Accepted Answer

Reduce puffiness by encouraging lymph fluid movement away from tissues

Answer

Gentle lymphatic drainage techniques use light, directional strokes to facilitate the removal of excess interstitial fluid and metabolic waste through the lymphatic system.

Question 3

Retinoids used in professional skincare are derivatives of which vitamin?

Accepted Answer

Vitamin A

Answer

Retinoids are vitamin A derivatives that accelerate cell turnover, stimulate collagen synthesis, and reduce the appearance of fine lines and hyperpigmentation.

Question 4

A client complains of post-inflammatory hyperpigmentation (PIH) following a recent breakout. Which ingredient is commonly recommended to help brighten this discoloration?

Accepted Answer

Niacinamide

Answer

Niacinamide (vitamin B3) inhibits the transfer of melanosomes to keratinocytes, helping to fade post-inflammatory hyperpigmentation over time.

Question 5

What distinguishes a closed comedone (whitehead) from an open comedone (blackhead)?
