5 Benefits Of Allantoin For Skin, How To Use, & Side Effects

Trivia

Michele Francesco Buniva, an Italian physician, and Louis Nicolas Vauquelin, a French chemist, isolated allantoin for the first time in 1800.

What Is Allantoin?

Allantoin is a chemical ingredient and diureide of glyoxylic acid, often used to treat dry, rough, and itchy skin due to its moisturizing, skin smoothing, and wound healing properties (1),(2).

Allantoin also occurs naturally. Comfrey, a shrub that grows in some parts of Asia, North America, and Europe, is a reservoir of allantoin. The roots of comfrey contain allantoin and are often used to prepare ointments, creams, and lotions (3).

However, the comfrey plant contains toxins, which may cause serious side effects if used in its natural form. Luckily, its extracts are refined and processed in the labs to remove all toxins to make them suitable for cosmetic and skin care products (4).

Allantoin is also found in sugar beets, chamomile, wheat sprouts, and in certain types of bacteria and animals but not as abundantly as in comfrey.

Allantoin is white in color and odorless in its natural form.

1. Heals Wounds

Allantoin helps heal wounds, skin injuries, and scars faster. It stimulates the fibroblasts (cells that produce collagen) and boosts extracellular matrix synthesis. This helps re-establish normal skin on the wound site, making it less visible (5), (6). Comfrey extract may also help manage skin irritation. However, researchers concluded that it is because of the interaction of allantoin with other ingredients present in the extract (7).

2. Anti-Aging Benefits

A study showed that topical application of allantoin and other ingredients could improve skin texture and drastically reduce the appearance of wrinkles and fine lines (8). It also facilitates collagen synthesis, which gives your skin a youthful appearance.
