Platelet Derived Exosomes in Aesthetics Data, Safety, and Real World Use Cases

This protocol emerged from their post-ablative laser study. They observed that patients who had been using the product beforehand seemed to heal faster and have better results. Alisa calls it a 'little hack.' The idea is that exosomes put fibroblasts into a more active, regenerative state, so when the laser or needles create micro-injuries, the repair response is amplified. She stressed that it doesn't matter whether you use Intense or Calm for pre-treatment. Post-procedure, they recommend Calm, which is specifically formulated for compromised skin. The combination of pre- and post-treatment significantly reduces downtime—redness, inflammation, and the period before patients feel comfortable in social settings.

The post-ablative laser study, published in a peer-reviewed journal, showed that using Calm significantly reduced downtime—the period of redness, swelling, and social discomfort. Alisa noted that the product is water-based, so the rule of thumb is to wait until you can put water on your skin. This aligns with the general principle of not introducing products too early. The exosomes in Calm help modulate inflammation and accelerate the transition from the inflammatory phase to the proliferative phase of healing.

The hair study was conducted by Dr. Rod Warick, a plastic surgeon and researcher in Dallas. It was double-blind, placebo-controlled, and randomized, with tattooed measurement sites for consistency. The serum is pH-balanced for color-treated hair and non-greasy, so it can be applied and left in without washing. Alisa emphasized that hair follicles hate oxidative stress, and the anti-inflammatory, antioxidant properties of the exosomes create a better environment for growth. The crossover design showed that placebo patients who later received the serum had dramatic improvements. The product is a different formulation from the facial serums, with additional ingredients to support hair, but the hero ingredient is the same platelet-derived exosomes.

Alisa stressed this as the most critical tip for success. She shared that she used to use Neutrogena wipes with oil, not realizing the oil would break down the exosomes. The lipid bilayer is essential for protecting the exosome's cargo; once disrupted, the contents leak out and are no longer functional. She compared it to leaving probiotics out of the fridge—they just die. The 5-minute wait allows the water-based serum to absorb and the exosomes to begin interacting with the skin before being covered by other products. This rule applies to all products in the line, including the hair serum (though hair application is less likely to be layered immediately).

Alisa explained that exosomes are like text messages to cells. The platelet-derived exosomes they isolated carry a specific 'repair, renew, regenerate' signal. Using electron microscopy, they saw the exosomes penetrating to the reticular dermis, likely via hair follicles. Once inside the cell, the exosome delivers its cargo and then exits—described as 'very polite.' This transient, intracellular delivery avoids the constant, potentially problematic signaling of growth factors. The ability to reach the reticular dermis means they can influence fibroblasts and other structural cells, which aligns with the biopsy-proven collagen and elastin improvements.

The 12-week study included punch biopsies of treated and untreated skin. Histological analysis showed profound changes in collagen and elastin. Alisa specifically highlighted the 80-year-old's result to emphasize that age is not a barrier. She noted that the degree of improvement correlated more with photodamage than with chronological age—those with more sun damage saw greater results. This suggests that the exosomes are addressing accumulated damage rather than just providing a temporary plumping effect. The finding has motivated the company to position the product as a true regenerative tool, not just a cosmetic.

Alisa described this as a 'little hack' learned from their post-laser studies. By pre-treating for a couple of weeks, the fibroblasts are 'revved up' and more able to respond to the controlled injury of a laser or microneedling. This leads to a better final outcome. She emphasized that it doesn't matter which product (Intense or Calm) is used for pre-treatment. The post-procedure product, Calm, is specifically formulated for the compromised skin barrier, and they saw reduced downtime and redness. The combination of pre- and post-treatment creates a comprehensive regenerative protocol.

Alisa stated clearly that they do not believe exosomes need to be microneedled in, and she 'actually wonders if it damages them.' Because exosomes have a delicate lipid bilayer, the physical force of needles could rupture them, releasing their contents prematurely and rendering them ineffective. Since their product is water-based, the standard rule is to wait until the skin can tolerate water (usually a few hours to the next day) before applying. She noted that if you've pre-seeded the skin for two weeks, the timing of post-procedure application (an hour later vs. the next day) doesn't matter much. This approach prioritizes exosome integrity over forced penetration.
