What Is Growth Factor Sunscreen?
The primary ingredient in Sonrei's facial line is kinetin. Kinetin is a plant-derived cytokinin originally studied for its anti-aging potential in skin. It helps improve the appearance of photodamaged skin without the irritation commonly associated with retinoids. This makes it an ideal candidate for daytime routines where sensitivity is a concern.
How Kinetin Works on Skin
Kinetin functions by signaling skin cells to retain moisture and improve overall texture. In a 24-week clinical study, topical application of 0.1% kinetin showed measurable improvements in skin's ability to retain moisture. The study also noted a reduction in hyperpigmentation and brown spots over time.
Unlike synthetic growth factors, kinetin is derived from plants. This natural origin contributes to its gentle profile. It layers well alongside other active ingredients like retinoids. Because it does not typically increase sun sensitivity, it fits seamlessly into a morning routine that includes broad-spectrum SPF.
Benefits for Skin Appearance
Users of growth factor sunscreens often report a smoother, more even skin tone. The combination of UV protection and kinetin addresses two major causes of dullness: existing damage and new exposure. By preventing further breakdown of collagen, the formula helps maintain skin firmness.
Sonrei's Sea Clearly SPF 35 is designed to be invisible on all skin tones. It dries down completely clear, leaving no white cast. This transparency is crucial for daily compliance. When a sunscreen feels like a hydrating primer rather than a heavy cream, users are more likely to wear it consistently. Consistency is the key to seeing long-term improvements in skin health.
Integrating Into Your Daily Routine
Applying growth factor sunscreen is the final step in a morning skincare routine. It should be applied after serums and moisturizers but before makeup. The formula acts as a primer, allowing foundation to grip without pilling. Wait about 60 seconds for the gel to set before applying additional products.
For those with sensitive skin, Sonrei offers Clearly Zinq SPF 35. This 100% mineral formula provides the same growth factor hydration benefits with a soft natural finish. It is ideal for reactive skin that may not tolerate chemical filters. Choosing the right base ensures that the growth factors can work effectively without causing irritation.
