These three boosters are especially nourishing for post-summer skin : • RADIANCE BOOSTER – 10% VITAMIN C • EVENNESS BOOSTER – 2% ALPHA-ARBUTIN • SOURCE BOOSTER – 1.5 % HYALURONIC ACID + NMF + ATP Boosters can be applied am and/or pm as needed, mixed in the palm of the hand with the Recovery Serum to maximize results, or directly in your usual cream for a boost. 2-3 drops are enough, more can be used if needed. Happy Sunday! ☀️💛
