helping to keep it hydrated and plump.



How do antioxidants protect the skin?

Antioxidants neutralize free radicals, which can damage skin cells and accelerate aging, thus

How do estheticians assess skin types?

Estheticians evaluate skin type by examining factors like oiliness, dryness, sensitivity, and

the presence of conditions like acne or rosacea.
