Aloe vera has been used for centuries as a natural skincare remedy. While you might know it best for soothing sunburns, research shows this succulent plant offers numerous benefits for facial skin health.

In this evidence-based article, we’ll explore how aloe vera can improve your facial skin and the science behind its effectiveness.

How Aloe Vera Benefits Your Skin

Aloe vera contains several compounds that benefit your skin, including vitamins, minerals, enzymes, and polysaccharides. These components work together to provide multiple skin benefits.

Research shows aloe vera possesses remarkable antioxidant and anti-inflammatory properties that can help prevent skin aging and improve overall skin condition (1).

Let’s look at the specific ways aloe vera can benefit your facial skin.

Improves Skin Hydration and Moisture Retention

One of aloe vera’s most significant benefits is its ability to hydrate skin. Research has demonstrated that applying aloe vera extract topically increases skin hydration.

A clinical study found that cosmetic formulations containing aloe vera extract increased water content in the stratum corneum (the outermost layer of skin) after application (2).

A comprehensive review found that aloe vera leaf gel is among several botanical extracts that can improve skin barrier function when applied to the skin. These improvements might include better moisture retention, increased hydration, or healthier skin cell development (3).

Together, these studies suggest that aloe vera is effective for improving skin hydration and helping maintain a healthy moisture barrier.

Tip
For maximum hydration benefits, apply aloe vera gel to slightly damp skin. This helps lock in additional moisture and enhances the hydrating effects.

Boosts Collagen Production and Skin Elasticity

As we age, skin naturally loses collagen and elasticity. Research suggests aloe vera may help combat these effects.

A 12-week, double-blind, randomized controlled trial found that daily intake of aloe sterol (a compound found in aloe vera) significantly reduced transepidermal water loss and increased collagen score compared to placebo. The study also showed improved skin condition, including reduced facial redness (4).

Another study evaluated the effects of oral aloe sterol supplementation on skin elasticity and hydration. The results showed statistical differences in skin moisture, elasticity, and collagen score between aloe sterol and placebo groups. Ultrasound analysis revealed increased collagen content in the dermis with aloe sterol intake (5).

These studies suggest that consuming aloe sterol supplements may help maintain skin elasticity and stimulate collagen production, contributing to healthier, more youthful-looking skin.

Reduces Inflammation and Redness

If you struggle with skin redness or irritation, aloe vera’s anti-inflammatory properties may help.

A randomized, double-blind, placebo-controlled study tested a highly concentrated aloe vera gel (97.5%) on UV-induced skin redness. The researchers found that aloe vera significantly reduced UV-induced erythema (redness) after 48 hours, with effects superior to 1% hydrocortisone in placebo gel (6).

Another study comparing different plant extracts for anti-inflammatory effects found that aloe vera showed significant anti-inflammatory effects on UV-induced erythemas compared to controls (7).

Overall, these studies indicate that aloe vera is effective at reducing skin inflammation and redness, particularly when it comes to UV-induced skin irritation.

Protects Against and Treats UV Damage

UV radiation is a major cause of premature skin aging and damage. Research suggests aloe vera may help protect against and treat UV-induced skin damage.

A study comparing baby (one-month-old) and adult (four-month-old) aloe vera shoot extracts found that the baby aloe extract better protected skin cells from UVB-induced damage. The extract suppressed matrix metalloproteinases (enzymes that break down collagen) and elevated type I procollagen levels, suggesting it could protect skin from UV damage more effectively than adult aloe extract (8).

A review of plant extracts that protect against UVA radiation identified aloe vera among several plant extracts with protective benefits. These natural compounds not only absorb UV photons but also possess additional protective properties like antioxidant and anti-inflammatory effects (9).

A clinical trial testing a multi-plant product containing aloe vera gel showed improvements in skin photoaging, including enhanced skin hydration, elasticity, and reduced melanin levels. The beneficial effects were linked to antioxidant and anti-tyrosinase activities (10).

Together, these studies suggest that aloe vera has significant potential to protect against and help repair UV-induced skin damage, particularly through its antioxidant and anti-inflammatory properties.

Note
While aloe vera may help protect against and treat UV damage, it shouldn’t replace sunscreen. For complete sun protection, use a broad-spectrum sunscreen in addition to any aloe vera products.

Helps With Hyperpigmentation

If you struggle with dark spots or uneven skin tone, aloe vera might help. Research indicates certain aloe species can address skin hyperpigmentation issues.

A comprehensive review of plants used for skin care in South Africa identified six aloe species that have been scientifically validated for their effectiveness in addressing skin hyperpigmentation problems (11).

A clinical trial found that liposome-encapsulated aloe vera gel extract significantly reduced the severity of melasma (a type of hyperpigmentation) in pregnant women compared to standard aloe vera gel, showing promise for addressing pigmentation concerns (12).

These findings suggest that aloe vera, particularly in enhanced delivery systems like liposomes, may be effective for addressing certain types of hyperpigmentation.

Provides Antioxidant Protection

Free radicals from pollution, UV radiation, and other sources can damage skin. Aloe vera’s antioxidant properties may help protect against this damage.

A study found that daily consumption of aloe vera gel extract significantly increased plasma total antioxidant capacity in healthy volunteers, suggesting systemic antioxidant benefits (13).

Research on medicinal plants found that aloe vera contains beneficial antioxidants. These protective compounds may help prevent aging-related disorders by fighting harmful oxidative stress in the body (14).

These studies suggest that aloe vera’s antioxidant properties may provide protection against oxidative damage both when applied topically and when consumed orally.

Advances in Aloe Vera Formulations

Recent technological developments have improved how aloe vera can be delivered to skin.

Researchers have successfully developed tiny carriers called nanoparticles that can deliver aloe vera to the skin more effectively. This advanced technology helps improve how well skin can absorb plant ingredients by enhancing their solubility, stability, and permeability. Similar plant-based nanoparticle formulations have shown improved moisturizing and protective benefits for the skin (15).

These advancements suggest that future aloe vera skincare products may offer even better results through enhanced delivery systems.

How to Use Aloe Vera on Your Face

Based on the research, here are some effective ways to incorporate aloe vera into your facial skincare routine:

1. Fresh Aloe Vera Gel

You can extract gel directly from an aloe vera leaf. Simply cut open the leaf, scoop out the clear gel, and apply it to your clean face. Leave it on for 15-20 minutes before rinsing with cool water.

2. Commercial Aloe Products

Look for high-concentration aloe vera products (90%+ aloe vera) with minimal additives. The research on anti-inflammatory effects used a 97.5% aloe vera gel concentration, which showed significant benefits (6).

3. Aloe-Infused Moisturizers

Research shows that skin products containing aloe vera extract can improve skin hydration, with timing dependent on concentration. Products with higher amounts of aloe (0.25% and 0.50%) increased skin moisture after just one application, while products with a lower concentration (0.10%) needed two weeks of regular use to show similar benefits (2).

4. Oral Supplements

Studies show benefits from consuming aloe vera orally. Aloe sterol supplementation has been shown to improve skin elasticity, hydration, and collagen content (5).

Tip
For best results, apply aloe vera to clean skin. If using fresh aloe, refrigerate the unused portion in an airtight container for up to one week. Consistency is key—studies showing benefits typically applied treatments daily for several weeks.

Potential Side Effects and Considerations

While aloe vera is generally safe for most people, there are some considerations to keep in mind:

Some individuals may experience allergic reactions to aloe vera. Always do a patch test before applying it to your face, especially if you have sensitive skin or a history of allergies.

Pure aloe vera gel has minimal side effects, but commercial products might contain additives that could cause irritation. Look for products with simple ingredient lists.

If you have specific skin conditions, consult with a dermatologist before incorporating aloe vera into your skincare routine.

Warning
While topical aloe vera is generally safe for facial use, you should avoid applying it to open wounds or deep cuts. If you experience irritation, redness, burning, or stinging after application, discontinue use immediately and rinse with cool water.

Conclusion

Scientific research supports multiple benefits of aloe vera for facial skin care. From improving hydration and boosting collagen production to reducing inflammation and protecting against UV damage, aloe vera offers many advantages for skin.

Whether you choose to use fresh aloe vera gel, commercial aloe products, or supplements containing aloe compounds, this natural ingredient can be a valuable addition to your skincare routine.

Remember that consistency is key—the studies showing significant benefits typically applied treatments daily for several weeks. With regular use, aloe vera may help you achieve healthier, more radiant skin.
