The Three Elements of Moisturizing
1、 Water supplement: external water supplement: replenish skin water by softening water, toner, essence water, spring water, etc; Internal hydration: replenish moisture in the dermis. Method: Drink eight cups of water daily, approximately 2000ml
2、 Water retention: Actively absorbing moisture from the environment through hygroscopic agents, increasing the moisture content of keratin and replenishing lost moisture. (Note: Hygroscopic agent includes: glycerin, hyaluronic acid, butanediol, sodium lactate, urea, aloe, seaweed, plant essence)
3、 Water locking: A hydrophobic oil film is formed on the surface of the skin through a sealing agent, which locks in skin moisture and reduces water loss. (Note: Sealing agents: vegetable oil (olive oil, camellia oil), animal oil (beeswax, fatty acids), vaseline, paraffin.)
Winter, neutral to dry, and dry skin are suitable for choosing oil-in-water creams with more oil and lipids.
