Kiehl's CollaShot Plump Serum - 30ml

For best results, use the serum twice daily, in both the morning and evening, on clean skin.

Yes, this serum is designed to be compatible with most other Kiehl's skincare lines, including the Power Plump series.

While formulated for adult skin, those with highly sensitive skin should patch test the product first as it contains potent active ingredients.

The lightweight, rapid-absorbing gel-to-serum formula is designed to be non-comedogenic for most skin types.

The natural pink hue is a direct result of the vitamin B12 infusion within the formula.

With standard twice-daily usage, a 30ml bottle typically lasts between 4 to 6 weeks.

You may be using too much product. Try using only one to two pumps and massage it fully into the skin until it breaks from its gel phase.

The B12 color should dissipate as the serum absorbs. If it remains, ensure you are allowing enough time for full absorption before applying subsequent layers.

Discontinue use immediately and consult a dermatologist. Patch test on the inner forearm for 24 hours if you suspect sensitivity to specific collagen-boosting ingredients.
