Every component in our formula is chosen to support your skin’s natural resilience — especially under the sun.

Polypeptides
These skin-loving chains help reinforce your skin’s moisture barrier, which plays a key role in defending against environmental stressors like UV rays and pollution. Healthy skin starts with a healthy barrier.

Squalane
A gentle hydrator that mimics your skin’s natural oils. Squalane helps maintain softness and prevent water loss — especially when skin is exposed to sun and heat.

Niacinamide (Vitamin B3)
Known for helping reduce the appearance of redness and uneven tone. Niacinamide supports skin hydration and barrier function — key after sun exposure.

Centella Asiatica
This botanical, prized for its calming and antioxidant properties, helps support skin that’s exposed to daily stressors like pollution and sunlight.

Paeonia Suffruticosa (Peony) Root Extract
Rich in natural antioxidants like paeoniflorin, this floral extract helps defend the skin against oxidative stress. It’s also known for helping promote a more even, radiant look.

At Borderline Beauty, we’re committed to reducing environmental harm. Our packaging uses recyclable PET bottles, and our formulas are made without ingredients linked to marine damage.
We avoid oxybenzone and octinoxate — two chemicals associated with coral bleaching — and all our sunscreens are 100% mineral-based.
They’re also microplastic-free, vegan, and designed with sensitive ecosystems in mind.
