notes age-related/anti-inflammatory benefits in conditional language ('could benefit', 'promising'), not established clinical efficacy
Two co-authors are affiliated with an industry ingredient producer — a relevant conflict-of-interest signal
It also suppressed hyaluronidase (32%) and collagenase (33%) activities and, additionally, displayed antitumor activity, blocking the growth of Sarcoma 180 cells in a concentration-dependent manner.

In-vitro, a bacterial beta-glucan increased macrophage activity and superoxide scavenging (66% at 1 mg/mL)
It inhibited hyaluronidase (32%) and collagenase (33%) — the enzymes that degrade HA and collagen, the proposed anti-aging basis
Cell/enzyme-assay level only, with no skin or human endpoints — anti-aging relevance is mechanistic
In the clinical photographs, wrinkles around the treated eye were greatly decreased.

A single 59-year-old patient treated weekly for 12 weeks with a Jet-M device plus a multi-ingredient solution including beta-glucan; crow's-feet wrinkles decreased
Biopsies showed increased upper-dermis collagen, fibrillin-1, procollagen type 1, and tropoelastin
Anti-wrinkle effect cannot be attributed to beta-glucan — the formula also had copper-GHK, HA, rhodiola, and tranexamic acid plus a device (counter-evidence on thin anti-aging data)
