Introducing SUNDONE: A Breakthrough in Sun Damage Repair & Skin Brightening

At Sweet Tox, we're always looking for advanced skincare backed by science to add to our Medical Grade line—and our newest launch is exactly that. Meet SUNDONE, a first-of-its-kind technology that works alongside your sunscreen to help prevent and reverse visible damage from everyday UV exposure. Isn’t that so cool!?

This advanced serum helps stop damage before it starts, while visibly improving the signs of aging and discoloration. Whether you’re dealing with dullness, uneven skin tone, or fine lines from long-term sun exposure, SUNDONE is here to change the game. 

So, What Makes SUNDONE Different?

Even with daily sunscreen use (which we always recommend!), your skin isn’t completely protected (ugh). UV rays can still sneak through causing subtle, long-term damage at the cellular level leading to dullness, dark spots, and premature aging. 

SUNDONE goes beyond surface protection to add a critical layer of defense and repair to protect and revive your skin from sun-related damage that accumulates over time. It's designed to work alongside your sunscreen by boosting both protection and repair!

Key Ingredients & What They Do:

ProteXidine™ 
A patented, proprietary antioxidant that acts like a decoy. It absorbs UV light before it reaches your skin cells, shielding your DNA and triggering enhanced repair. It also clears damaged cells and maintains healthy collagen for smoother, firmer skin. 

Hexylresorcinol 
A proven skin brightener that works especially well with exfoliants (think Vita-B Enzyme Polish or Dual Action Toner) to correct hyperpigmentation and enhance radiance. 

Arbutin 
A naturally derived brightening agent that evens skin tone and gently fades dark spots. 

Hexanoyl Dipeptide-3 
Speeds up the shedding of damaged skin cells, helping reveal a fresher, healthier-looking complexion. 

We know that these are big science-y names, but just trust us- this is the GOOD stuff.

What You’ll Notice:

  • Brighter, more even skin tone 

  • Reduced appearance of fine lines and wrinkles 

  • Fewer dark spots and discoloration 

  • Smoother, stronger, healthier-looking skin

Why It Matters:

Even with SPF, up to 8% of UV rays still reach your skin; enough to cause real damage you don’t see right away, including discoloration, collagen loss, and even skin cancer. SUNDONE helps fill in the gaps by defending your skin at a deeper level, and helping it bounce back faster. Think of it as backup for your SPF, and a boost for your glow!

Since we preach doing whatever we can to help prevent and reverse sun damage, we’re practicing that with SUNDONE 😉. 

How SUNDONE Fits Into Your Routine:

One of the best things about SUNDONE? It plays very well in the skincare sandbox! This formula is designed to work seamlessly with your existing routine- including powerhouse ingredients like Vitamin C, retinol, peptides, and hydrators. You don’t have to choose between protection and performance, because this product boosts both!

  • Pair it with Vitamin C in the morning for amplified antioxidant defense and a brightening boost.

  • Use it alongside retinol in the evening to support skin renewal and help calm the oxidative stress that can come with active ingredients.

  • Layer it under your moisturizer and SPF to round out a well-balanced, skin-protective routine.

You can even use this serum twice a day, meaning even better results!

The Bottom Line:

Whether you’re deep into a skincare routine or just beginning to take sun protection seriously, SUNDONE is the missing piece. It bridges the gap between protection and repair, supporting your skin at a deeper level while helping you glow from the outside in.
