Hydrates to soften the look of fine dryness lines.
Comfort for a dry-feeling neck and chest.
Leaves skin feeling smoother, softer and more supple.
When skincare stops at your jawline
Give your neck and chest a little love.
Your face gets all the care. But a dry-looking neck, fine lines and a chest that feels less smooth can be just as noticeable.
Radiant Décolletage brings that often-forgotten area into your routine. Hyaluronic acid and glycerin hydrate, while plant oils nourish for a softer, smoother-looking finish.
Use a little on your neck and upper chest, morning and evening. A simple way to enjoy skin that feels supple and cared for, right down to your neckline.

Where it fits · Morning and evening
Face routine as usual. Neck and chest, too.
After cleansing and toning · Before moisturiser
Take a small amount onto clean fingertips.
Gently smooth over your neck and upper chest with light upward strokes. Avoid pulling the skin.
Follow with your usual moisturiser. In the morning, finish with sunscreen on exposed skin.
Use morning and evening. This serum contains no SPF. Keep it away from eyes and irritated or broken skin.
Already using Four Phase?
Keep your face routine. Care for your neckline.
Use your Four Phase products on your face as usual. After cleansing your neck and chest, apply Radiant Décolletage there before your moisturiser. It is a targeted extra step for that area.
You do not need another full routine. Start with a small amount and let it absorb before getting dressed.
“I have been using the radiant décolletage for a while now and it certainly seems to be helping smooth the skin on my neck and chest so I will definitely continue buying it!”

From the HIGHBORN community
Read their experiences. Find what matters to you.
Customer reviews of Radiant Décolletage. Individual experiences vary.
A personal beginning
Care for the woman behind the routine.
During breast cancer treatment, Tracey found hope in her lifelong love of beauty. That hope grew into HIGHBORN, with a simple belief: feeling like yourself matters.
“Thank you for being a part of our story, for allowing us to be a part of yours.”
It hydrates to soften the appearance of fine lines caused by dryness. Skin can look smoother and feel more supple while moisturised. This is a cosmetic moisturising effect, not a promise to remove wrinkles or permanently lift loose skin.
What about age spots and uneven colour?
The formula includes a vitamin C derivative, liquorice root extract and kojic acid, ingredients used in brightening skincare. We do not promise that this serum will remove age spots or reverse sun damage. Its everyday focus is hydrated, smoother-looking skin. Use sunscreen on your exposed neck and chest.
What is included?
One 50ml glass jar of Radiant Décolletage neck and chest serum. Use a small amount morning and evening. How long it lasts depends on how much you use.
Is it suitable for sensitive skin?
The formula contains fragrant botanical oils and fragrance allergens. Natural ingredients can still cause reactions. Check the full ingredients, try a small area first and stop if irritation occurs. Do not apply to irritated or broken skin.
Where does it fit with Four Phase?
Keep your Four Phase face routine as usual. Apply Radiant Décolletage to your clean neck and upper chest before moisturiser, morning and evening. Finish with sunscreen on exposed skin in the morning. It is an extra step for your neckline, not a replacement for your face collection.
