💐Forms
There are many types of Vitamin C. Yang paling elok, power and well researched is Ascorbic Acid (L-AA). However, it is also unstable, cepat oxidised (tukar warna jadi kuning) and may cause purging.

Other forms are:
1. Magnesium Ascorbyl Phosphate
2. Ascorbyl Glucoside
3. Ethyl Ascorbic Acid

💐Percentage %
We need to know the percentage of the vitamin C used. Kalau rendah sangat %, it might now work. Kalau % tinggi sangat, it may irritate your skin.

💐For beginners: Lower % is better sebab takut kulit tak biasa and pedih
For brightening or glowing: 5%
For pigmentation / dark spots: 15-20%

💐Bila nak guna Vitamin C serum ni?
1. Cleanser
2. Vitamin C
3. Hydrating toner
4. Moisturizer
5. Sunscreen (kalau siang)

If you wanna use hydrating toner first pun boleh, as a buffer supaya kulit tak pedih sangat bila apply vitamin C. Mana mana yang selesa. Kalau Sis Herlysa suka apply on muka yang bersih supaya dapat optimum benefit. Hehe 🌹🌹🌹
