Skin Concern: Clogged pores can make your skin tired, dull and prone to blackheads. The fix is a pore-opening and detoxing at-home facial.

Mask Formula: Use an antioxidant-rich mask with ingredients like clay for clarifying and lavender for de-stressing, says Sarah Villafranco, MD, creator of Osmia Organics natural beauty line. To make sure your clay mask isn't too harsh, Dakar says to steer clear of black, grainy masks that crack on the skin. Instead, go for ones that contain gentle exfoliating acids, like lactic and citric acids.

How to Apply: Villafranco recommends a multi-step regimen to really de-gunk skin. "[Before applying your mask,] use a clean, very soft washcloth steeped in warm water to steam the pores open and wipe the face clean. Gentle, repeated, upward strokes over the face and neck will provide a mild exfoliation," she says. Spread the mask over your cheeks and T-zone (the most common trouble spots), or simply spot-treat your most congested areas.

Try: GlamGlow YouthMud TingleExfoliate Treatment, $19, a 10-minute mask that draws out impurities with volcanic pumice rock. It also soothes skin with green tea leaf pieces, taking down redness.

Skin Concern: Mature skin needs moisture to help it retain a plumped appearance, especially around fine lines. The delicate eye area is a special concern, since crow's feet come into play. Other concerns with aging are enlarged pores and redness due to broken capillaries.

Mask Formula: Though you might not consider a mask for your under-eye area, Dakar says a targeted eye mask is a must. The intensive treatment helps soften the appearance of fine lines.

For the face, anti-aging masks are all about antioxidants and toning ingredients. Green tea formulas reduce ruddiness that appears especially on the cheeks as we age. Tea also fights free radicals and other aging, environmental stressors. Astringent ingredients like rosewater will help tighten enlarged pores gently. Make sure your mask also has plenty of natural oils in it like omega-3s to help nourish and plump your skin. Lactic and hyaluronic acid will gently exfoliate (you can skip harsh scrubs, which irritate thinning skin), getting rid of any dull surface flakes.

How to Apply: Apply an eye patch mask and rest with your eyes closed for five minutes. This quick treatment will help deliver moisturizing oils to crepe-y eye skin, giving a firmer, more youthful look. For the rest of your face, slather on a mask rich in acids and oils. Use an eye mask and a face mask in conjunction for a full-face uplift.

Try: Patchology FlashPatch Eye Gels, $50, which contain medical-grade hydrogen ingredients for maximum moisture. Caffeine boosts circulation and fights environmental agers.

Philosophy Miracle Worker Miraculous Anti-Aging Lactic Acid Cleanser & Mask, $35, is packed with lactic acids for hydration and gentle exfoliation, plus doubles as a mild cleanser.

Skin Concern: Sensitive skin is prone to breakouts, rashes and irritation due to a plethora of triggers, from stress and hormones to dirt, pollution, weather and skin-care ingredients. Even a blustery day can cause sensitive skin to flake or get welts. Dakar recommends treating reactive skin with the simplest formulas possible. Less is more for sensitive skin, which can react to avoid highly concentrated ingredients and mineral oils.

Mask Formula: Sensitive skin needs calming and detoxing ingredients to bring it back to its perked-up state. Dakar recommends green tea, which is high in antioxidants and calms redness. Villafranco suggests soothing lavender to refresh stressed skin, as well as avoiding harsh chemicals and alcohol, which could cause irritation.

How to Apply: Spot-treat any redness and congested skin with a soothing mask. Be sure not too leave it on your skin too long, as sensitive skin can be reactive to a mask drying for more than a few minutes.

Try: Erborian Perfect Morning BB Mask, $35, which is packed with Matcha green tea for a soothing, morning-skin refresh.

Skin Concern: Acne-prone skin is sensitive in its own way, because it overreacts to an unbalanced moisture level. To keep sore, reactive skin clear and calm, avoid oil-stripping ingredients as well as pore-clogging balms, says Dakar. Acne-prone skin needs calming ingredients like rose that are effective for all skin types, including mature skin.

Mask Formula: "My favorite type of mask for acne-prone skin is a gentle, clay-based one, because they are wonderful at absorbing excess oil and refining the skin," says Dakar.

How to Apply: Apply mask to the t-zone: forehead, nose and jawline -- or wherever you get breakouts.

Try: Fig + Yarrow Clay Mask in Rose, $18, which gently lifts out impurities from your pores. Rose clay is less harsh than black volcanic clay masks, and offers moisture in addition to suctioning out your clog-prone pores.

Murad Clarifying Mask, $37, helps fight blemishes with sulfur, while zinc oxide and licorice root soothe irritated skin. Use this mask for 10 minutes once a week to tone down your breakouts.

Skin Concern: Combination skin can be challenging because you're facing multiple skin problems at once. Most people with this skin type have an oily T-zone and dry cheeks. The easiest solution is to double-up on your masks.

Mask Formula: If you have combination skin, think of your face-mask regimen in steps and layers, advises Dakar. Combining masks creates a customized, targeted approach to your oily and dry patches respectively. Her recommendation: Use a clay mask and a soft hydrating one.

How to Apply: Apply a thin layer of the hydrating mask all over your face and neck, and then, over it, apply a clay mask to any breakout-prone areas such as the T-zone (or simply spot treat if you only have a couple of pesky breakouts). "Always remember to apply the hydrating one first, because a soft mask will not be able to penetrate through a clay or mud one," explains Dakar.

Try: A combination of moisturizing Sonya Dakar NutraSphere Nano Mask, $85, and refreshing Ren Clarimatte Invisible Pores Detox Mask, $34 will have your skin feeling balanced and fresh.
