Don't buy cheapo lip balm!
I am not sure what is available in Singapore but the brand you
buy depends on personal comfort.
When you decide to re-purchase a lip balm for yourself, TEST
first using a free tester.
Test for consistency - how thick or thin it feels, whether you
like the feel of anything on your lips, gloss factor, stickiness
factor, smell, taste, presence of nutrients, glitter, colour etc.
You don't like it don't buy it.
When I wear make up I wear colour, if I have a plain face
without make up, I prefer no gloss/balm.
Sunscreen is important, lipgloss isn't as important.
Once I had to take some sh--y antibiotics and that cracked my
lips so I did need to purchase lipgloss then.
I got a pot of natural gloss that feels and smells nice with
sunscreen and I hoped did not contain vaseline/petroleum
products.
Cheapest are lipsmackers, then chapstick is a trustable
brand.
For cosmetic purposes I like Chi Chi, MacGlass - although this
is sticky and overrated. Now I use a cheapo $5 one but its very
good quality and value for money.
I also wear lipstick sometimes.
Body shop is also popular here.
I know asians are hot on grapefruit nutrients these days, yeah
good luck with that.
Happy shopping.
