1. Non comodegenic make up. Google. It doesnt clog pores.
2. if you have sensitive skin, do some research, see what triggers it. Chemicals in your makeup that you may be allergic to. So avoid lah.
3. Use reputable brands, e.g Bobbi Brown, Clinique, Sephora, MAC, Estee Lauder etc. Don't skimp and get some unknown weird brand that has god knows what chemicals, and you end up with a HUGE skin problem that'll cost you $$$ to fix.
4. Skin care routine. Start now. Use WATER based moisturisers. Many, many facial aestheticans + aesthetic doctors have said this to me.
5. sunscreen is a MUST. Sunsense is a decent brand, but those with oily skin, check first.
6. Facial wash- use the correct one for your skin type lah.
I can't tell you how many young people do not take care of their skin properly- not removing makeup before sleeping, never wash face properly, no sunscreen.
Then when they're 30 they look 50. Then whine and cry. How lah.
When you are more established & have some money, go see an aesthetic doctor (NOT Dr Ko, the bloodsucker), and get a monthly glycolic peel.
That shit works and isn't crazy expensive.
"Bobbi Brown, Clinique, Sephora, MAC, Estee Lauder" are quite toxic aren't they? Look through their ingredient list again. Usually those popular, mass produced stuffs that are available in most malls or pharmacies, aren't really safe. Good stuffs can't be mass produced.
is there anything to prevent sagging skin
Kigelia africana. It's been used for hundreds or maybe thousands of years to firm or lift sagging skin. But it's hard to find though
