Dr. Anna Guanche shares her five must-have skin care products.

If there’s one group of people we tend to trust the most when it comes to skin care, it’s dermatologists. Not only do they examine and treat skin conditions for a living, they almost always seem to have perfect-looking skin. 

We know dermatologists are skin professionals who have access to way more products than the average human ever will, but still, we can’t help but wonder exactly what they use to help keep their skin clear, smooth and glowing. 

On our quest to finding the best derm-approved products, we spoke to board-certified dermatologist and celebrity beauty expert Dr. Anna Guanche. Based in Calabasas, California ― aka Kardashian land ― she counts celebrities like Olivia Culpo, Brandi Glanville and Rebecca Romijn as clients.

We asked her to share the five skin care products she absolutely can’t live without. Check them out below:  

1. EltaMD Skincare UV Clear Broad-Spectrum SPF 46

We all know how important sunscreen is. Guanche told HuffPost via email she uses this EltaMD sunscreen every day on her face, neck, chest and hands.

“I love the tinted kind because it doesn’t look white on my skin,” she said. “I wear makeup daily and the formula is light and non-greasy, allowing me to layer.”

2. RestorSea Pro Intensive Treatment 10X

“This light formulation is an anti-aging serum that reduces pigmentation and visibly smoothes the skin,” Guanche noted. She said she’s especially fond of the active ingredient, Aquabeautine XL, which is “an exfoliant that brightens the skin without irritation, redness or visible peeling.”

“I apply it twice daily to face, neck, chest and hands,” Guanche added. 

3. Alastin Skincare Restorative Neck Complex

Guanche said Alastin Skincare’s Restorative Neck Complex “is wonderful for the neck and décolletage.”

“I apply it daily,” she added, noting, “It not only improves the appearance of the skin in these areas but it helps to prevent further skin aging. The neck and décolletage need to be cared for along with the face.” 

4. Colorescience Total Eye Restore Regimen

“This product is great for rejuvenating and protecting the skin around the eyes, both upper and lower,” Guanche said, adding that the nighttime eye concentrate in particular features “an amazing roller ball” that makes application easy.

The daytime product, meanwhile, helps protect the skin from the UV rays and “at the same time brightens the area.”

“The technology blends with almost every skin type!” she added. 

5. Retin-A (Or Retinol)

Guanche said that Retin-A (aka tretinoin), a topical retinoid that requires a prescription, “is the most powerful anti-aging ingredient, with known science behind it.”

She’s been using it every night for over 23 years, she said, adding, “You will be hard-pressed to find a single dermatologist who doesn’t use it!!!” 

Of course, not everyone can easily get a prescription. As an alternative, Guanche suggested Alastin Skincare’s Renewal Retinol, which contains retinol, a synthetic derivative of vitamin A that’s milder than Retin-A. It’s worth noting that topical retinoids in general can be quite drying, so just make sure to consult with a doctor before you start using.

The Best Vitamin C Serums, According To Skin Care Experts
For the best of the best: SkinCeuticals C E Ferulic(01 of09)
Open Image Modal
The skincare experts who talked to HuffPost overwhelmingly recommend SkinCeuticals C E Ferulic Vitamin C serum, but it doesn't come cheap. "Be aware that Vitamin C serums are a concentrated ingredient, thereby [are] very potent and active," says esthetician Melissa Lekus of Melissa Lekus Skincare Consulting. "So don’t be surprised when your Vitamin C serum is one of the most expensive products in your arsenal." So, what's the difference between a $10 Vitamin C serum and a $100 Vitamin C serum? It's due in part to its formula. "Vitamin C is an unstable molecule on its own, so it works best when combined with Vitamin E or ferulic acid," says dermatologist Tsippora Shainhouse of Rapaport Dermatology.


SkinCeuticals C E Ferulic is available at Dermstore for $166.

For first timers: The Ordinary Magnesium Ascorbyl Phosphate 10%(02 of09)

Dermatologist Erum Ilyas of Montgomery Dermatology recommends first-time users try The Ordinary's Magnesium Ascorbyl Phosphate 10%. It's a water-soluble derivative of Vitamin C, which is a fancy way of saying it's less potent than other forms of Vitamin C. "If it’s someone with lots of sun damage and looking for something more potent, I recommend the Vitamin C Suspension," she says. "The magnesium ascorbyl phosphate is effective and doesn’t tend to feel uncomfortable when used. I’m a fan of The Ordinary — I think of their products as a spice rack. It’s easier to modify routines day to day or week to week (or season to season) because their products have great ingredients. And, you can't argue with their price point."


The Ordinary Magnesium Ascorbyl Phosphate 10% is available at Beauty Expert for $10.50, or SkinStore for $9.60.

For a stable formula: Peter Thomas Roth Potent-C Power Serum(03 of09)

Dermatologist Erum Ilyas of Montgomery Dermatology says that the key to buying a good Vitamin C formula is to educate yourself on its ingredients. "If you are going to look for a Vitamin C-containing product, make sure the concentration and type of Vitamin C is listed. L-ascorbic acid or tetrahexyldecyl (THD) ascorbate are the most active types." She also recommends searching for serums with between 10- to 20-percent concentration, like Peter Thomas Roth Potent-C Power Serum. "If [that's] not the case, Vitamin C can be very unstable on exposure to light, and essentially be useless. That’s money wasted.”

For daily use: Mad Hippie Vitamin C Serum(04 of09)

Though Vitamin C serums are touted as a remedy for sun spots, aging skin and a dull complexion, green beauty expert Annie Tevelin notes that healthy skin starts from the inside out. "Healthy skin really starts within, so eating your daily suggested amount of Vitamin C is great for your overall immunity, so grab fresh foods like kiwi, broccoli, strawberries, grapefruit," says Tevelin, who's also the founder of SkinOwl. "Applying a Vitamin C Serum topically is excellent for transforming dull, lackluster skin, especially post-summer months." She recommends Mad Hippie Vitamin C Serum daily in the mornings, before gradually using it twice daily.

For all-natural ingredients: 100% PURE Vitamin C Serum(05 of09)

Susie Wang, chemist and founder of 100% PURE, recommends prepping the skin at night using a lemon water rinse before applying your serum. "Topical Vitamin C works much faster and directly targets the skin to improve it, whereas ingesting Vitamin C boosts the immune system. Although this helps bolster collagen and elastin production, it's not targeted and works a lot slower since our body only accepts a certain amount of Vitamin C." For ingredient-obsessives, she recommends 100% PURE's Vitamin C Serum to plump skin, improve elasticity and slough off dead skin cells for a brighter, healthier glow.

For dull skin: Dr. Dennis Gross C+ Collagen Brighten & Firm Vitamin C Serum(06 of09)

Vitamin C is a "powerhouse ingredient," says esthetician Melissa Lekus of Melissa Lekus Skincare Consulting. "Vitamin C is the most abundant antioxidant in the body fighting free radicals to slow the aging process." She recommends Dr. Dennis Gross C+ Collagen Brighten & Firm Vitamin C Serum to help with hyperpigmentation, prevent the breakdown of collagen and actually increase collagen production for a smoother, brighter complexion.

For age spots: Citrix Vitamin C Pro-Collagen Brightening Serum(07 of09)

If your main skincare concern is reducing the appearance of age spots and other skin discoloration, dermatologist Melanie Palm recommends Citrix Vitamin C Pro-Collagen Brightening Serum. "Vitamin C is a well-known brightening agent," she says. "It is used topically to fade brown spots without altering normal skin pigmentation.” With any new Vitamin C skincare product, she advises using three to five drops every other morning on the entire face for two weeks before gradually using it every day.


Citrix Vitamin C Pro-Collagen Brightening Serum is available at Dermstore for $114, or Walmart for $77.

For acne scars: Sweet Chef Ginger + Vitamin C Serum Shot(08 of09)

Glow Recipe cofounders Christine Chang and Sarah Lee know a thing or two about glowing skin thanks to their cult-favorite Avocado Melt Sleeping Mask. The duo recently launched an ultra-affordable line called Sweet Chef, that includes a brightening and tone-evening Vitamin C serum. "Vitamin C’s anti-aging, damage-repairing and UV-protecting powers make it a Holy Grail ingredient," Lee says, "but it takes time and consistent application to see the best results." She recommends Sweet Chef Ginger + Vitamin C Serum Shot for hyperpigmentation and acne scars.


Sweet Chef Ginger + Vitamin C Serum Shot is available at Glow Recipe for $20, or Target starting Jan. 27.

For affordability: Oz Naturals Vitamin C Facial Serum(09 of09)

Dermatologist Tsippora Shainhouse of Rapaport Dermatology recommends Oz Naturals Vitamin C Facial Serum for those who want a wallet-friendly serum. "[It's] a much less expensive, vegan-friendly Vitamin C serum with AHA (natural glycolic acid)," she says. "Consumers love the texture and notice brighter skin with reduction in hyperpigmentation over time." She advises wearing it in the morning under sunscreen for protection from free radicals, as well as as nighttime to undo oxidative damage from the day.
