Facial hyperhidrosis is caused due to overstimulation of eccrine glands. This in most cases doesn't have any specific cause, while it can be hereditary. It can also be caused due to anxiety, substance abuse, menopause, hyperthyroidism or drugs like insulin, pilocarpine etc.”
Sweating produces a naturally antimicrobial peptide called dermcidin, which helps to destroy harmful bacteria on the skin, minimizing the risk for infection, acne breakouts, and flare-ups in chronic skin conditions.
Wash your face immediately after your workout—before you leave the yoga studio, the gym, spin studio, or wherever you break a sweat. It's one a few skin-care rules that you should never break. You don't want a cocktail of dirt, oil, and bodily fluids clinging to your skin, affecting its pH, and clogging your pores.
Primary hyperhidrosis is caused by faulty nerve signals that trigger eccrine sweat glands to become overactive. It usually affects the palms, soles, underarms and sometimes the face. There is no medical cause for this type of hyperhidrosis. It can run in families.
Wear breathable fabrics
The best way to help reduce sweating with your clothing choices is to wear light, breathable fabrics with good ventilation. Lighter colors also help to reflect the sun rather than absorb it, so wearing white can help keep you cool and reduce sweat.
If excessive sweating has no underlying medical cause, it's called primary hyperhidrosis. It happens when excess sweating is not triggered by a rise in temperature or physical activity. Primary hyperhidrosis may be at least partly hereditary.
So, on some level, yes, if someone is out of shape, they are more likely to produce more sweat when they are physically active, but that doesn't necessarily mean their workouts are “better” or “worse.” POP Sugar also says that fit people actually sweat more at the beginning of workouts because their bodies are quicker ...

It's when your sweat has a higher concentration of sodium that you're more likely to see it on your skin (or even your clothing) afterward, she says. This can look like white crystals or a fine white powder on your skin, or even white rings on your clothing, that tend to appear on your chest or back.
Sweat Doesn't Actually Stink (On Its Own)
It's only when sweat gets excreted—and subsequently processed by the bacteria that lives on your scalp, pits and groin—that its distinctive odor rears its ugly head. That is, what you're smelling is actually the digestive byproducts of sweat-sucking microorganisms.
"But make sure you're cleansing your skin immediately afterward," says Jodi Dorf, manager and esthetician at Stars Esthetics Spa in Baltimore. Allowing sweat to dry on the skin can clog pores and cause acne. Dorf explains that sweating is a necessary way for your body to release toxins.
Don't wipe unless you're drenched. Sweat releases heat by evaporative cooling. As each gram of sweat transitions from liquid to gas phase, it absorbs 2,427 joules of energy from the body and dissipates the heat into the environment.
Wiping around the sweat on your face and brows actually rubs any leftover makeup and dirt into your pores. This action will result in clogged pores and acne breakouts post-workout. Instead, try gently dabbing sweat off your face with a cotton towel.
By wiping sweat from your skin, you're likely to sweat even more. That's because sweat is your body's natural air-conditioning system, required to regulate your body temperature. This cooling effect, however, only works when the secreted liquid evaporates on your skin.
