Anti-Ageing Peptide Serum · 30ml
Some days, dry skin makes every little line seem more obvious. You want a softer, fresher look — and skincare that fits the routine you already enjoy.
YOUTHBOOST combines five peptides with glycerin and sodium PCA in a light, water-based serum. It hydrates to leave skin feeling supple and helps soften the appearance of fine lines caused by dryness.
Just two or three drops before your usual skincare. No new routine to learn. The smoothing effect of hydration is temporary; this is daily cosmetic care, not a promise to erase wrinkles.

For external use only. Keep out of reach of children. Store in a cool, dry place out of direct sunlight.
After cleansing and toning, apply Youth Boost before Pre-Eminent Beauty Serum. Use your Imperial Eye Gel as usual, then finish with Imperial Moisturiser in the morning or Night Elixir at night. SPF goes last in the morning.
Youth Boost is an optional peptide serum, not a replacement for your Four Phase collection. Moisture Burst is the extra-moisture option for skin that still feels dry. You do not need every serum: choose what suits your skin.

The serum itself is soft and light and smooth with a slightly glossy feel. It applies really easily to the skin and is absorbed quickly.

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.

Read the full refund terms ↗Hydration helps soften the appearance of fine lines caused by dryness, so skin looks smoother and feels more supple. This effect is temporary. Youth Boost contains peptides used in skincare for visible signs of ageing, but we do not promise wrinkle removal, permanent lifting or a fixed time for results.
Youth Boost is a thin, water-based peptide serum for a smoother-looking, more supple finish. Moisture Burst focuses on extra moisture, with ceramide NP, squalane and plant oils. Choose the one that fits what your skin wants; you do not need to add both.
One 30ml Youth Boost glass bottle with a dropper. Use two or three drops at a time, morning and evening. How long it lasts depends on how much you use.
The formula has no added fragrance, but any skincare product can cause a reaction. Check the ingredients and try a small area first. Stop if irritation occurs. Our team can help if you have questions before choosing.
Use Youth Boost after cleansing and toning, before Pre-Eminent Beauty Serum, because of its thin texture. Use Imperial Eye Gel as usual, then your day or night cream. Finish your morning routine with SPF. You can also use it before your existing moisturiser without owning Four Phase.
