Alpha-lipoic acid is extensively used in skincare and cosmetology owing to its perceived anti-aging properties. Some research suggests it can make your skin glow and feel smooth in the following ways:

  • Protects Against Free Radicals

As it is a powerful antioxidant, alpha-lipoic acid neutralizes harmful free radicals(1). Free radicals could damage your skin.

  • Delays The Signs Of Aging

Alpha-lipoic acid may delay the appearance of facial aging (2). In another study, alpha-lipoic acid dispersions were found to reduce fine lines and wrinkles and promote skin texture in volunteers (3).

  • Makes Your Skin Visibly Radiant

Topical application of beauty products with alpha-lipoic acid may improve your skin’s overall health, wellness, and appearance. By fighting against the signs of aging, dark spots, and exposure to environmental pollutants and even sun damage, alpha-lipoic acid can make your skin visibly clearer and smoother.

protip_icon Quick Tip
Alpha lipoic acid is an organosulfur (a compound containing organic sulfur) derived from caprylic acid.
  • May Protect Against UV Rays

Anecdotal evidence suggests that alpha-lipoic acid may protect your skin from ultraviolet (UV) rays. This benefit could be attributed to the acids antioxidant properties.

  • Soothes And Nourishes Dry Skin

Dry skin is more prone to damage and needs intensive care to look healthy and nourished. Using alpha-lipoic acid on dry skin may make it soft, smooth, and supple. However, more research is warranted in this regard.

  • May Reduce Skin Damage From Smoking

Smoking can cause oxidative stress that damages your skin (4). It is believed that topical application of alpha-lipoic acid may help reduce this damage.

  • Could Be Suitable For Sensitive Skin

Alpha-lipoic acid is good news for those with sensitive skin. It seldom irritates your skin or causes redness or breakouts.

  • May Reduce Stretch Marks

Alpha-lipoic acid (LA) holds promise in enhancing the appearance of stretch marks to some extent due to its positive effects on collagen synthesis in the skin. A study revealed that it promotes collagen production, especially type 1 collagen, in the dermal fibroblast cells by triggering the collage-processing enzymes. Type 1 collagen is an essential component of the skin structure and plays a crucial role in maintaining its elasticity and resilience (5). Moreover, the topical application of ALA may promote wound healing and reduce the risk of scarring, especially burn scars (6). These findings suggest that ALA may have applications in improving skin quality, potentially aiding in the reduction of stretch marks.

We now know the benefits of alpha-lipoic acid for the skin. But is it suitable for everyone? Find out below.

Yes, alpha-lipoic acid is gentle enough to be used on any skin type.

If you want to revitalize your skin, improve its texture, fight acne, or prevent premature signs of aging, alpha-lipoic acid is exactly what you need. Its antioxidant and anti-inflammatory properties soothe your skin and reduce acne symptoms.

Anecdotal evidence suggests that regular use of alpha-lipoic acid might help manage hyperpigmentation and inflammation. This gentle and beneficial ingredient is something people with all skin types can benefit from.

That said, could alpha-lipoic acid have any adverse effects too? Let us understand the same in the next section.

Potential Side Effects Of Using Alpha-Lipoic Acid

Alpha-lipoic acid is generally considered safe and gentle with a low risk of side effects. However, since it is a detoxifying enzyme, it may cause your skin to purge during the initial use and lead to breakouts. Do not worry if this happens as the purging stops within a few days of initial use.

When taken in the recommended doses, it rarely causes any adverse effects. But if taken in higher doses, it may lead to symptoms like nausea or rashes. These effects could be more pronounced in the elderly (7). Extremely high doses may lead to oxidation, though there is no research to support this. Some products with a high concentration of alpha-lipoic acid may lead to redness or skin irritation.

If you are new to it, it is recommended you incorporate alpha-lipoic acid gradually into your skincare routine. Pregnant women and children should consult a healthcare provider before taking this antioxidant.

As a skincare ingredient, alpha-lipoic acid is extremely versatile. It is both water- and fat-soluble and can be consumed in the form of supplements or applied topically in the forms of creams and gels.

While alpha-lipoic acid is made in the human body, it is produced only in minute quantities. Some foods may also contain this acid. But supplementation is believed to be the best way of optimizing its intake. It is best to take an alpha-lipoic supplement on an empty stomach.

For those looking to incorporate alpha-lipoic acid in your skincare routine through topical application, you can go for a cream, gel, moisturizer, or a serum containing the ingredient after consulting your doctor.
