Why Doesn’t Rejuvaskin Include SPF in Its Scar Products?

One of the most common questions we hear is:
“Why not just include SPF in scar gel?”

It sounds convenient—but when it comes to scar healing, combining the two actually reduces effectiveness.

Here’s the science behind why we keep them separate.

The Science of Scar Healing

Silicone gel is widely recognized as the gold standard for scar treatment.

It reduces the formation of hypertrophic and abnormal scars (Giorgi et al., 2009)
It works by forming a protective barrier that regulates hydration and supports proper healing (Bains & Kaur, 2023)

At the same time, UV exposure can worsen scars, leading to discoloration and delayed healing—so sun protection is essential (Monstrey et al., 2014).

You need both—but not combined.

Scar gels are formulated to deliver optimal silicone performance.

Silicone is most effective when applied consistently and as a dedicated treatment (Giorgi et al., 2009)

Adding SPF dilutes the formulation and reduces its ability to support scar remodeling.

Sunscreen is critical—but only when applied correctly.

UV protection is a key part of scar care but should be used alongside, not inside, treatment products (Monstrey et al., 2014)

Best practice:
Apply scar gel first → let dry → apply sunscreen over it

This ensures full protection without compromising healing.

Scar healing requires consistent, around-the-clock care.

But:

Keeping them separate allows proper use in both daytime and nighttime routines.

Rejuvaskin doesn’t include SPF in its scar gels because it would compromise both scar healing and sun protection.

Separate products = better results.
