As someone currently in medical school becoming a future dermatologist, i will tell you skincare wont change your skin completely in 1-2 months, it takes time.

Now before i show you everything to avoid, Make sure you check your skincare ingredients before using the product.



____________________________________________

Formaldehyde releases: “Bronopol, DMDM hydantoin, diazolidinyl urea, imidazolidinyl urea, and quaternium-15 are cosmetic preservatives that slowly form formaldehyde


Synthetic fragrances: A heads-up: When an ingredient label simply says “fragrance” or “parfum,” it’s often an umbrella term for hundreds of chemicals that brands aren’t required to disclose.3 (That makes it a heck of a lot harder to discern what may cause a reaction.)


Phthalates: One such sneaky compound hiding under the “fragrance” umbrella? That would be phthalates, which are sometimes used to help perfume stick to skin, as well as eyelash adhesive and nail polish. That’s bad news because phthalates have been shown to be pretty significant endocrine disruptors—in some cases facilitating early puberty in girls and boys, and reduced sperm count in men.4 Oh, and did we mention they’re also harmful to the environment? The EWG reports that some retailers have started to ban phthalate-containing products from their shelves, but we still recommend a healthy dose of skepticism when it comes to added fragrance.


Polyethylene glycol (PEGs): On a similar note: Polyethylene glycol, “propylene glycol (PG) and butylene glycol (BG) could potentially be petroleum derived and irritating to the skin,” says Shrestha. These are chemical thickeners and can sometimes be found in cream-based products.


Siloxanes: Also known as cyclical silicones, these compounds are found in a variety of cosmetic and skincare products—but they’re not great for the environment, and have been linked with endocrine disruption as well.5 (Dimethicone, on the other hand, is considered safer when used sparingly.)


Triclosan: This antimicrobial ingredient (often found in hand sanitizers and antibacterial soap) has been linked to such a significant impact on the thyroid and reproductive hormones that it’s banned in several countries.6 The US has banned it from antiseptic soap, but it might still show up in deodorant, mouthwash, shaving cream, and toothpaste, says the EWG.7


Ethanolamines: While these compounds (which are emulsifiers found in foundation, mascara, and skincare products) are technically classified as safe for cosmetic use by the EWG, they’re also shown to be allergens—something to keep in mind if you have sensitivities to certain ingredients.8 They might be listed as monoethanolamine (MEA), diethanolamine (DEA), or triethanolamine (TEA).


Oxybenzone: A potential endocrine disruptor, oxybenzone can be found in many skincare products that contain sunscreen, "including lotions, lip balms, cleansers, fragrance, and even baby products,” says Shrestha.


Octinoxate: This common sunscreen ingredient was thought originally to be harmful to coral reefs, and although that may have been recently proven false, it's still somewhat irritating to sensitive skin.9


Homosalate: “This is another chemical that’s commonly used in sunscreens as a UV absorber,” says Shrestha. While regulations are starting to wisen up to octinoxate and oxybenzone, homosalate is still pretty commonly used. Read your labels!


Toluene: This chemical (which also goes by the name of Butylated Hydroxytoluene, or BHT), is a big no-no: It’s linked with brain toxicity and can be especially dangerous during pregnancy.10While it’s banned in the EU and Southeast Asia (as well as by a few retailers in the US), you can still find it in nail polish, nail treatments, and hair dye.


Talc: While talcum powder (often used as a smoothing agent in mineral makeup) is generally safe, it also has the potential to be contaminated with asbestos, which is a known carcinogen and instigator of lung disease.11


Per- and poly-fluoroalkyl substances (PFAs) and Perfluorochemicals (PFCs): Remember how we said that the term “fragrance” can potentially be hiding hundreds of chemicals? Well, PFAs are a class of thousands. “They’re fluorinated chemicals that have been found in sunscreens, hair products, and shaving creams,” says Shrestha. “They’re linked to serious health effects, including cancer, thyroid disease, and even reduced effectiveness of vaccines.”


If you commonly use waterproof mascara or eyeliner, take note: PFCs are big culprits here because they’re water repellents.


Teflon: Teflon is one specific PFA worth calling out—it’s the brand name for Polytetrafluoroethylene (PTFE), and is sometimes added to cosmetics to improve the texture. But like other PFAs, it’s linked to hormone disruption and reproductive issues.12


Resorcinol: “This common ingredient in hair color and bleaching products has been linked to skin irritation and immune system dysfunction,” says Shrestha. “In animal studies, resorcinol can disrupt normal thyroid function.”


Carbon black: The EWG has flagged this pigment (which is often found in mascara and eyeliner) because of its possible link to cancer with regard to inhalation (not topical application).13For what it’s worth, the FDA has put some limits on the amounts used—but it’s still widely found in cosmetics at retailers everywhere.


Parabens: “Butyl, propyl, and ethyl parabens have been linked to hormone disruption,” notes Shrestha. These are preservatives that are found in a variety of cosmetics and are probably the most well-known ingredient to avoid due to a 2004 research paper that appeared to find traces of parabens in breast cancer tissue samples.14 According to EU and FDA regulations, parabens in their current form are officially considered safe to use, since cosmetic products only use a very small concentration of these ingredients in their formulas (up to around 0.4 percent, though measurements do differ for each paraben).


It's important to note, however, that parabens may be irritating to some with sensitive skin.



Hydroquinone: This one may surprise you, but the safe use of the hyperpigmentation savior has long been debated, with some countries banning it for its potential carcinogenicity. "Hydroquinone is cytotoxic," explains King. "It kills the cells, thus great for skin brightening, but it has been banned."

you cannot mix retinol with AHAs (Glycolic Acid Toner, Alpha Hydroxy Acid, Lactic Acid, Mandelic Acid Treatment, Apple Cider Vinegar Acid Peel), BHAs (Beta Hydroxy Acid Serum, C-50 Blemish Night Treatment), PHA Toner.
vitamin A supplements.
tetracycline antibiotics.
corticosteroids.
any other acne treatments.
alcohol (or keep it to a minimum)
phenytoin (Dilantin)
strong sunlight and sunbeds.
cosmetic skin procedures, such as waxing or laser treatment.

Mirin for high effort but most people aren't going to read this, much less follow it.

Best to just use 2 or 3 products

Hydroquinone is safe to use in moderation. Those who suffer the side-effects usually don't even cycle it as advised by dermatologists.
However, HQ is safe and effective when used appropriately under medical supervision and within recommended concentrations. Dermatologists often prescribe HQ-based treatments for specific skin conditions and emphasize the importance of correct usage[10]

It isn’t dangerous but look, you must use it proportionally or your skin tone will be un even
 
is tazarotene the best thing to buy
