Description

As a first-step "booster," this serum combines six potent peptides to address multiple concerns: the appearance of pores, sebum, firmness, fine lines, skin tone, and texture. Its watery consistency preps the skin and enhances the effectiveness of subsequent products.

Directions: Use after cleansing as a toner before ampoule, serum or moisturizer. Dispense a few drops and pat gently over the face. Follow with serum and moisturizer.

Warning: For external use only. Avoid contact with eyes. If irritation occurs, discontinue use and consult a dermatologist. Keep out of reach of children. Store away from direct sunlight.

Features
  • Complex of 6 peptides
  • Visibly improves 6 skin concerns (appearance of pores, oiliness, firmness, look of fine lines, uneven tone, and texture)
  • Acts as a primer for other serums

Rated 3 out of 5 by from Not for everyone but a good brand usually I had a really bad reaction to this product. Normally I scour the ingredients list carefully for signs of hidden corn derivatives but for some reason I missed that this product contain xantham gum and citric acid and from the first use it tingled really strongly on me but I thought it might have some sort of Retinols so I still used it for 4 nights until I completely broke out then I stopped and read the box. Sadly I bought two one for home and one for the cottage so I’m out quite a lot of $.
