How do scar creams generally work?

Scar creams typically have properties that reduce tension on the scar by:

  • providing moisture to soften the upper layer of the skin
  • providing a protective barrier to retain moisture
  • helping cells to regenerate and remodel the connective tissue below the scar

Some scar care products additionally protect against photo damage to the sensitive skin on the scar.
To find out what’s in your scar care product of choice, have a look at the typical ingredients that provide these functions.

Ingredients providing skin moisture and elasticity

The most effective way to prevent scarring is to keep freshly healed skin moist[2,3]– so many topical skin products contain ingredients to help with this process.

While certain ingredients, such as glycerin, lecithin, and propylene glycol draw in water molecules, others lock in the moisture by forming an oily layer on the skin.

Typically, silicones, petrolatum, lanolin, and mineral oil are used to lock in the moisture. Silicone additionally also reduces collagen overgrowth, which makes it one of the most effective ingredients for reducing scarring and the appearance of scars.

Dimethicone is a type of silicone with occlusive and moisturising properties that is used to promote faster healing and protect the skin during the night and is frequently used in moisturisers[4].

Panthenol, a vitamin B-5 derivative, locks moisture into the skin, providing elasticity while stimulating fibroblast growth, which helps new tissue formation[5]. It has been shown to improve scar appearance[6].

 

Ingredients that soften the skin

Typical skin softening ingredients are urea, alpha hydroxy acids such as lactic, citric, or glycolic acid, and allantoin[7]. These ingredients soften the keratin protein in our skin – which gives our skin its rigidity and holds the outer layer of our skin together. These ingredients slough off dead skin cells, break down inflamed scar tissue and encourage healthy cell growth.

This helps the skin retain more water and leaves the skin feeling smoother and softer, which reduces the tension and appearance of scars.

Ingredients to protect against sun damage and to improve skin tone

Antioxidants, such as vitamins A, C and E (sometimes as tocopherol), protect the skin against photo damage[8,9], while skin brightening agents, such as vitamin C, directly improve the skin tone[10]. Rosehip oil combines both properties as it is rich in vitamins A and C and, therefore, helps protect the sensitive skin of fresh scars and improves their appearance.

In addition to these, a sunscreen may be advisable as the skin on scars is particularly sensitive to the sun[1,2]. Indeed, it is highly recommended to protect young scars from the sun for around 18 months[11,12].

 

Ingredients to help skin remodeling and improve the appearance of scars

Hyaluronic acid has a unique ability to retain water, has anti-oxidative properties, and is a stimulant for collagen production[13,14]. As a result, it acts as a filler and helps to even out the skin. It naturally occurs in the body where it is involved in many processes, including wound healing and tissue repair[13,15].

Tripeptides, such as copper peptide, possess anti-inflammatory properties and are known to promote skin remodeling[16,17].

Onion extract contains the flavonoids quercetin and kaempferol, which regulate fibroblast activity, and has anti-inflammatory properties[18,19]. It has been clinically shown to improve the look and feel of scars[20].
