Frequently Asked Questions
Yes — the Light Heart Growth Serum is safe to use during pregnancy and breastfeeding. Our formula is 100% prostaglandin free and relies on a gentle, clinically studied peptide blend, making it one of the safest lash and brow serums available.
Each bottle contains 3ml of serum. With twice-daily use it lasts approximately 1 month up to 2 months with once-daily application. We recommend using within 12 months of opening.
Most customers notice fuller, longer lashes and brows within 4–6 weeks of consistent use. For best results, apply once or twice daily to clean, dry lashes and brows and use continuously.
Yes — the Light Heart Growth Serum is completely safe to use alongside lash extensions. Apply a thin layer to the root of your natural lashes using the doe foot applicator. Avoid contact with extension bonds or adhesive.
Yes. Our formula is prostaglandin analogue free and designed specifically for sensitive eyes, including contact lens wearers. As with all eye-area products, avoid direct contact with the eyes themselves.
No — it is 100% prostaglandin and prostaglandin analogue free. Instead of prostaglandins, we use a patented peptide blend (Biotinoyl Tripeptide-1 and Acetyl Tetrapeptide-3) clinically shown to stimulate lash and brow growth without the side effects associated with prostaglandin serums, such as iris pigmentation or eyelid darkening.
Yes — the Light Heart Growth Serum works on both lashes and brows. Apply along the brow line with the doe foot applicator morning and/or evening for fuller, denser brows. Most customers see visible brow improvement within 4–6 weeks.

The Light Heart Growth Serum is manufactured in the UK to the highest cosmetic standards and is internationally compliant for personal use and retail worldwide.
Our soft doe foot applicator holds significantly more product than a standard fine-tip serum brush, delivering more serum to the lash and brow line with every application. The result is better coverage, more consistent results, and less product waste.
Yes — our sensitive formula is suitable for all skin types including dry, oily, combination, and reactive skin. It is free from prostaglandin analogues and formulated to minimise irritation.
