2. Inhibit melanin production
The organic acid components of roselle (such as citric acid and malic acid) can gently metabolize keratin and accelerate epidermal renewal.At the same time, it can inhibit the activity of tyrosinase (a key enzyme in melanin production), thereby reducing pigmentation.It has a certain improvement effect on acne marks, sunspots or uneven skin tone.
3. Moisturizing and water locking
The mucilage and polysaccharides contained in roselle can form a water-locking film, enhance skin moisture retention, and relieve dryness and flaking.Its extract can also regulate sebum secretion, making it suitable for combination or oily skin and helping to maintain water-oil balance.
4. Soothing repair
The flavonoids in hibiscus have anti-inflammatory properties and can relieve redness and stinging caused by sensitivity, sun exposure or external stimuli.Local wet compresses or the use of masks containing roselle can help repair damaged barriers and enhance skin tolerance.
