A 0.5 SERUM
WHITE LABEL | GRAY LABEL
Elevated Vitamin A (retinol) activity for aged,
thinning, and coarse, sun-damaged skin.
Available Sizes
1 oz / 30 ml
Product Information
An elegant, light serum with natural extracts that serve also as the vehicle for the vitamin A (retinol) molecule. Refreshing natural scent.
Spread evenly for an undetectable after feel. Twice per week, evenings, for best outcome (observe and adjust).
Some skin warmth may be noticeable for first few applications.
Key Benefits
Lightly emollient, tack free after feel
Helps restore skin thinned by aging and sun
Smooths, adds resilience and improves turgor
Visible change that does not disappear with time
Targeted Skin Type
Unresponsive, coarse aged skin
Thin, sun-damaged skin
Skincare Concerns
Noticeable lines, uneven texture, reduced resilience. A 0.5 SERUM works best for those who want to address more visible sun damage and aging concerns.
Flaking usually not an issue, especially when used appropriately twice per week.
Formulation
Gel-like serum, fast easy spreading, no residual tack.

Ingredient Call Outs
Free of parabens, formaldehyde, formaldehyde releasing agents, phthalates, mineral oil, retinyl palmitate, oxybenzone, coal tar, hydroquinone, sulfates (SLS & SLES), triclocarban, triclosan. Gluten and cruelty free. Acid free. Glycol free.
ACNE SCARS
Apply A 0.5 SERUM twice (2x) per week, evenings.
After two weeks you may add 302 DROPS or 302 SERUM three times (3x) per week and reduce A 0.5 SERUM to once (1x) per week.
Complete smoothing takes several months but noticeable change occurs within first month.
Minimize use of other leave-on products. Avoid makeup, moisturizers and sunblock.
Whenever 302 DROPS or 302 SERUM are in play, exfoliating can be destabilizing. Use only very mild products and very infrequently exfoliate.
Discontinue entire regime for 7 days every month. Let skin rest, cleanse and leave-on REVIVE only.
TIP: Use REVIVE as a cleanser and a leave-on moisturizer to help keep visible blemishes in check.
VISIBLE AGING
Apply A 0.5 SERUM twice (2x) per week, evenings.
After two weeks you may add C 12.5 DROPS or C 12.5 SERUM once (1x) per week, evenings.
Alternately, you could introduce 302 DROPS or 302 SERUM and apply those three times (3x) per week and reduce A 0.5 SERUM to 1x per week.
If you have three actives in play, limit every active to once (1x) per week application.
CERAMIDE SERUM or PRO HYA + also would be excellent choices to use once or twice per week with A 0.5 SERUM.
NEVER have more than three actives in play during a week. Limit every active to once per week to keep skin fresh and not saturated.
Whenever 302 DROPS or 302 SERUM are in play, exfoliating can be destabilizing. Use only very mild products and very infrequently exfoliate.
Minimize other products, especially makeup and moisturizers, avoid sunblock chemistry. Use REVIVE as cleanser, alternate with other cleanser, like 302 CLEANSER. Use REVIVE as moisturizer, too, especially if skin is unstable.
For your skin if these conditions exist:
Exfoliating acids usage is infrequent during the last 30 days
Benzoyl peroxide free for 30 days
Not inflamed or visibly unstable
Sensitive but not visibly unstable
Light to average makeup usage
Not for your skin if these conditions exist:
Inflamed, unstable skin
Unusual oral medications causing skin instability (i.e. chemo, cortisones, thyroid meds) may cause erratic skin behavior.
Recommended frequency of use:
Twice (2x) per week (observe and adjust)
After one month discontinue current active(s) regimen and allow skin to rest for a 7-10 days before resuming. This will allow skin reactions further out to be fresh and not weakened by over frequent or prolonged application periods.
Cleanse:
Note: two or three cleansers are recommended to be cycled through per week for best skin results.
Any 302 Skincare Cleanser or FACE & BODY BAR
Additional actives while using A 0.5 SERUM:
Do not introduce another active for 2 weeks.
Do not apply a second active more often than 2x per week.
You could have a third active in play.
Three actives per week = apply once per week (maximum).
If you have two or more actives in play AND are exfoliating frequently YOU WILL cause skin instability.
Additional leave-ons acceptable:
CALMING MIST recommended if two or more actives in play.
REVIVE, anytime
REMEDY (small pea sized amount for entire face)
LIGHT MOISTURIZER or BALANCE MOISTURIZER (on Actives free days)
Avoid:
Exfoliation
Scrubs
Heavy makeup
Benzoyl Peroxide
Actives are over frequently applied. The visible result then tails off and becomes disappointing usually within a month for receptor driven actives like Vitamin C (C 12.5 DROPS / C 12.5 SERUM, C 25 DROPS / C 25 SERUM) or Vitamin A (A 0.5 DROPS / A 0.5 SERUM, A 1.0 DROPS / A 1.0 SERUM).
The 302 molecule found in 302 DROPS, 302 DROPS PLUS, 302 SERUM and 302 SERUM PLUS is not as unforgiving as Vitamins C and A and B from over frequent application. But.
It is important to observe and adjust your frequency of application to optimize response. This is very different from what other skincare providers advocate. We developed this approach with our own clinicians during the last two decades. We find the concept works and brings you, the end user, into being your own best coach. Observe and adjust.
Be especially observant for the first few applications of an active. If your skin seems to react in a noticeable way, such as feeling warm, becoming pink (but not inflamed) or just much brighter and more plump then you are going to want to apply that product less frequently. That is counter-intuitive but it will have a better visible outcome for you. Do not be surprised if a 1x per week application of a powerful metabolite works just fine.
The reverse is true. You may find an active does meh, very little, after a few applications. Your skin just does not respond. That active is just not going to work for you.
Note: if that unresponsiveness is true for all actives then it is your skin that needs analysis by a professional. CLICK HERE to find the 302 Skincare professional nearest you.
For an in-depth discussion of this application frequency phenomena visit the REFERENCE TOPICS and read through the REPAIR MODEL and the TRAINING MODEL. This will give you perspective on 302 Skincare’s approach which is to surprise the skin (pleasantly), not saturate it.
Think of your skin as a houseplant, avoid overwatering and overfeeding it for best results.
If you have ever tried a product that worked well for you in the first few weeks and then rapidly went downhill, the answer may be the over frequent application of that metabolite weakened your skin. Observe and adjust.
