DERMATOLOGIST REVIEW

What Dr. Baumann Says

This is my top choice for patients with dry skin, dark spots, fine lines, and wrinkles who dislike the stinging often caused by other vitamin C serums. I recommend using it in the morning before applying moisturizer and sunscreen to help protect the skin from sun exposure, light, and pollution throughout the day.

Frequently Asked Questions

What makes Alastin C-Radical Defense Antioxidant Serum special?

This serum stands out with its 15 different antioxidants, which work synergistically to reduce free radical damage by up to 74%. Multiple antioxidants, like vitamin C, Coenzyme Q10, and green tea, provide better protection together, supporting collagen and elastin preservation for firmer, youthful skin. Also, it has a higher pH than many Vitamin C serums, so it does not sting. It is more hydrating than most Vitamin C serums. It is only sold by doctors and is considered one of the best medical grade physician dispensed Vitamin C serums.

Which skin types is Alastin C-Radical Defense Antioxidant Serum good for?

Alastin C-Radical Serum is ideal for dry, sensitive, and normal skin types due to its soothing ingredients like squalane, betaine, and centella asiatica. It may feel too heavy for very oily skin but works well for slightly oily and “combination skin”. Oily skin types can use this without  a moisturizer which solves the problem of it feeling heavy on oily skin.

How does Alastin C-Radical Antioxidant Defense Serum brighten skin and
lighten dark spots?

Sodium ascorbate acts as a tyrosinase inhibitor, reducing melanin production to brighten skin. Carnosine blocks melanin through a different mechanism, and lactoferrin helps reduce hemosiderin, an iron-based pigment. Together, they prevent oxidation of melanin and reduce pigmentation. The soothing effects help prevent post inflammatory hyperpigmentation.

Does Alastin C-Radical Antioxidant Serum exfoliate?

No, this serum is not formulated to exfoliate. Unlike other vitamin C serums with a low pH, Alastin's balanced pH ensures it provides antioxidant benefits without exfoliating the skin. This makes it more gentle to use when beginning a retinoid like retinol or tretinoin.

Is the Alastin Vitamin C Serum noncomedogenic?

While this serum is designed to be gentle, ingredients like cetyl alcohol and cetyl palmitate may clog pores, making it less ideal for acne-prone or oily skin.

Can this serum be used immediately after microneedling?

No, Alastin C-Radical Defense contains oils and phenoxyethanol, which can irritate freshly microneedled skin. It's best to wait until the skin has healed before applying. 

Which form of vitamin C is in Alastin C-Radical Defense Antioxidant Serum?

Alastin uses sodium ascorbate, a more stable and less irritating form of vitamin C. This form works effectively at a neutral pH, minimizing irritation while providing strong antioxidant protection, making it suitable for sensitive skin. 

Is Alastin C-Radical Defense Antioxidant Serum easy to apply?

Yes, customer reviews praise its lightweight, non-tacky texture that absorbs easily without leaving residue, making it a breeze to incorporate into daily routines. Unless you  have dry skin, this can be used alone without a moisturizer under a sunscreen. 

Can this product cause an allergic reaction?

If you're allergic to ragweed or plants in the daisy family, be cautious as this serum contains bisabolol (from chamomile) and green tea extract. It also has ingredients like phenoxyethanol, caprylyl glycol, and sodium benzoate, that are not allergens but which may irritate hypersensitive skin.

Does this product irritate sensitive skin?

Most users with sensitive skin find Alastin C-Radical Defense non-irritating due to its higher pH. However, it does contain some potentially irritating ingredients like phenoxyethanol and caprylyl glycol. Despite this, many users report it as less irritating than other vitamin C serums. 

Will Alastin C-Radical Defense Antioxidant Serum help with fine lines,
wrinkles, and skin texture?

Yes, it contains hydrating humectant ingredients like Tremella Fuciformis (snow mushroom), which acts like hyaluronic acid, attracting moisture to instantly plump fine lines and improve skin texture.

Are there peptides in Alastin C-Radical Defense Antioxidant Serum?

Yes, though TriHex peptides are not included due to interactions with vitamin C, it has 2 peptides; carnosine and lactoferrin in the formula. Carnosine helps prevent glycation and reduce pigmentation while lactoferrin promotes healing, removes hemosiderin pigment, and reduces oxidative damage.

Which antioxidants are in Alastin C-Radical Defense Antioxidant Serum?

Alongside sodium ascorbate, this serum features 14 other antioxidants like Coenzyme Q10, green tea extract, physalis angulata, and pomegranate extract, providing comprehensive protection against free radicals and environmental stress. There are the 15 antioxidants in Alastin C-Radical Antioxidant Serum.

Can I use Alastin C-Radical Defense Antioxidant Serum with retinol?

Yes, but be cautious. If irritation occurs, stop using both products and any exfoliants for a few days. Use a soothing moisturizer or oil like argan oil until redness, peeling and sensitivity subside.Can I combine this with a hyaluronic acid serum?Yes, though it's hydrating on its own, pairing it with a hyaluronic acid serum like Alastin's Immerse Serum can provide additional moisture for dry or dehydrated skin. Also, HA serums help other ingredients absorb better and may boost the potency of this antiaging serum.

How long will a bottle of Alastin C-Radical Defense Antioxidant Serum last?

Using the serum twice daily, one pump for the face and one for the neck, should make a bottle last about a month. If the bottle lasts 3  months- you are not using it often enough. 

How long does this vitamin C serum stay effective after opening?

For best results, use the serum within 3 months of opening. Storing it in the fridge can extend its shelf life. 

Where is the best place to buy Alastin C-Radical Defense Antioxidant Serum
online?

The best place to buy is from Skin Type Solutions (STS), trusted by over 200 doctors to store and mail medical grade skin care products. Products are stored in climate-controlled conditions and have rapid turnover to ensure freshness. As an authorized Alastin retailer, STS offers loyalty points, exclusive discounts, sales, gift cards and promotions as allowed by Alastin Skincare corporate rules.
