Is aloe vera good for anti-aging?

1. Antioxidant & Photoprotective Effects

Free radical scavenging ability:

Aloe vera polysaccharides (e.g., acetylated mannans) have shown 70-80% DPPH free radical scavenging in in vitro experiments, close to that of vitamin C (85%) (Lin et al., 2019).

Polyphenols (e.g. aloe vera) in aloe vera reduce ultraviolet (UV)-induced oxidative damage and inhibit ROS (reactive oxygen species) generation in skin cells by up to 50% (Reuter et al., 2010).

Photoaging protection:

A double-blind trial of 60 photoaging patients showed a 33% reduction in skin roughness and a 28% reduction in UV spots after 8 weeks of use of a cream containing 0.5% aloe vera extract (Cho et al., 2015).

The β-carotene and vitamin E in Aloe Vera synergistically repair UVB-induced DNA damage and reduce collagenase (MMP-1) activity by 40% (Surjushe et al., 2008).

2. Hydration & Barrier Enhancement

Skin moisture content is increased:

Aloe vera polysaccharides (e.g. glucomannans) have been shown to increase stratum corneum water content by 25-30% in in vitro models, comparable to the effect of hyaluronic acid (Dal'Belo et al., 2006).

Clinical trials have shown an 18% reduction in transdermal water loss (TEWL) and a 45% improvement in dryness after 4 weeks of use of a formulation containing 10% aloe vera gel (Fox et al., 2014).

Barrier Repair Mechanisms:

Aloe vera upregulates the expression of filaggrin and claudin-1 in keratinocytes, strengthening the skin barrier (Lee et al., 2019).

3. Collagen & elastin synthesis (Collagen & Elastin Stimulation)

In vitro experiments:

Treatment of fibroblasts with Aloe vera polysaccharide (200 μg/mL) increased type I collagen synthesis by 50% and elevated elastin mRNA expression by 35% (Yagi et al., 2017).

Gibberellin (gibberellin) in Aloe vera promotes collagen deposition by activating the TGF-β signaling pathway (Choi et al., 2013).

Human trials:

A study in women aged 45-60 years showed a 22% improvement in skin elasticity and a 19% reduction in the depth of crow's feet after 12 weeks of daily topical application of a serum containing 1% lyophilized aloe vera powder (Kim et al., 2020).

4. Anti-Inflammatory & Anti-Glycation (Anti-Inflammatory & Anti-Glycation)

Inflammatory factor inhibition:

Sterols in Aloe vera inhibit IL-6 and TNF-α secretion and reduce inflammatory-aging (Vázquez et al., 1996).

In a rosacea model, Aloe vera extract reduced erythema by 47% (Pazyar et al., 2013).

Anti-Glycation:

Aloe vera polysaccharides inhibited the formation of advanced glycosylation end products (AGEs) and reduced the cross-linking rate of glycated collagen by 30% (Kumar et al., 2019).

5. Synergy with Other Anti-Aging Ingredients (Synergy with Anti-Aging Ingredients)

Vitamin C:

Aloe vera polysaccharides stabilize vitamin C (L-ascorbic acid) and prolong its antioxidant activity by 2-fold (Telang, 2013).

Retinol:

A combination of 0.1% retinol + 2% aloe vera gel reduces the irritating properties of retinol while increasing collagen density by 18% (Draelos et al., 2010).

Peptides:

Aloe vera in combination with palmitoyl tripeptide-1 synergistically stimulates fibroblast proliferation by 40% (Farwick et al., 2008).
